Georgia-Pacific Chemicals products are used around the globe as a primary component of FRP COMPOSITES.

FRP composites are used to replace steel, aluminum, and wood in a wide range of applications. Composites offer numerous advantages over other materials – lower density, lighter weight, better corrosion resistance, strength, and durability. Composites’ inherent fire resistance, strength, and ability to withstand high temperature environments with less weight than those materials have made them the product of choice for fire resistant piping, mining ventilation systems, and armored vehicles. In public transportation, they are used in aircraft interiors, fire resistant railcar and bus parts, passenger decking and walkways.

Our phenolic novolac resins are used as curing agents for epoxy resins and as cure accelerators that promote rapid cure in resins for use in FRP composite applications.

Our portfolio includes products designed for the following processes:

PULTRUSION

  • Can process on traditional polyester pultrusion equipment
  • Styrene-free
  • Thermally cured

SHEET AND BULK MOLDING COMPOUNDS (SMC/BMC)

  • Resistance to hydrocarbon and chlorinated solvents
  • Viscosity, processing and cure properties that can avoid special processing or equipment adjustments

HAND LAY-UP AND RESIN TRANSFER MOLDING (RTM)

  • Parts made from many GP® resins meet requirements of United States, British and International
    Maritime Organization Standard Fire Tests

HONEYCOMB AND PREPREG

  • Resins for Nomex® and Kevlar® honeycomb, glass and carbon fiber prepregs
  • Solvent-borne and waterborne resins
  • Parts made from many GP resins meet requirements of United States Military Specification MIL-R-9299C and MIL-
    DTL-64154B

FILAMENT WINDING

  • Latent catalysts to produce a pot life equal to that of a polyester mix while maintaining cure speed
  • Typical resin cure temperatures are 65°C to 95°C
  • After curing, pipes demonstrate strength, dimensional stability, and glass transition temperature (Tg) from
    120°C to 220°C. Higher Tg is possible

The products below represent many of our off-the-shelf products. Contact us to identify the product appropriate for your specific application. Some of our products are used with resin systems that include a GP catalyst as a base accelerator to improve cure speed.

§ Contact Georgia-Pacific Chemicals for your specific solvent requirements. Georgia-Pacific Chemicals recommends the use of a catalyst with many of our resins. Parts characteristics are contingent on proper application of the GP® resins. These products are available in drum and bulk packaging. Resins and catalysts should be used in areas with good ventilation. Resins should be stored at temperatures at or below 40°F (5°C). Catalysts should be stored at 20 – 25°C, lower temperature storage can cause crystallization of the catalyst. Prior to use, the resin should be brought to room temperature. As with any resin/acid system, precise and thorough mixing of the resin and catalyst mixture is essential to achieve uniform cure and optimum quality.
