Talking about the Use Method and Principle Application of pp Treatment Agent [Dry Goods]]

1.pp surface treatment agent can be directly sprayed on pp parts, generally as long as the cross spray gun can be used, and the pp parts after construction can be sprayed with paint after drying.

2. For small or complex shape of pp plastic parts, the workpiece can be directly invaded into pp water, after taking out the self-drying after spraying paint

3. If the PP piece after spraying can be baked, the adhesion of the coating film to the substrate is better.

pp treatment agent is widely used in daily necessities, car pp bumper, motorcycle pp guard plate, mirror, toys and other coating.

PP treatment agent is hydroxy chlorinated polypropylene copolymer, which is applied to PP material, modified PP material, miscellaneous material and other surface spraying processes. It can modify the wettability and surface adhesion of PP substrate and combine with each other by forming a layer of film between the substrate and paint. Promote the interlayer adhesion between paint and pp material to form a firm coating, so as to solve the poor adhesion caused by spraying paint and other undesirable phenomena.

pp substrate is to improve the adhesion of the upper coating through flame or arc treatment. However, the equipment cost is relatively high and the operation is inconvenient. Using pp plastic treatment agent as primer can not only improve the adhesion of paint rain pp substrate, form good interlayer adhesion, but also improve the coating. Water resistance and heat resistance of ink.
