Plural Component Coatings

A Fast-Drying Long-Lasting Means of Surface Coating

Plural Component Coating refers to a mobile pump system that combines high-solid materials such as epoxy, polyurethane and/or polyurea in optimal preset ratios when applied to a surface. The protective coatings industry has trended towards using this method of applying coatings due to it’s formulations being less solvent, thus reducing volatile organic compounds (VOC’s) that can harm the environment.

This method of coating is ideal in marine and industrial applications where the result is a fast drying incredibly strong and long-lasting finish. Plural component coating systems have become a necessity for many projects where project turn-around time is critical – especially in cases of marine or naval vessels requiring short return-to-service cycles and some industrial projects where extended downtime is not an option.

The technology for our plural component sprayers have advanced greatly over the last decade to offering ratio assurance and even auto-shutdowns if they detect that the mix is off ratio.

Advanced Marine Preservation has extensive experience with plural component application techniques with a staff of well-trained and safety conscious technicians who have the expertise to know the best application to apply to your given marine or industrial coating requirement.  Contact us today to find out more.

Types of Plural Component Coating Applications

This form of coating application, also referred to as reactive-cure coatings, handle three basic combinations of materials that are employed based on the applicator’s expertise for the environmental conditions and the material being applied to.

  • Epoxy: A combination of mixing a base (resin or epoxy) with an activator (catalyst, hardener, or converter). This method offers tough corrosion protection that can be sprayed wet-on-wet and are typically used in primer applications providing strong chemical resistance.
  • Polyurethane: A combination of mixing an isocyanate with a polyol resin. Ideal for fast-setting coating or finish requirements. Polyurethanes provide a strong high quality finish ideal for handling harsh environmental and corrosive conditions providing strong resistance to chemicals, as well. Typically used over a primer and a topcoat in direct-to-metal applications.
  • Polyurea: A combination of mixing an isocyanate with an amine resin. This is also a fast setting finish ideal for applications where environmental conditions are a factor.
  • NISO: A non-isocyanate based application with a significantly longer durability lifespan and minimizes material waste. Also ideal for corrosive and harsh weather conditions as well as being chemical resistant.
