Technical FAQ
Expert solutions for wood coating formulation challenges.
+How to achieve zero haze on dark walnut finishes?
To eliminate blueish haze on dark substrates, the GMATT 200 Series features an optimized refractive index. This high transparency silica matting agent ensures a zero haze wood finish, preserving the natural depth and clarity of dark walnut or mahogany grains.
+Which silica provides the best soft-touch feel?
The GMATT 200 Series is a premium wax treated silica matting agent. Its specialized surface treatment delivers a soft-touch furniture finish, elevating tactile perception while enhancing the scratch resistance of luxury wood topcoats.
+How to prevent hard caking in low-VOC wood paint?
The GMATT 200 Series ensures long-term storage stability in wood paint. Its organic modification prevents hard caking in low-VOC and waterborne systems, allowing for easy redispersion even after prolonged shelf storage.
+Is GMATT 200 Series compliant with ASTM D523?
Yes. Our silica provides precise gloss control compliant with ASTM D523. It ensures consistent specular gloss measurements at 20°, 60°, and 85° for everything from dead-matte to high-end satin wood finishes.
+Is it suitable for waterborne PUD systems?
The GMATT 200 Series is the ideal paint gloss reduction agent for waterborne polyurethane (PUD). It achieves high environmental compliance without compromising the film’s clarity or smooth-touch characteristics.
Recommended Solution
To achieve a crystal-clear matte finish in high-end wood formulations, we highly recommend GMATT 240 for its superior clarity and efficiency.
