1. This product can improve the mechanical and electrical properties of glass fiber reinforced thermosetting resins containing inorganic fillers (such as unsaturated polyester, polyurethane and acrylate) and thermoplastic resins (polyolefin and thermoplastic polyurethane). It can also improve the wear resistance, hardness, strength, heat resistance and water resistance. It has excellent finish and greatly improves the impact resistance (such as application). In FRP composites.
2. In coatings, it has strong support, thixotropy, sedimentation effect on coatings. Surface finish, adhesion and other properties are also very helpful. It can also be used as settling agent to improve the stability of pigments and increase the anti-corrosion effect.
3. In composite liquids (e.g. two-component polyurethane coatings), rheological properties can be effectively controlled.
4. Excellent hydrophobicity and stable thixotropy, anti-sedimentation, anti-flow hanging, thixotropy thickening in coatings and inks.
5. It has good hydrophobicity and rheological control in adhesives and sealants.
6. In the production of silicone rubber, the transparency of vulcanizate is improved, the technological process is shortened effectively, the vulcanization time is reduced, the tensile strength is increased and the elongation at break is improved.
7. In the production of EPDM, NBR and butyl rubber, the reinforcing effect of EPDM is better than that of most similar products on the market because of the original surface modification technology. It can also reduce the curing time and improve the physical properties and phase of rubber.
8.Applied in the field of plastics, the basic crystallinity and friction coefficient can be reduced, and the tensile strength can be greatly improved. Hardness and wear resistance.
