Aerogel silica

Product Description:

Gaia-AGS 300 is a silica manufactured by the aerogel process, containing almost pure silica.  It is a white fine powder and can be used as high efficient matting agent in clear and pigmented water based coatings to provide excellent performance:  excellent matting efficiency, dispersibility, and transparency.  It is suitable for clear and pigmented coatings, particularly for clear coatings hard to matte; and for waterborne finish coat (skin coat) on leathers and artificial leathers.    

Uses:  suitable for use as matting agent in clear and pigmented coatings, particularly for clear coatings hard to matte, and for waterborne finish coat on leathers and artificial leathers.
