Is silicone glue toxic? Recently, many users found the official website of CoolThermo silica gel through Google search for CoolThermo silicone glue, and consulted a lot of questions. Is your silicone glue environmentally safe?
As we all know, silica gel is a new type of environmentally friendly and non-toxic material. What is irreplaceable in silicone products is silicone rubber adhesive, that is, silicone glue. Whether the silicone glue is toxic or not, we have to analyze the principle, mechanism of action of silicone glue and the evaluation criteria for the toxicity of the adhesive.
Analysis of the principle of silicone glue
Silica gel, also known as silicic acid gel, is a highly active adsorption material and is an amorphous substance. Silica gel components Silicone based glue, silicon dioxide, calcium carbonate, curing agent, etc. The main component is silicon dioxide, which is chemically stable and non-flammable. Silica gel can be said to play an increasingly important role in our lives, but in our daily use of silica gel, we are faced with the adhesion of silica gel and silica gel, silica gel and plastic products, silica gel and metal and other materials, which requires us It has a mixture that makes it stick together, which is silicone glue.
Introduction to the mechanism of action of silicone glue
Silica gel glue is a highly active adsorption material, which is an amorphous substance with organosilicon polymer compound as the main component. Silicone glue is a type of adhesive in silicone rubber that is used for bonding silicone and silicone, silicone and similar plastics. It is cured by contacting water molecules on the surface of the bonded or sealed object or water molecules in the air. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. Various types of silicone glues form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silicone glue determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.
What is the standard for judging the toxicity of silicone glue?
During the working process of the adhesive, some benzene substances are volatilized, resulting in poor breathing or skin allergies. This is a toxic standard that all users cannot accept. The silicone glue is made of new raw materials, which is environmentally friendly and healthy, and does not contain any toxic substances.
It has been proved by authoritative testing that silicone glue is a solvent-free product, does not contain any volatile substances, will not affect human health and will not pollute the environment.
When the silicone adhesive is cured, it will not volatilize formaldehyde and benzene. All raw materials have passed SGS environmental protection testing and are food-grade materials. In short, the raw material of silicone glue has reached the level that can be imported. How can it contain toxic substances?
If you choose a solvent-based silicone rubber adhesive, it is important that it has undergone advanced medical-grade testing and SGS environmental protection testing, and it can also be used. In order to avoid potential safety hazards, it is recommended to choose a paste-like adhesive, which has no volatiles and no worries.
Silicone glue adhesive is not a dangerous product, but a chemical, which may worry many users; for all users, choosing a healthy and environmentally friendly silicone glue adhesive will not harm the body of the staff, Will not pollute the environment. Don’t buy products without environmental testing to save some money, be careful to be deceived.
