Technical FAQ

How to prevent blueish haze on dark wood furniture?
To ensure a no blueish silica matting agent for dark wood finish, use GMATT 240. Its precision particle size distribution eliminates the common blue or white haze, ensuring a deep, crystal-clear appearance.
What is the best matting agent for 100% UV coatings?
GMATT U800 is specifically engineered for UV systems. It adapts to significant film shrinkage during the curing process, ensuring a consistent, soft natural matte effect for UV topcoats with unmatched surface integrity.
How to improve scratch resistance in architectural metal coil coatings?
Utilize GMATT 260. Its specialized gel structure acts as a high scratch resistance silica for rolled aluminum, hardening the paint film and preventing mechanical damage during processing.
Do these matting agents affect coating transparency?
No. All GMATT series grades utilize specialized surface treatments designed to match the refractive index of target resins, providing high transparency without masking the substrate.
Are these products suitable for eco-friendly and low-VOC systems?
Yes. The GMATT series is non-toxic and acts as an eco-friendly matting agent for green wood and architectural coatings, fully supporting low-VOC and solvent-free formulations.
