LR-610 Spherical Silicone Resin; Polymethylsilsesquioxane

Name: LR-610 Spherical Silicone Resin; Polymethylsilsesquioxane
Brand: Nanjing Silfluo New Material Co., Ltd.

LR-610 is Polymethylsilsesquioxane (spherical silicone resin) micropowder, also known as silicone resin microsphere, which is produced by hydrolysis and polymerization with organosiloxane as raw material. It has the unique properties of silicone materials such as excellent lubricity, light diffusion, hydrophobicity, heat and cold resistance. Compared with other organic polymer microspheres, it has superior heat resistance, does not undergo thermal melting below 400°C, and can maintain a perfect spherical shape. Spherical silicone resin powder is insoluble in organic solvents such as alcohols, esters, ketones, and petroleum fractions, and will not swell in the above solvents.

Siloxane chain link (RSiO3/2)n, this product is a silicone resin powder with three-dimensional network structure, excellent dispersion and heat resistance. There are types of surface hydrophobic treatment.

CAS NO: 68554-70-1

Applications:

1. LED lampshade industry: As a light diffusing agent for LED light diffusing plastics, it has heat resistance, high haze and high light transmittance;

2. Cosmetics industry: smooth feel agent, filler;

3. Synthetic resin and rubber system: Added to epoxy resin, acrylic resin, polyester resin, ABS synthetic resin, rubber and other systems to give the surface of plastic products with wear resistance, scratch resistance and a smooth feel;

4. Coatings and paints: imparting dispersibility to coatings, inks, varnishes, etc., imparting a smooth feel and matting to the coating film;

5. Other applications: improving the dispersion, fluidity, anti-agglomeration and caking of pigments and ceramic powders.
