Non toxic Single Component Condensed Heat Conduction Liquid Silicone Rubber for lamps
1. Product characteristics
KY-958 silicone sealant is one kind of single component condensed heat conduction silicone rubber, which is made from basis polymer, filler, adjuvant and curing agent.
1) Curing under room temperature, non-toxic, non-corrosion
2) Excellent resistance to cold and heat temperature.
3) Excellent electricity insulating property, resistance to electric arc, corona shock and shock, long-term protection to electrical equipment.
4) Good ability of water proof, ozone resistance and weathering aging.
5) Outstanding adhesive bonding with glass,aluminium,carton steel and copper material.
6) Good heat-conducting property
2. Application
1) can be widely used for any heat dissipation position of electrical components,
2) for the heat dissipation of any high-powder lamps and lanterns.

4. Color of product
1) the color can be done according to client’s demand.
5. Package
1) Packed in 300ML/100ML with tube,
2) the package way can be done according to client’s demand.
6. Usage and dosage
1) in order to gain the best sealing effection, the surface of the potting surface should be clean, dry and without any oil and moisture.
2) potting the sealant as the closed sealant tree lace on the surface of the products.
3) closing the sealant and remove the extrusived rubber.
4) Isolating with air if the sealant hasn’t used up in one time. When you using it again, please edge out the cured sealant.
7. Product packaging and storage:
1) This product should be stored in a cool and drying place under the temperature of 4℃～27℃, the shelf life is 9 monthes from the production date.
2) The products according to the non-dangerous goods storage and transportation.
8. Matters to be attention
1) Stored in ventilated place, because the silicone rubber can’t be cured without the moisture in the air,
2) the surface of the potting products should be non-oil, non-frosting or non-moist.
3) can’t be used as construction rubber,
4) can’t be used as high pressure sealing rubber.
