Matting furniture paint, paint, leather, leather, plastics and other special matting surface. Well its hardness, so the film has excellent abrasion resistance and scratch resistance; dispersion and strong, and have a good suspension; placement process does not produce hardprecipitation, there is a good index of refraction. Mesh matting 3000, after the film surface is smooth and delicate, suitable for use in high-end market.
1, color white, light as fluff, was fluffy.
2, chemical stability, non-toxic, odorless, non-flammable, safe to use.
3, good dispersion, ordinary disk disperser 15 m / s can be well dispersed. Good dispersion, added to adjust the gloss after more conducive.
4, when used in coatings, excellent transparency, excellent adhesion after spraying or brushing, smooth coating after drying flat matting effect of excellence, feel extremely smooth, there are certain characteristics in a solvent swelling, anti-settling good. Do not absorb ultraviolet rays,UV curing the coating does not affect the speed.
5, the performance of low oil surplus in aqueous systems. Because it has the same refractive index and polyurethane coatings, so excellent transparency, recoat 10 times not white, the film does not cause yellowing and hair spray.
6, containing a reactive hydroxyl groups can be involved in the crosslinking of the coating film-forming resin, the paint film shrinkageaggregation promoting surface to a uniform unevenness is generated matting, but also to strengthen the film hardness and attrition resistance.
7, because of its prominent acid and alkali resistance, suitable for outdoor wood coatings and corrosion of extinction.
Uses: Suitable for solvent-based and water-based paints, air-drying or drying type paint; leather coatings; paint system; transparent varnish;adhesive type, ink, plastics, pharmaceuticals, paper and other industries.
