When exposed to moisture freshly coated with a film material for example, 5-10 minutes (in Depending on the product) at room temperature and 50% relative humidity. Any tooling should be completed before the film is formed. The surface is easily treated with a spatula. Using primers For maximum adhesion is recommended to use a primer Dow Corning. After cleaning solvent roller, brush or spray a thin layer of primer is Dow Corning. At normal room temperature and humidity conditions (room temperature, relative humidity 50%) of primer should dry up in the air from 5 to 30 minutes.

Primer hardens on contact with atmospheric moisture in dry air requires more drying time. To use to determine the required drying time for concrete surfaces. The primer, which was subjected to excessive hardening ceases to contribute to increased adhesion. As a rule, avoid timing more than 6 hours of drying at normal temperature and humidity. After the curing time of film formation hardening extends inward from the surface. For 24 hours (at room temperature and 50% relative humidity) gley / Sealant Dow Corning undergo curing to a depth of about 3 mm. Very deep seams, especially with the limited access of atmospheric moisture is required to fully cure longer. Curing time increases with low humidity levels.

Because sealants cure by reaction with atmospheric moisture, keep the containers thoroughly clogged with them, when not in use. At the tip of the tube or cartridge during storage tube can be formed from hardened material. This cap can be easily removed and does not affect the rest of the product. Compatibility Some adhesives / sealants Dow Corning at the time of curing a small isolated acetic acid. It can corrode some metal parts or surfaces, especially through direct contact or when the cure is complete in a confined space that does not allow side- products cure escape. Issues of health safety and environmental impact to support customers in the security of Dow Corning's products in each region has an extensive Product (Product Stewardship) and a group of experts in the field of product safety and compliance (PS & RC).
