Working condition from the

As led by mastic, based on the display of the transition to working condition, delimiting to dry, hardening and non -hardening. Turning mastics pass into working condition from the form of delivery due to chemical reactions of components from each other (in multicomponent compounds) or with the reaction of the mastic personally with air moisture (in one -component). As a result, the mastic is converted into a rubber -like state from the pastry. Uncontacked mastics are extremely viscous masses that are like plasticine by density. These mastics are less durable (from 4 to 7 years) comparing with the rubber -like texture. Drying mastics obtain the desired characteristics solely after disappearing the solvent or water surrounding in their composition. As a result, a significant decrease in the volume of the material occurs, that is, its shrinkage. And remember that the main rule in any construction work is to entrust the case to professionals!
