Modern consumers demand synthetic leather that looks, feels, and performs like the real thing, without the harmful environmental footprint. To eliminate the cheap “plastic glare” of raw polyurethane resins, formulators require an exceptional dull finish silica for synthetic leather.
SEMITECH’s engineered particles are classified as high-purity synthetic amorphous silica. They are strictly designed to comply with global eco-textile standards, such as OEKO-TEX and the ZDHC (Zero Discharge of Hazardous Chemicals) guidelines, ensuring your coatings are safe for both the environment and human contact.

High gloss on PVC and PU synthetic leather instantly reduces perceived value. Our highly porous PU leather matting powder scatters light perfectly at the micro-level, delivering a deep, sophisticated dull finish without compromising the underlying color.
Beyond visual aesthetics, the tactile experience is crucial. By utilizing specialized surface treatments, our silica imparts a smooth, dry, and warm “soft-touch” feel to the textile surface, closely mimicking genuine animal leather.
As the industry moves away from solvents, our product shines as an eco-friendly silica matting agent for leather finish. It disperses rapidly in waterborne polyurethane (WPU) systems, enabling formulators to achieve extremely low VOC limits.
Textile and leather coatings must endure constant flexing. Unlike coarse fillers that cause micro-cracking and stiffen the fabric, our nano-engineered silica integrates flawlessly into the polymer matrix, preserving the original flexibility and stretch of the leather.

To remove the unnatural plastic shine, you must incorporate a highly efficient dull finish silica for synthetic leather into the topcoat. The silica particles create microscopic surface roughness, which scatters incident light in all directions, creating a smooth, non-reflective appearance.
Yes, absolutely. Synthetic amorphous silica is inherently non-toxic, chemically inert, and contains no crystalline silica. It is widely approved for use in eco-friendly textiles and complies with strict global regulations regarding skin contact and environmental safety.
The best PU leather matting powder is one that provides high matting efficiency at low dosages to preserve the flexibility of the polyurethane resin. SEMITECH’s engineered silica is specifically designed to wet-out quickly in PU systems, providing a premium dull finish without stiffening the material.
An effective eco-friendly silica matting agent for leather finish features a tailored surface polarity. This allows the silica powder to be easily dispersed into waterborne polyurethane (WPU) without requiring high-shear milling, preventing foam generation and maintaining low VOC levels.
No, provided you use the correct grade. Poor-quality or oversized fillers can disrupt the polymer film, leading to cracking during flexing. Our precision-milled synthetic amorphous silica maintains the integrity and elasticity of the coating matrix, ensuring long-lasting durability.
