Hydrogen-Terminated Silicone Oil LC-HT3K-20K

Low Cyclic Content Hydrogen Terminated Silicone Oil

D4/D5/D6<0.1%

LC-HT is a series of hydrogen-Terminated Silicone Oil with different molecular weights and viscosities. It’s molecular weights range from 3K-20K. It is a linear polydimethylsiloxane with Si-H active hydrogen groups at both ends of the molecular chain, and is a key crosslinking agent and modification intermediate in addition type silicone systems. It can undergo hydrosilylation reaction with vinyl silicone oil under catalyst, forming a stable cross-linked network, and can also be used for surface modification of organic and inorganic materials. It is a core raw material in the fields of liquid silicone rubber, coatings, waterproofing agents, release agents, etc.

Features & Benefits of Hydrogen-Terminated Silicone Oil LC-HT3K-20K

  • The molecular structure is regular, and after cross-linking, a uniform elastic network is formed, resulting in stable mechanical properties and high transparency of the product

  • Only the two ends of the molecule contain active hydrogen, the functionality is controllable, the crosslinking reaction is smooth, and it is not easy to produce side reactions.

  • Excellent heat resistance, cold resistance, weather resistance, and oxidation resistance, with no yellowing or brittle cracking after long-term use

  • Low surface tension, good wettability, easy penetration and film formation, moderate adhesion to substrate

  • The Si-H bond has high reactivity and can quickly crosslink with vinyl compounds under low temperature and solvent-free conditions.

  • Strong chemical inertness, good compatibility with most organic resins and fillers, not easily delaminated, and not corrosive to metals.

  • Non toxic and odorless, with low volatile matter, it can meet environmental and safety requirements such as food contact and electronic sealing.
