How to choose sealant? For the application of building sealant, choose according to its performance characteristics. Below, take a look!

1. Concrete bonding

PC board used on the market is mostly concrete board, so the building sealant should have good adhesion to the coagulant. Due to the characteristics of concrete itself, ordinary sealant is not easy to bond on its surface. The selection of building sealant should consider concrete is a kind of alkaline porous material, release agent used when the release agent remains on the surface of the PC board.

2. Joint displacement

When choosing sealant, its mechanical properties are also very important. In the design should consider the displacement of the joint, determine the width of the joint, is the deformation of sealant in. Within the bounds of tolerance. For 10~ 35mm concrete joints, sealant is generally required to have good displacement capacity and elastic recovery rate, so that it can adapt to joint displacement.

3. Weather resistance

The weather resistance of building sealant will affect its service life, and due to the specific molecular structure of silicone sealant, even at energy. High ultraviolet irradiation is not enough to destroy the structure, the best silicone sealant has good ultraviolet resistance, so that it has obvious advantages in weather resistance.
