1.Building waterproof materials. Mainly used to prepare hydrogen silicone emulsion, which is used as waterproof/antifouling agent for gypsum board, marble and floor tile.
2.Fabric waterproof material. KF-202 and hydroxyl terminated silicone oil are mixed into emulsion, and zinc chloride is added as catalyst to give durable waterproof performance to fabrics and leather
3.Powder material modifier. Powder modification of dry powder fire extinguishing agent to improve the flow performance of dry powder
4.Interface modifier of rubber. Adding an appropriate amount (about 3%) of KF-202 to the silicone compound can improve the processing performance of the compound and prevent the structure.
5.Preparation of crosslinking agent for addition molding silicone rubber. An important component of addition silicone rubber, the addition of silicon hydrogen and silicon vinyl completes the curing process of silicone rubber
6.Basic raw material of modified silicone oil. KF-202 can be used to prepare long-chain alkyl silicone oil (silicone wax), phenylethyl side-chain modified silicone oil, fluoroalkyl side-chain modified silicone oil and other special silicone oil
7.Silicone aerogel. Dissolve KF-202 in methanol, add alkali to catalyze crosslinking, form gel, and freeze dry to obtain high-quality aerogel
8.Silicone rubber foaming agent. In the vulcanization process of silicone rubber, KF-202 can decompose to produce hydrogen under the catalysis of high concentration of platinum, making silicone rubber foam
