Aerogel Micronized Silica Powder , 1.8 - 2.0ml/G Porosity Aerosil Fumed Silica

Excellent Transparency Aerogel Silica Matting Agent CAS No.: 7631-86-9 Used For PU Wood Coatings

Description

Silica Matting Agent Generally Used For PU Wood Coatings. Polyurethane wood coatings have excellent versatility and exceptional chemical and physical resistance. Polyurethane coatings for wood applications are available for one-component (1K) or two-component (2K) solventborne or waterborne systems. Polyurethane wood coatings provide a flexible, functional and aesthetic solution to preserve and protect wood’s natural beauty. Silica Matting Agent can make the matt and semi-matt PU wood coatings.

Characters

1, Outstanding matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.

2, Better transparency: High purity of silica product ensures that refractive index can inosculate with resin index.

3, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.

Applications

1, Furniture Wood Coating, Melamine wood coatings, PU wood coatings, NC Wood Coatings, UV Wood Coatings.

2, Automotive Coating, Car Coating, Motorcycle Coating, Truck Coating, Bicycle Coating.

3, Industrial Coating, Metal baking Coating, Decorative Coating.
