The sealant is one of those materials without which modern repair is simply not possible. That is why his choice must be approached with a high degree of seriousness. There are several main types of sealants. They are willing to use and the number of components in their composition. As a rule, materials consisting of one component are already ready to work, and those that include two or more elements need to be mixed in given proportions.
Depending on the basis, all sealants are divided into several types. They can be polysulfide, acrylic, urethic, but silicone -based sealants are most widely used. Silicone sealants are universal, as they have a number of important properties: resistance to aggressive environments, weather changes and ultraviolet rays. Their frosts are also appreciated – and thermal resistance. All these unique properties of the sealant are determined by its special composition, which, in addition to silicone rubber, includes amplifiers, increasing strength, fillers, dyes and components that, when vulcanization, turns a lot of pastoral texture into material similar to rubber.
When choosing a particular type of sealant, it is also necessary to take into account in which room and in what conditions it will be applied. For example, in the kitchen and bathroom it is best to use materials that have antifungal properties, but they should not come into contact with food products. If it is supposed to repair the aquarium, then in this case you should choose a tool that has high strength, but at the same time safe for living creatures.
However, when purchasing any type of sealant, it is necessary to check the presence of a certificate from this product, its expiration date, as well as clarify the content of silicone – in a qualitative tool this figure is more than 25 %. Only in this case will the repair will delight the owners for a long time.
