The chemical name is αω,-dihydroxy polydimethylsiloxane, and the hydroxy silicone oil with a viscosity of 2500mpa.S or more is called 107 silicone rubber. In addition to the general properties of methyl silicone oil, this product also has the reactivity of hydroxyl. It can be used to make some new materials or cross-linked into elastomers (or membranes).

This product is a colorless and transparent liquid with excellent electrical insulation and high and low temperature resistance, high flash point, low freezing point, can be used for a long time under the condition of -50ºC~+250ºC, low viscosity-temperature coefficient, high compressibility, surface Low tension, good water and moisture resistance, chemical inertness and physiological inertness.

Dosage:
Generally used with curing agent to achieve cross-linking and curing. When used for release paper, it must be fixed with a coupling agent. Generally, the amount of curing agent accounts for 3 to 5% of the base gum, and the coupling agent accounts for 0.5 to 1 of the base gum. %. In most cases, the base gum is diluted 10 times with a solvent, and then the curing agent and coupling agent are added and mixed uniformly, then coated on the surface of the substrate, and cured at room temperature or by
heating. It takes more than 30 minutes at room temperature, and 30 seconds for heating at 120~150°C. No solvent is needed for sealant and mold gum base. Stir evenly after adding the curing agent (the curing agent is different for one-component and two-component), and it can be cured within 30 to 120 minutes after deaeration.

Precautions:
Do not mix with acid-base substances, alkoxysilanes and water vapor at high temperature, otherwise it will tend to solidify and change viscosity.

Packaging, Storage and Transportation:
Packing: This product is packed in 25 , 50 , 200 plastic drums;,

Storage: This product should be sealed and stored in a ventilated and cool place, and should not be in contact with strong acids and alkalis;

Transportation: Store and transport as non-toxic and non-dangerous goods.
 

 

Application

Use and application:
· Products with medium and high viscosity are used as base glue for paper anti-sticking agent, and the cured film has good anti-sticking effect. Such as label bottom paper, asphalt packaging paper, sealing paper tape bottom paper, decoration paper bottom paper, etc.
· Used in the power and electrical industry, as the main component of insulating paint or as a component of insulators.
· Used as the base rubber and diluent of condensation type room temperature vulcanized silicone rubber, such as the base material of sealant and mold rubber.
· It can be used instead of dimethyl silicone oil and is easy to emulsify.
· Small molecular hydroxy silicone oil (15-30CP, hydroxyl content is about 8%) is an excellent structure control agent for silicone rubber. Using it to replace diphenyldihydroxysilane not only simplifies the processing technology of silicone rubber, but also improves the processing performance (saving To heat treatment), it also increases the transparency of products and improves working conditions.
·Other unfinished and undeveloped applications.

This product can be used in different industries according to the hydroxyl content and viscosity.
