ZQ457 silicone
Features
ZQ457 is a flat sealant specially designed for automotive engines and other general industrial production where high temperature resistance conditions are required. It is a one-component, room temperature vulcanized neutral silicone sealant. It has very good temperature resistance and can seal instantly. Great gap.
Main features
1. One-component, RTV room temperature vulcanization, neutral deoxime type silicone rubber, no corrosive effect on the material after curing, no irritating odor, no various gaskets.
2. Good oil resistance, temperature resistance and shock resistance.
3. Keep a permanent sealed state in the range of -50~260℃.
4. Good elongation.
Basic use
Replace all kinds of rubber pads, asbestos pads, cork pads and paper pads, and seal the starting gearboxes, axles and other joint surfaces of various automobiles, motorcycles, ships and various mechanical equipment to prevent water and air leakage , Oil spill.

Use process
1. Remove oil and dust on the surface to be adhered, and keep the adhesive surface clean and dry.
2. Apply glue to the surface to be bonded and coat it into a continuous rubber ring.
3. Fasten with bolts as usual.
4. After the glue is applied, do not put it into use immediately. After it has cured completely (≧24h), an elastic shock-proof sealing gasket can be formed to seal and prevent leakage.
Precautions
1. The glue has a volatile odor, please pay attention to ventilation when using it.
2. Avoid long-term skin contact with sealant. If unvulcanized rubber gets into eyes by mistake, rinse immediately with water or see a doctor.
3. Keep out of children's reach and not ingest.
4. The remaining rubber material is strictly sealed. Store in a cool, ventilated and dry place.
5. Executive standard: Q/320481 MTH002-2012
