GMATT U800 provides exceptional transparency and scratch resistance across multiple advanced industrial sectors.
Ideal for 100% UV-curable wood lacquers and premium furniture topcoats, allowing natural wood grains to remain visibly clear.
Highly recommended for 100% UV-curable PVC flooring and industrial sheet coatings, dramatically enhancing abrasion endurance.
Perfect for demanding plastic substrates, including 3C electronic casings and automotive interior plastic parts.
GMATT U800 must be stored in tightly closed containers under dry conditions, protected from volatile substances and humidity.
Shelf Life: Must be used within 2 years after manufacturing to ensure optimal matting performance and dispersion.
Direct answers for formulators and procurement engineers regarding GMATT U800 performance.
A: By utilizing an optimized particle refractive index. Engineered using a high-purity gel process, it delivers ultra-transparent films even at high loading levels, allowing natural wood or PVC textures to remain highly visible.
A: It prevents viscosity spikes and maintains rheological flow. GMATT U800 features a controlled oil absorption of 130 - 180 g/100g, allowing formulators to achieve high matting efficiency in solvent-free systems without compromising leveling.
A: Yes. It requires only standard high-speed stirring. It integrates seamlessly using a dissolver, eliminating the need for intensive bead milling and significantly reducing processing time and energy consumption.
A: It acts as a structural reinforcing filler. By strengthening the polymer matrix, it provides exceptional scratch resistance and abrasion endurance, which is crucial for high-traffic surfaces like PVC flooring.
A: No. It is chemically inert and maintains shelf stability. With a stable pH (6.0 - 8.0) and specialized surface treatment, it ensures minimal impact on photoinitiator activity and the chemical curing process.
