Precipitated Silicon Dioxide (Si02) Silica Matting Agent HS Code: 281122 Use For PU Wood Coatings





PU lacquers and PUR lacquers can be used on all surface materials. These are two component systems which require a pre-defined amount of activator to be added. Once mixed, the lacquers have pot-life. The solids content is between 25% to 65%. Polyurethane lacquers initially dry physically by means of solvent flashing off and then chemically from the reaction between the resin and the polyisocyante. The result is a hard, flexible film with excellent resistance to chemical and mechanical stress. Polyurethane lacquers are completely non-yellowing. Suitable for demanding areas such as kitchens, bathrooms, office furniture, restaurant furniture and table tops.


Paint Silica matting agent generally used for PU wood coating. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.




Highest matting efficiency

Surface smoothness and improvement in scratch resistance

Excellent transparency

Good Anti-sentiment.
