RAL 7043 - Traffic Grey B

What Is RAL 7043 Traffic Grey B Color Gel Coat?

RAL 7043 Traffic Grey B Color Gel Coat is a polyester gel coat precision-formulated to the RAL 7043 Traffic Grey B standard. Gel coat goes into the mold first, before any reinforcement, and becomes the finished outer surface of the part. Because the Traffic Grey B color is in the gel coat resin itself, it is part of the surface permanently rather than a topcoat that can be worn away.

Why Choose RAL 7043 Traffic Grey B Color Gel Coat?

Traffic Grey B is the darker of the two Traffic Grey shades in the RAL standard. It is used on road infrastructure, vehicle components, and safety composite parts where the specification calls for the darker Traffic Grey B rather than the lighter Traffic Grey A. Fibre Glast matches it precisely to the RAL 7043 standard, so the color is consistent and repeatable across production runs. For physical color confirmation before ordering, the #4008-A RAL Color Book has printed swatches of all 188 RAL colors.

What Are the Best Applications for RAL 7043 Traffic Grey B Color Gel Coat?

Road infrastructure composites, vehicle components, and safety equipment where the darker Traffic Grey B specification is required. For open-air repair work, combine with Duratec Hi-Gloss Additive for a tack-free cure.

How Should RAL 7043 Traffic Grey B Color Gel Coat Be Used for Best Results?

RAL 7043 Traffic Grey B Color Gel Coat requires careful film build for best results. Catalyze with #69 MEKP at 1.5% to 2.5% and spray over a properly prepared mold surface. Apply 4 to 5 coats of about 5 mils each, allowing 15 to 20 minutes between coats, building to a total of 20 to 25 mils. The #122-A Gel Coat Thickness Gauge helps keep film build consistent across the part. Thin with #70 Styrene Thinner or Duratec #1039/#1040 as needed for spray viscosity. Coverage is 40 to 80 square feet per gallon. This is a made-to-order color and all sales are final.
