The effect of rubber material on paint and coating construction performance

Rubber material is a non -crystallized polymer elastic material, and its impact on paint and coating construction is mainly reflected in the following aspects

1. Surface tension Small rubber belongs to non -polar materials, with low surface energy, especially polyolefin rubber, silicone rubber and fluorine rubber, which is difficult to attach materials, which is not good for the adhesion of the paint.

2. Most of the organic solvents or oils in the rubber or dissolving rubber have swelling or dissolving. During the painting construction, the shrinkage stress caused by the volume caused by the swelling and the volatilization of the solvent will cause a series of paint defects, or even Causes the coating to peel off.

3. The elastic modulus large rubber is used as an elastic body. When it is subject to external forces, it will cause variable, mainly due to compression, deformation and stretching deformation, thereby generating corresponding stress. Therefore The stress generated during the deformation process will destroy the adhesion of the coating.

4. The chemical structure of the resistance large rubber determines that its resistance is large, the general resistivity, and has a strong static electrostatic. The composition of rubber products has enough understanding, which helps to correctly choose appropriate treatment methods and paint.
