Eliminating "plastic glare" with eco-friendly precision. Our synthetic amorphous silica is engineered to meet global ZDHC and OEKO-TEX standards for luxury PU and PVC leather finishes.

Enhance perceived value. Our highly porous PU leather matting powder scatters light at the micro-level, delivering a deep dull finish silica for synthetic leather without masking the base color.
Superior "Hand-feel". Beyond aesthetics, our silica imparts a smooth, warm "soft-touch" feel to the surface, closely mimicking the tactile experience of genuine animal leather.
Low-VOC compatibility. As a premier eco-friendly silica matting agent for leather finish, it disperses rapidly in waterborne polyurethane (WPU) systems, meeting the strictest VOC limits.
Endure constant flexing. Our nano-engineered particles integrate into the polymer matrix without causing micro-cracking, preserving the flexibility and stretch of synthetic fabrics.
Sustainable finishing and tactile optimization solutions.
The "plastic glare" is caused by specular reflection from smooth resin surfaces. Incorporating our dull finish silica creates micro-roughness that diffuses light, resulting in the sophisticated matte appearance required for automotive and upholstery leather.
Yes. SEMITECH synthetic amorphous silica is high-purity and free from restricted hazardous substances. It is fully compliant with ZDHC and OEKO-TEX guidelines, ensuring safety for human contact and environmental protection.
No. Unlike coarse mineral fillers, our nano-engineered PU leather matting powder has an optimized particle size and pore volume. It maintains coating flexibility, allowing the synthetic leather to undergo thousands of flex cycles without cracking or stiffening.
Absolutely. Our eco-friendly silica matting agent is surface-treated to interact perfectly with water-based resins, providing a dry, warm, and luxurious tactile experience that mimics genuine animal leather in sustainable WPU systems.
Our silica is designed for rapid dispersion. In most leather coating formulations, it can be fully incorporated using standard high-speed dissolvers within 15-20 minutes, ensuring a smooth, grit-free finish on the final leather surface.
For high-end eco-leather and textile finishes, we recommend our GMATT WB Series for its exceptional clarity and sustainable profile.
