Matting furniture paint, paint, leather, leather, plastics and other special matting surfaceWell its hardness, so the film has excellent abrasion resistance and scratch resistanceDispersion and strong, and have a good suspensionPlacement process does not produce hardprecipitationthere is a good index of refraction. Mesh matting 3000after 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-toxicodorlessnon-flammable, safe to use
3, good dispersionordinary disk disperser 15 m / s can be well dispersedGood dispersionadded to adjust the gloss after more conducive
4when used in coatingsexcellent transparencyexcellent adhesion after spraying or brushingsmooth coating after drying flat matting effect of excellence, feel extremely smooth, there are certain characteristics in a solvent swellinganti-settling good. Do not absorb ultraviolet raysUV curing the coating does not affect the speed
5, the performance of low oil surplus in aqueous systemsBecause it has the same refractive index and polyurethane coatings, so excellent transparencyrecoat 10 times not whitethe film does not cause yellowing and hair spray
