Ⅰ. Product Features
- Targeted Performance: This Solid Silicone Resin for Polysiloxane Coatings is a specialized organosilicon polymer that is solid at room temperature and possesses excellent color and light keeping performance along with high reactivity.
- Superior Hardness & Compatibility: It features high hardness and good compatibility, allowing it to be used with acrylic, polyester, and epoxy resins to enhance heat and weather resistance.
- Chalking & Cracking Resistance: It is specifically designed to improve film durability, particularly in resisting chalking and cracking under harsh conditions.
Enhanced Recoatability: Compared to other solid silicone resins, BX-ESR-408 has a significantly lower impact on recoating properties, ensuring better interlayer adhesion.
Standards Compliance: It provides coatings with exceptional weatherability and salt spray resistance, meeting the HG/T 4755-2014 industrial standards for polysiloxane coatings.
