Paint Film Layers for Repair (Ex.)

Automotive paint finishes require multiples layers of coatings, each with different performance criteria, to achieve the required performance and durability levels.

Rust Prevention:
Rust prevention performance is crucial to the undercoat (putty, primer-surfacer, etc.) that is applied directly to the steel surface.

Filling:
Used to fill dents in the damaged bodywork, sanding scratches and pin holes in the undercoat.

Absorption Prevention (Sealing):
Undercoating materials often have many tiny holes. When the top coat is applied directly over those porous materials, those holes will absorb the wet paint and the top coat will lose its luster. To protect the top coat from absorption, a sealer must be applied before the topcoats.

Luster:
When applied properly, paint gives the color, luster and smoothness to the surface. In addition, all these elements will be very durable.

Adhesiveness:
The base metal or the undercoat must firmly hold the new coat of paint to prevent peeling away from each other.

Workability:
The ease of handling and work speed of the paint finish processes.
