Silicone sealant producing.

Silicone sealant is a liquid form of adhesive. Typically, it looks, feels, and acts like a gel. It has a different chemical make-up from other organic polymer-based adhesives. Unlike other adhesives, silicone keeps its elasticity and stability in both high and low temperatures. Furthermore, silicone sealant is resistant to other chemicals, moisture, and weathering. This makes it less likely to fail when building and repairing objects.
Unlike some adhesives, silicone sealants must cure. Curing silicone basically means letting it dry. Curing silicone isn’t necessarily difficult, but it does require patience. The temperature needs to be between 40°F and 100°F, and there needs to be between 5% and 95% humidity for silicone to cure. It can take as little as 24 hours to cure, or it can take up to several days if the sealant is especially thick.
We are a production and service provider of silicone civil construction sealant, industrial sealant, neutral transparent silicone sealant, neutral color silicone sealant, and special purpose sealant products.
We integrate production, R&D, and sales, and have domestic high-level production equipment and a product R&D center.
Our production technology and quality are at the leading level in the country, with an annual production capacity of 30000 tons.
Our products are sold well in the domestic market and exported to more than 20 countries and regions.

Frequently Asked Questions

Why is the acid sealant used on cement easy to fall off?

Because the application range of different sealants is required, the acidic sealant will produce acetic acid when it is cured, and react with the surface of alkaline materials such as cement, marble, granite, etc., forming a chalky substance that causes the sealant to crack, fall off.

Why do salt-like particles sometimes appear when glass sealant is glued, and some particles will automatically dissolve after curing?

This is a problem with the glass sealant material. Because the cross-linking agent contained in some glues crystallizes in a lower temperature environment, and after being punched out, you will see grains the size of salt grains, and the crystals will slowly melt as the temperature rises, so after curing The granular form will dissolve automatically again.

This situation is mainly due to the relatively large impact of low temperatures.

After the neutral variegated sealant dries, there are powdery things on the surface. What causes it?

Generally, there are the following situations:
① Defects in the raw material of the sealant;
② uneven mixing of raw materials;
③ Due to the influence of the construction environment, this situation will occur when more dust is adsorbed on the surface of the sealant. (So the construction environment is also an important factor).

What is the reason why some single-component glass sealants have not been fully cured after 7 days after being applied to the glass?

① The glue is too thick and the curing speed is slow;
② Influenced by the construction environment, low temperature or no air circulation;
③ The sealant has expired;
④ After curing, the colloid itself is soft and feels impermeable.

What causes the neutral transparent sealant to turn yellow?

The yellowing of neutral transparent sealant is a defect in the sealant itself, which is mainly caused by the crosslinking agent and tackifier in the neutral glue. The reason is that these two raw materials have "amine groups", which very easy to cause Yellowing, many imported brand-name glass sealants also turn yellow because of this. In addition, if the neutral transparent glue is used together with the acid glass glue, it may also cause the neutral glue to turn yellow after curing; it may also be caused by the long storage time of the glue or the reaction between the glue and the substrate.

How to clean the glass sealant on your hands and glass?

After the glass sealant is cured, it will not stick to your hands, just rub your hands a few times; if the glass sealant sticks to your hands or glass, use a clean cloth to dip a little acetone, xylene, or No. 120 solvent oil before curing Clean up; when purchasing a professional cleaning solvent for glass sealant, you need to learn how to use it from professionals; if the glass sealant on the glass has solidified, you can use a blade to scrape it off.

What is Silicone Sealant

Silicone sealant is a paste made of polydimethylsiloxane as the main raw material, supplemented with a crosslinking agent, filler, plasticizer, coupling agent, and catalyst in a vacuum state. Reacts with water in the air and cures to form elastic silicone rubber.
