KY-958 Non-toxic, Non-corrosion Single Component Condensed Heat Conduction Silicone Rubbers
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.
