Non-crystalline polymer rubber accelerators elastomer material, the paint coating on the impact of the construction in the following areas:
1, the surface tension of rubber is non-polar materials, the surface energy is low, especially polyolefin rubber, silicone rubber and fluorine rubber, are difficult to attach material, the adhesion of paint disadvantage.
2, easy swell or dissolve the Rubber Auxiliary in most organic solvents or oils, are swelling or dissolution phenomena in the paint in the construction process, due to swelling and solvent evaporation resulting from the contraction of the volume shrinkage stress, will trigger a series of paint defects, even cause the coating peeling off.
3, the elastic modulus of rubber as the elastic body, when the deformation will be generated by external forces, mainly compression and tensile deformation, resulting in a corresponding stress, so the elastic modulus of the coating to the substrate with the rubber match, otherwise in the deformation of the stress generated in the process will destroy the coating adhesion.
4, the electrical resistance of rubber chemical structure determine its resistance greatly, generally resistivity, has a strong static electricity, but carbon black reinforcement of the products, the surface resistance and volume resistance can decrease significantly, before painting rubber composition has sufficient understanding to help correct choice of the appropriate treatment and painting.
