Product Description of PMMA Powder:
1. It has excellent oil absorption performance and can better absorb sebum, sweat and other skin secretions;
2. Wide particle size range, ultra-fine powder, particle size coverage from 1 micron to 20 microns, multiple specifications and models;
3. The characteristics of high refractive index make the incident light scattered, dilute the contrast of light and dark on the face, and achieve the concealing effect;
4. The spherical structure endows cosmetics with good slipperiness and excellent silky feel;
5. It has good dispersibility and stability in liquid cosmetics containing organic solvents (ethanol, etc.);
6. The transparent property allows part of the light to pass through, reducing the paleness of the face and achieving a natural makeup effect.
Product application:
The skin feels smooth and has excellent spreadability. PMMA powder is mainly used for paint and ink products, and is widely used in the production of high-end powder, eye shadow, blush, BB cream, sunscreen, shampoo and other cosmetic products.
For coating films: high gloss, gorgeous appearance, excellent weather resistance, stain resistance, chemical resistance, excellent solvent resistance, retort resistance, high hardness, excellent flexibility, adhesion to substrates and Thermal decomposition.
Used in coatings: low VOC, excellent pigment dispersion, quick drying, easy application paintability, low odor, good solubility in weak solvents
Used for ink: PMMA powder is mainly used for mobile phone protection screen and ink application. This product is divided into two types: hardened coating and no hardened coating. It is characterized by excellent light transmittance, no impurities, electrostatic protective film, and surface hardening. After thickening, the hardness can reach 4-6H or more. At present, PMMA materials are especially recommended for hardening treatment.
