YS-235 (B) is a one-component room temperature curable high-temperature resistant silicone sealant, which reacts with water molecules in the air at room temperature and solidifies into a tough rubber like solid. It has superior high and low-temperature resistance and can be used in high and low-temperature environments of -40 ºC -400 ºC. Bonding and Sealing for ABS, PVC, and other plastics, microcrystalline glass, coated glass, metal, and other products with high-temperature resistance requirements. It can also be extruded under a wide range of climatic conditions, and quickly react with the moisture in the air to solidify into a durable, high-performance, and elastic colloid; High aging resistance, moisture-proof and waterproof performance, fully conforms to the requirements of EU ROHS directive.
