III. The inorganic substrate of titanate coupling agent is often affected by a layer of water adsorbed on the surface, which is similar to silane coupling agent.
The film and substrate can form hydrogen bond and chemical bond through mechanical combination and physical adsorption, and can be combined by mutual diffusion. The adhesion produced by these actions determines the adhesion between the paint film and the substrate.
Vinyl Resin for PVC gusset plate, Providing the adhesion force between PVC printing and PVC substrate Initial viscosity higher and fastness stronger.
