Does FG-ZM01 leave residue or affect fired body properties?

FG-ZM01 burns out cleanly during firing and has no negative effect on fired body properties. The L.O.I. (loss on ignition) contribution from the binder is accommodated by the product's chemical composition design (see spec table). No sandwich, black-core, or color deviation has been reported in validated production applications.

Ceramic Body Binder FG-ZM01: 30–70% Green Strength Enhancer for Ceramic Bodies

PRODUCT DETAILS

Goway Ceramic Body Binder (FG-ZM01) is an organic polymer co-polymer additive engineered to increase green (unfired) ceramic body strength while simultaneously improving slurry flow and spray-drying granule quality. Unlike lignin- or cellulose-based binders, FG-ZM01 remains stable long-term in slurry, does not produce sandwich or black-core defects in the fired body, and can reduce deflocculant usage — contributing to measurable energy savings in spray-drying operations.

Performance Characteristics

The following performance attributes are documented from Goway in-house testing and field validation. All strength and flow data are indicative; actual results vary with body formula, clay quality, and process conditions.

Quick Selection — FG-ZM01 vs Lignin / Cellulose-Based Ceramic Binders
Decision Factor	FG-ZM01 Ceramic Body Binder	Lignin / Cellulose-Based Binder
Green Strength	30–50% increase at 0.15–0.3% dosage	Variable; often requires higher dosage or formula adjustment
Slurry Flow	Maintains or improves flow; Ford Cup flow time improves by 5–10 s in validated applications	May increase viscosity or require extra deflocculant correction
Slurry Storage Stability	Long-term stable in slurry, suitable for continuous mill operation	May degrade within 24 hours depending on slurry chemistry
Black-Core / Sandwich Risk	No sandwich or black-core defects reported in validated production applications	Higher risk because organic residue may affect burnout behavior
Best Fit	Tiles, porcelain, sanitaryware and ceramic bodies with unstable clay quality	Basic body strengthening where firing defects and slurry aging are less critical

Green Strength Increase: 30–70%

At 0.15–0.3% addition, FG-ZM01 increases ceramic green (unfired) body strength by 30–50%, reducing breakage during pressing, transfer, and early drying stages. _(Goway in-house testing, 2025.)_

No Viscosity Penalty — Flow Improvement

Unlike traditional binders, FG-ZM01 does not increase slurry viscosity. In validated production applications, Ford Cup flow time improved by 5–10 seconds after addition. _(Goway in-house testing, 2025.)_

Spray-Drying Granule Optimization

The 40–80 mesh fraction of spray-dried powder increases significantly while over-fine (<40 mesh) and over-coarse (>80 mesh) fractions decrease. More uniform granule size distribution reduces pressing defects and improves green density. _(Goway in-house testing, 2025.)_

Lower Hollow Granule Rate

Powder bulk density after spray-drying increases measurably, reflecting a lower hollow granule rate. This contributes to more consistent pressing behavior and reduced pin-hole risk in fired bodies.

No Sandwich / Black-Core Defects

FG-ZM01 burns out cleanly at 300°C and does not contribute carbon contamination to the fired body. No sandwich or black-core phenomena have been reported in validated production applications. Contrast with lignin-based binders, which commonly cause this defect.

Reduces Deflocculant Demand

Because FG-ZM01 improves slurry flow independently, the deflocculant (e.g., STPP) dosage can often be reduced. This can lower slurry water content and reduce spray-drying tower energy consumption. Cost Option

Long-Term Slurry Stability

FG-ZM01 remains effective over extended slurry storage periods. Unlike lignin or cellulose binders, which degrade within 24 hours, FG-ZM01 does not decompose in slurry — eliminating time-sensitive addition constraints in continuous mill operations.

Reduces Dependence on Clay Quality

For bodies that use lower-plasticity clays or high barren material ratios, FG-ZM01 compensates for reduced natural binding capacity, broadening the range of acceptable raw material inputs. APPLICATION

Condition	Ford Cup Flow Time (s)	Green Body Strength (MOR, MPa)
With Goway FG-ZM01 (0.4%)	33	1.53
With competitor binder (0.4%)	36	1.23
Lower Ford Cup time = better flow. Higher MOR = stronger green body. Test conducted on identical floor tile body formula. Results are indicative; vary with specific formula. Request Goway TDS for detailed test protocol.

Application Scenarios

FG-ZM01 is suitable for a broad range of ceramic body types. The two primary scenarios below represent the highest-value use cases based on field evaluation. Contact Goway for application testing support tailored to your specific body formula.

Scenario A — High Green Strength Demand APPLICATION

Applicable when the production line experiences recurring body breakage during pressing, demolding, transfer conveyor, or early drying — typically linked to insufficient green body strength.

Body breakage rate >2% at pressing or demolding stage
Green body MOR below target (e.g., <1.0 MPa for large-format tiles)
Low-plasticity clay supply, variable raw material sources, or high barren material content (>40%)
Bodies prone to cracking during drying, especially with fast-drying kiln schedules
Large-format tiles (≥600×600 mm) or thin-body formulations where mechanical handling stress is amplified

Selection Note: In this scenario, FG-ZM01 at 0.15–0.3% typically delivers 30–50% green strength improvement. Start with 0.15% and increase in 0.05% increments while monitoring MOR and flow time.

Scenario B — Spray-Drying Process Optimization APPLICATION

Applicable when spray-drying powder shows excessive fines or coarse fractions, high hollow granule rate, or when pressing defects are traced to non-uniform granule size distribution.

Spray-dried powder over-fine fraction (<40 mesh) >20% by weight
Powder bulk density below target, indicating high hollow granule proportion
Pin-hole or lamination defects in pressed tiles traced to granule quality
Desire to reduce deflocculant (STPP) dosage and lower slurry water content
Spray-drying tower energy cost identified as a priority reduction target

Selection Note: FG-ZM01 improves granule size distribution and reduces hollow granule rate by modifying polymer chain interactions during atomization. Reduction in STPP dosage is a secondary benefit; monitor flow time closely when adjusting both variables simultaneously.

Scenario C — Replacing Lignin or Cellulose Binders NEW

Applicable when current binder (lignin sulfonate, CMC, or similar) causes sandwich/black-core defects, degrades rapidly in stored slurry, or creates odor and dust issues in the production environment.

Black-core or sandwich defects in fired body attributed to binder carbon residue
Binder effectiveness declines after >24 hours in slurry storage
Slurry viscosity too high with current binder, forcing reduced dosage and insufficient green strength
Worker health or environmental compliance concerns from binder odor or dust

Industry Insights & Common Considerations

Practical observations from ceramic body binder application across floor tile, sanitaryware, and large-format tile production environments.

INSIGHT #1 — Green Strength vs. Slurry Flow: Not a Trade-Off with Polymer Binders

A common assumption in ceramic body formulation is that increasing binder content to raise green strength necessarily degrades slurry flow. With traditional organic binders (lignin, CMC), this trade-off is real: viscosity rises with dosage. Organic polymer binders like FG-ZM01 operate through a different mechanism — polymer chain entanglement under drying rather than viscosity-driven adhesion in the wet state — which allows green strength to increase without a flow penalty. _(Goway in-house testing, 2025.)_

INSIGHT #2 — LOI Budget: Account for Binder Contribution

FG-G301 and FG-G303 have L.O.I. values in the 6–7% range. When dosing at 0.2% by body weight, the binder's own L.O.I. contributes approximately 0.012–0.014% to the total body L.O.I. — a negligible amount for most tile formulations. For technical ceramics or sanitaryware with tight L.O.I. budgets, FG-G301 (L.O.I. 5–6%) provides a lower-LOI option.

INSIGHT #3 — Moisture Sensitivity: Storage Is Critical

FG-ZM01 grades are hygroscopic. Opened bags must be resealed and stored in a dry environment. Product exposed to significant moisture absorption may cake but retains effectiveness after re-dispersion in water. Do not store near heat sources (ignition risk at elevated temperatures). Follow local flammable materials storage guidelines.

Frequently Asked Questions

What is a ceramic body binder and why is it used?

A ceramic body binder is an additive that increases green (unfired) body strength so tiles and ceramics can withstand handling, pressing, and drying without cracking. FG-ZM01 from Goway is an organic polymer binder that achieves a 30–50% green strength increase at 0.15–0.3% dosage, without raising slurry viscosity.

How does FG-ZM01 compare with lignin-based or cellulose-based (CMC) binders?

Unlike lignin or cellulose binders that can cause sandwich/black-core defects in the fired body and degrade within 24 hours in slurry, FG-ZM01 remains stable long-term in slurry, produces no dark core, and has no odor or dust concerns. It also improves slurry flow rather than increasing viscosity, allowing for higher effective dosage without flow penalties.

What is the recommended dosage of FG-ZM01?

The recommended dosage for FG-ZM01 is 0.15–0.3% by dry body weight. For FG-G301 and FG-G303, the typical range is 0.1–0.2%. Exact dosage depends on body formula, clay quality, and target green strength. Goway provides application testing support and can recommend a starting point based on your formula.

Does FG-ZM01 affect slurry flow or spray-drying performance?

FG-ZM01 does not increase slurry viscosity. In validated production applications, Ford Cup flow time improves by 5–10 seconds after addition. Spray-drying performance also improves: the 40–80 mesh fraction of powder granules increases significantly while over-fine and over-coarse fractions decrease, giving more uniform granule size distribution and a lower hollow granule rate. _(Goway in-house testing, 2025.)_

Can FG-ZM01 reduce deflocculant (STPP) usage?

Yes. Because FG-ZM01 improves slurry flow independently, the amount of ceramic deflocculant (such as STPP) required can often be reduced. This can lower overall slurry water content and reduce spray-drying tower energy consumption. Adjust deflocculant dosage gradually while monitoring flow time to avoid over-adjustment.

What ceramic body types is FG-ZM01 suitable for?

FG-ZM01 is suitable for floor tiles (including large-format polished tiles, quartz tiles), wall tiles, sanitaryware, daily-use ceramics, and ceramic bodies with high barren material content. It is especially beneficial in bodies where clay quality is variable or where green strength is a persistent production challenge.

Does FG-ZM01 leave residue or affect fired body color?

FG-ZM01 burns out cleanly during firing with no negative effect on fired body color or mechanical properties. No sandwich, black-core, or color deviation has been reported in validated production applications. The binder's L.O.I. contribution at typical dosage (0.2%) is approximately 0.012–0.014% of total body L.O.I. — negligible for standard tile formulations.

How should FG-ZM01 be added to the slurry?

FG-ZM01 can be directly added to the ball mill along with the formulation raw materials. In most applications, it is recommended to add it together with the formulation materials during the ball milling process to ensure complete dispersion. Store the opened bags under sealed and dry conditions; FG-ZM01 is hygroscopic.
