Hydroxyl silicone oil MY 206
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
Colorless transparent liquid with
excellent electrical insulating properties and resistance to high temperature,
high flash point, low freezing point, long-term used -50 o C ~ +250 o C
conditions, low the viscosity-temperature coefficient, high compression ratio,
low surface tension, hydrophobic moisture resistance, chemical inertness,
Appearance : colorless transparent
Hydroxyl content (%): 8 - 9
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.
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.
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.
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
