Advantage
XJY-707 is soluble in various organic solvents such as aromatic hydrocarbons/petroleum hydrocarbons. It is insoluble in water and is a widely used silicone intermediate. It is usually used as a silicone end-capping agent. Due to containing reactive Si-H groups in the molecular structure, XJY-707 can be used in the synthesis of copolymer macromolecule by hydrosilylation. The synthesis of copolymer macromolecule can be made into a series of reactive silicone oil. Usually used to produce textile softener, block silicone oil, surface active Agent.
Industrial Utilization
1. As a chain extender for adding liquid silicone rubber, adding a crosslinking agent for forming a hot vulcanized silicone rubber;
2.Used as a waterproofing agent and softener for natural and synthetic fabrics;
3.Special silicone surfactant;
4.Used in the manufacture of a variety of end group reactive linear modified silicone oil.
5.The key intermediates of block copolymerization reaction.
6.Used for modification of the reaction, such as plastic resin.
Packaging
XJY-707 is available in 20kg pails and 190kg plastic drums. Packaging options are available upon request.
