HOW silicone sealant dries

How dry silicone sealant

Silicone Sealant is a special composition of the building, which is filled with mounting slots.

The main purpose of the sealant - design protection from external destructive influences and pasting multiple surfaces together.

Advantages of the sealant based on silicone

Silicone sealants have goodwater resistance, elasticity of the composition, excellent adhesion when applied to most materials, heat resistance and cold resistance. In addition, they are resistant to solar ultraviolet radiation and aggressive chemical compounds. Silicone sealants are transparent, almost invisible on the surface and do not violate the integrity of aesthetic products.

Sealants are divided into types, designed for outdoor and indoor applications, as well as for work in areas with high humidity.

Also have their differences and components included inpart silicone sealants, which are not in the least affect their speed of drying. To improve the adhesive properties of the sealant is necessary to prepare a pre-treated surface. Otherwise silicone sealant can dry very likely separate from that ruin the work.

How much sealant dries

Approximate drying times for eachsilicone sealant specified by the manufacturer on the packaging. Typically, the sealant hardens within 15-20 minutes, after which begins the process of complete solidification, which occurs at a speed of 2 millimeters per day. The chemical composition they are divided into acid and neutral. Acid sealants are more low price, but they can not be applied to the metal - they cause corrosion on them. Acidic adhesives used for glass, ceramics, wood and polycarbonate. When applied, they emit a distinct odor of vinegar and dry for 4-6 hours.

An exception to the acidic sealants are stainless steel and aluminum neonadirovanny.

Neutral sealants are suitable for anysurface exhibit superior performance properties and relatively high cost. After the application of neutral silicone sealants harden completely during the day at + 5-40 degrees. At the rate of drying agents affect humidity, ambient temperature and the thickness of its application. Calculate the dry period of a silicone sealant in hot conditions can be with the help of simple mathematical manipulations. For this purpose it is necessary to multiply the average length of the solidification thickness under normal conditions by a factor of K = 1.5-2.
