Characteristics and Uses:
1, one-component silicone adhesive sealant, neutral, single-component, room temperature vulcanized silicone rubber. Free of such products than ordinary silicone rubber pad has better oil resistance, mainly for higher and other electronic pump seal.
2, the product has good acid and alkali, anti-aging, anti-UV, solvent free, non-polluting, non-corrosive, easy to use and other characteristics, electrical performance.
3, glass, ceramics, various metals and rubber-like material has good adhesive properties, high and low temperature performance at -60 ℃ ~ 200 ℃ temperature range can maintain good physical and chemical properties.
4, the electronics industry, household appliances industry, automotive industry, high-voltage substation equipment such as good bonding, sealing, insulation and coating materials, fixed, from the shockproof, waterproof, moisture-proof, leak-proof and anti-sparking, anti-arc and so on .

Main purpose of such products than ordinary silicone rubber pad free more superior oil resistance, mainly for higher and other electronic pump seal.
Usage:
1, in order to obtain the best sealing effect, the surface components to be sealed should be clean, dry and free of impurities, oil or other stains, the best use of anhydrous alcohol or acetone wipe clean.
2, according to the need to cut the beak size, the rubber hose out from the direct bonding glue, glue the amount of mortar and joints on both sides should make adequate contact area.
3, in a short time after glue repair is completed;
4, 12 to 24 hours at room temperature, the absorption of trace moisture in the air and self-curing. If the adhesive thickness and adhesive surface to extend the curing time for big, otherwise short, the longer storage time after bonding adhesive, the better. Temperature components can be cured at room temperature, placed in -50 ℃ ~ 150 ℃, high humidity situations bake 4 to 12 hours, bonding better.
5, after opening as a run out, time has not run out, hose tightly, avoid contact with moisture and air, save for the next use. Re-use, squeeze out the part has been cured, you can continue to use.
Note:
1, after use, tighten the container lid to prevent air contact.
2, this series is non-toxic, but should avoid entering the mouth of the eye, if it accidentally touches the eyes or skin, rinse immediately with water and medical treatment.
3, well-ventilated place at the FDA.
Packaging, storage and transportation:
1,300 g / support.
2, stored at 25 ℃ under dry, cool, ventilated place, shelf life of six months, away from children.
3, the product is solvent-free products, non-dangerous goods storage and transportation.
