JP107 Polymer Hydroxyl silicone oil is the organosilicon material
polymerized by siloxane monomer terminated with hydroxyl groups .
Conventionally the hydroxyl silicone oil with viscosity above 1500
mpa.s is called 107silicone sealant/adhesive.
Apart from general functions of hydroxyl silicone oil, this product
possesses the reactivity of hydroxyl group that can be made into
some new material or crosslinked as elastomer(or film body). This
product is colorless transparent liquid with excellent electrical
insulation, high and low temperature resistance,high flash point,
low freezing point,long-term adaption to temperature from -50°C to
250°C, low viscosity-temperature coefficient, high compression
rate, low surface tension, good water repellent and moisture
resistance, chemical inertness, physical inertness.
Excellent waterproof and dustproof performance;
Sealing for various installation of aluminum alloy glass doors and
Sealing for organic glass, polycarbonate.
Excellent weather resistant performance and excellent ageing
Excellent adhesion to most of building materials and excellent
compatibility with other neutral silicone sealants.
Used as main raw material in RTV mold silicone rubber, defoamer and
silicone glass cement.
1. Used as insulating, moisture resistant, anti-shock and heat
resistant perfusion sealing material in radio, electronic
equipment, semiconductor and other electronic components and
2. Used as rubber roller material in automobile and machinery
3. Used as rubber roller material in textile, plastic and printing
4. Caulking sealing material in construction industry.
5. It has excellent mold release performance, particularly suitable
for the manufacture of precision mold and impression materials.
[USAGE AND DOSAGE]
Generally use with curing agent to get crosslinking curing. Used in
release paper, it need coupling agent to fix. The curing agent
accounts 3 to 5 percent of the silicone glue and coupling agent
accounts 0.5 to 1 percent. Most of the cases the silicone glue are
spread on surface of the base material after being mixed by curing
agent and coupling agent in ten times dilution of dissolvent, then
get solidified in ordinary temperature for over 30 minutes or by
heated between 120°C and 150°C for 30 seconds. No dissolvent is
needed in sealant and mould gum. Stir in mixture of curing agent
(varies from single-component to double-component), and 30 to 120
minutes after deaeration it will solidify.
No mixing with acid-base materials, alkoxy silane or high
temperature water vapor, otherwise there is the tendency of curing
and viscosity changes.
