Gel Coat Spray System

Complete Gel Coat Spray System, with spray gun and heater system included.

Applying a gel coat is the first step in most open- and closed-mold processes. Gel coat is a highly pigmented form of unsaturated polyester resin. When it is catalyzed with MEKP (methyl ethyl ketone peroxide), it yields a very durable, aesthetically-pleasing finish. The surface finish can range from textured to a class A finish as found on automobiles.

Gel coat can be pigmented to the desired product color or the de-molded product can be post-painted. Gel coat is sprayed in multiple passes to achieve a 15 to 25 mil thickness. Gel coat alone does not have the structural strength to be removed from the mold or to be used as a final product, so another material must be added for reinforcement. This second step in the process is called lamination.

The RS External Mix Gel Coat System includes the following: Gel Coat Gun with Dispense Tip CST521, Material Pump Assembly, 13:1, SST Catalyst Pump Assembly (1-3%), Air Panel Assembly, Material Hose Assembly (25 foot length), Heating System, Cart w/Castors and User Manual.

Gel Coat Spray Gun

Spray Gun Included

  • Quick-disconnect front end reduces maintenance time and increases uptime
  • Unique needle clamp design eliminates need to adjust needle setting after routine service
  • Delivers superior spray pattern
  • Promotes a healthier work environment due to less overspray

Inline Heater

Inline Heater included

Maintain a consistent gel coat temperature for better control, better spray consistency and superior results. Generally, gel coat sprayed at a constant temperature between 68 - 72 degrees Fahrenheit (20 - 22 degrees Celsius) produces superior results, and this included inline heater provides user-selectable temperature control of gel coat temperature.

  • Variable heating levels for consistent viscosity control
  • Approved for hazardous locations
  • 7250 psi (500 bar) maximum working pressure
