Introduction: 

Scattering powder product features

1. Excellent heat resistance, far beyond the traditional organic polymer. Even under the condition of 400 ℃, it does not melt and has little weight loss; under the condition of high temperature melting processing of engineering plastics such as PC, the color is stable and does not turn yellow.
2. Good solvent resistance, insoluble and non swelling in common organic solvents.
3. It has good dispersion in synthetic resin and rubber system, and can improve lubricity and antiwear.
4. The loss of impact resistance and processability caused by the addition of ordinary flame retardant can be restored.
Improve the high temperature forming, heat resistance and extrudability of engineering plastics and modified engineering plastics.
5. It can significantly improve the enhanced light diffusion performance, reduce light loss, and maintain a good balance between light transmission and uniformity.

Main Application: 

1. Coating ink: suitable for coatings and ink additives with high heat resistance and solvent resistance.
2. High transparent matting powder: after the spherical powder of silicone light diffusing agent is added to the coating, it can form small bumps on the surface of the coating film. Because the tiny unevenness scatters light, it can play a good extinction effect.
3. Scratch resistant agent: the cross-linked product has good toughness and scratch resistance. It can make scratch resistant paint for high-quality wood paint
4. Hand feeling improver: the product has a softer texture than inorganic matting agent, which can make the product surface have excellent touch.
Compared with inorganic powder, the proportion of spherical micro powder of silicone light diffusing agent is only 1.20, which is easier to disperse and difficult to precipitate. When combined with the coating, it has excellent adhesion, especially fine hand feeling, and can form a coating with higher quality feeling on the surface.
5. Film anti adhesion (opening agent): it can be used as anti adhesion agent for polyethylene and polypropylene films; The spherical appearance can prevent the film surface from being damaged. Its superior light transmission performance can maintain the transparency of the film and prevent particles from falling off from the film surface. It has excellent temperature resistance, yellowing resistance and high durability.
6. Light scattering agent: in resin processing, silicone light diffusing agent can be used as light scattering agent to obtain translucent sanding effect. Compared with inorganic powder, this product has excellent compatibility with resin and is easier to disperse in resin.
7. Powder surface modification: silicone light diffusing agent has strong triboelectric characteristics. Therefore, after dry mixing, it will quickly disperse on the surface of plastic, organic powder, pigment, ceramic, inorganic powder, metal powder and other particles, and uniformly adhere to the orderly mixing on the surface of powder particles. Due to the formation of this orderly mixing, the mixing characteristics, fluidity and formability of the powder are improved, which can be used as additives for toner and carrier, additives for ceramic molding, etc.

Feature: 

1. Compared with inorganic light diffusing agent, it has high diffusion efficiency, good compatibility with matrix resin, good dispersion, small specific gravity, low water absorption, good water repellency, and more balance between light transmittance and uniformity;
2. Compared with the traditional acrylic light diffusing agent, it has high light diffusing efficiency, low addition, excellent heat resistance, high brightness, and can maintain ideal light transmittance;
3. Compared with acrylic light diffusing agent, it has excellent heat resistance and high temperature resistance, and the service life of lamp box lampshade is longer. The light diffusion efficiency is higher and the addition amount is lower. High cost performance.
4. According to different requirements of light diffusion and transmittance balance, different specifications of pure silicone light diffusing agents can be provided;
5. The light diffusion efficiency is high and the addition amount is low, generally about 0.5-0.8%, which can be adjusted according to the thickness, surface microstructure and the combination with other additives.
