Description of low modulus neutral cure silicone

SATOP® 683 is a one-component, neutral silicone sealant, medium viscosity, medium modulus, high strength, moisture curing type high temperature resistant silicone sealant, Cross-link curing by absorbing moisture in the air in room temperature. After curing, it forms a permanent silicone elastomer with cold resistance, heat resistance and corrosion resistance. Can work under 270 ℃ high temperature for a long time,excellent weather resistance, anti-aging, uv resistance, ozone resistance, long service life.

Typical application of low modulus neutral cure silicone

SATOP® 683 has excellent high temperature resistance. Suitable for bonding and sealing at temperatures up to 270℃. Widely used in automobile manufacturing and engineering machinery industry; bonding and sealing between bodywork sheet metal and sheet metal.

USE of low modulus neutral cure silicone

  1. Cut nozzle to give the required angle and bead size,Pierce the membrane at the top of the cartridge and screw on the nozzle.Place the cartridge in an applicator gun and squeeze the trigger with equal strength
  2. Ensure that the sealant is in good contact with the bonded surface, please modify before surface curing. Once the package is opened, it must be used up in arelatively short time.

Attention of operation of low modulus neutral cure silicone

  1. Do not contact the uncured sealant products with food and cosmetics;please use suitable industrial liquid soap and water to  
  2. clean Immediately when hands and exposed skin touch sealant. If sealant is not carefully entered into the eye, rinse immediately with plenty of water and consult the doctor. Put the product in a place where children can’t touch it.
  3. Uncured SATOP® 681 can be removed from the tools or equipment with appropriate solvents.If sealant has been solidified, it can be removed using a scraper or other mechanical device.
