Automotive Refinish Coatings

On The Road Again

Automotive Refinish Coatings

As more vehicles crowd the roads and the number of miles traveled increases there is a greater likelihood of a vehicle being damaged either through wear & tear or a collision.  Automotive refinish coatings play a large role in returning damaged vehicles to their former glory and ensuring automobiles remain looking as good as new.  While the market for automotive refinish coatings is expected to grow, there are some key challenges & trends repair shops and coating manufacturers are faced with that must be addressed.

Automotive Refinish Coating Formulation

An important factor for automotive refinish that never changes is customer satisfaction.  One way to ensure satisfaction is with a high quality, fully optimized coating product, and manufacturing a high quality coating starts with the formulation.   Most automotive coating systems consist of three parts: primer, base coat, and top coat.

Primer

Many of the lightweight plastics used in automobiles today are notoriously difficult to adhere to.  Primers are used to prepare a surface for a coating to ensure adequate adhesion. These formulations typically consist of a binder resin, a solvent, and additives to improve wetting & surface area.  The binder resin in a primer system must be able to bond to low energy surfaces and improve surface energy for subsequent coatings.

Basecoat

When most people think of automotive paint they are thinking of a basecoat.  The basecoat is what provides the color to an automotive coating system.  A basecoat formulation consists of a binder resin, pigments or pigment dispersion, solvent, and additives to improve wetting & leveling.  Ensuring maximum pigment wetting and proper pigment orientation is critical to manufacturing a high quality basecoat.

Topcoat

Once the basecoat is applied that beautiful paint job needs to be protected; this is where the topcoat comes into play.  Topcoats or lacquers are applied over a basecoat and are typically hard, glossy coatings that are resistant to moisture, chemicals, UV, abrasion, and temperature.  A typical topcoat formulation consists again of a binder resin, solvent, and wetting / leveling aids.  It is incredibly important that the binder resin for a topcoat provide optimal durability to ensure a long lasting automotive refinish coating system.
