Features
Hydroxyl silicone oil is made by polymerization of siloxane monomers, the molecular silicone materials have hydroxyl groups at both ends. The structural formula is as follows:HO-Si (CH3) 2 O [Si (CH3) 2 O] n Si(CH3)2-OH
Colorless transparent liquid with excellent electrical insulating properties and resistance to high temperature, high flash point, low freezing point, long-term used -50 °C~ +250°C conditions, low the viscosity-temperature coefficient, high compression ratio, low surface tension, hydrophobic moisture resistance, chemical inertness, physiologically inertness.
Specifications:
Appearance : colorless transparent liquid.
Viscosity (25°C, mpa.s): 25~30
Hydroxyl content (%): 8 - 9
Application:
Depending on the hydroxyl content and viscosity, respectively for different industries .
1. Small molecule hydroxyl silicone oil (25 ~ 40cst, hydroxyl content of about 8-9%) is an excellent control agent of silicone rubber, it not only simplifies the process of silicone rubber to improve the processing performance ( reduce heat treatment ) but also increased the transparency of products, improved working conditions, when we use it to alter dihydroxy diphenyl silane .
2. New development applications.
Dosage:
Usually with the curing agent to achieve the crosslinking, it must be fixed by means of a coupling agent for the release paper, generally the curing agent is about 3 to 5% of gum base, the coupling agent is about 0.5 to 1 % of gum base.
Note:
Hydroxyl silicone oil can not be mixed with high temperature water vapor, acid/alkali substances, alkoxysilanes, otherwise there is a tendency curing and viscosity changes.
Packaging and Storage:
1. The product should be stored in airtight plastic bucket clean not in contact with acid, alkali substances;
2. Stored at room temperature and ventilated shade;
3. According to the non -toxic and non-dangerous goods storage and transportation.
