Posted by sere on February 10th, 2020

Silicone sealant is polydimethylsiloxane as the main raw material, supplemented by crosslinking agent, filler, plasticizer, coupling agent, catalyst mixed in the vacuum state of paste, at room temperature through the reaction with water in the air, solidified to form elastic silicone rubber.

Silicone sealants are used as follows:

1. Silicone sealant can be easily shot out of the bottle with a glue gun. Without a silicone gun, consider cutting the bottle with a blade and then lather with a spatula or wood chip. Can use adhesive paper to cover the periphery, avoid smearing other places and make it beautiful after curing, but after coating, must be removed before the formation of the outer skin.

2. The curing process of silicone sealant is developed from the surface to the inside. The drying time and curing time of silicone sealant with different characteristics are not the same.

3. The curing time of silicone sealant increases with the increase of adhesive thickness. For example, the acidic silicone sealant with 12mm thickness may take 3-4 days to solidify, but within about 24 hours, the outer layer of 3mm has been solidified.

4. Completely wipe the toilet and the surface of the floor to remove oil, then evenly apply the silicone sealant to the surface of the ready surface, and then squeeze the other side with enough force to squeeze the air. Wait for the silicone sealant to solidify, but be careful not to squeeze the silicone sealant.

5. Silicone sealant before curing can be removed with a cloth or paper towel, after curing must be scraped off with a scraper or xylene, acetone and other solvents scrub.

6. Silicone sealant in the curing process will release irritant gas, the eyes and respiratory tract have irritant effect. Therefore, this product should be used in a well-ventilated environment to avoid contact with eyes or skin for a long time (after use, wash hands before eating or smoking). Keep out of reach of children; Construction site should be well ventilated; In case of accidental splash into eyes, rinse with water and seek medical advice immediately. The silicone sealant is completely cured without any danger.

7. Before use, carefully read the correct construction method and use of silicone sealant, and pay attention to the instructions on safe use and health hazards.
