Silicone caulk sealants come from a group of products, which all share a common problem-the use of chemicals. Many people don't realize that in the manufacturing of Silicone caulk sealants, there are ingredients that have been proven to be toxic. Many of the sealants sold in stores are made from petroleum, which is another source of toxins. The use of toxic chemicals is prohibited by law.
Most sealants are made from either rubber or silicone elastomeric compounds. Silicone sealants tend to form excellent adhesion bonds with almost any surface, while other sealants like P.E.T. have excellent adhesive strength and form very good vapor barriers. In terms of high humidity resistance, silicone sealants are about 10 times more effective at preventing condensation than P.E.T. They are also able to prevent moisture from penetrating into the concrete, which makes them excellent for Silicone caulk sealants in high moisture areas like industrial plants and warehouses.
The use of silicone and P.E.T. based sealants are discouraged in the manufacture of sanitary coverings and are not recommended in industrial environments. Silicone and P.E.T. based additives are the main cause of the increased levels of toxins found in our atmosphere. The use of low level P.E.T. additives can prevent mould growth in industrial environments; however they are unable to prevent it completely.
