TotalBoat Tropical Hardener has an extra slow cure rate that gives you extra long working time in normal conditions, but also allows ample working time in very warm, humid conditions. At room temperature, its extra slow properties offer twice the working time of our Slow Hardener. Mix Tropical Hardener with TotalBoat Traditional Epoxy Resin (sold separately) for coating, layup & bonding applications. Dries to a clear, amber color (not intended for clear coating).
Choose from two sizes: 10 oz. Group Size A & 42.3 oz. Group Size B packaged to reduce waste, save money, & match the Group Size A & Group Size B Traditional Epoxy Resin container sizes.
Note: Due to the COVID-19 Emergency, we are currently experiencing a shortage of epoxy pumps. Tropical Hardener does not currently come with a dispensing pump.

IMPORTANT: When using the pumps, ONE PUMP of TotalBoat Epoxy Resin is calibrated to mix with ONE PUMP of TotalBoat Tropical Hardener. Prime this pump by pumping until a steady flow of hardener comes out. DO NOT USE THIS PUMP WITH ANY OTHER HARDENERS.
Surface Preparation: All surfaces must be clean, dry, and free of any surface contamination. Light sanding is recommended, followed by an oil-free solvent wipe, or a lint-free rag dampened with isopropyl alcohol or plain water to remove dust.
MEASURING: NOTE: THE MIX RATIO IS DIFFERENT THAN TRADITIONAL TOTALBOAT FAST AND SLOW HARDENERS. There are three ways to measure: (1) Use the calibrated pumps and the measuring is done automatically, (2) BY VOLUME: Measure THREE parts TotalBoat Epoxy RESIN to ONE part TotalBoat Tropical Hardener, or (3) BY WEIGHT: Measure 100A:28B.
MIXING: Mix for 1-2 minutes, then add any desired fillers, if needed. The catalyzing of TotalBoat Epoxy is an exothermic (heat-producing) reaction. The peak exotherm will vary according to ambient temperature and choice of hardener.
Eye/Skin Protection: Wear protective eye wear, suitable gloves, and protective clothing.
NOTE: This container will not come filled to the top. It contains the calibrated amount of product to work in conjunction with the same size resin container.
Always wear protective clothing and equipment to protect your eyes, skin, and lungs when working with TotalBoat Traditional Epoxy Resin and Hardeners. Personal protective clothing should include appropriate gloves, safety glasses or goggles, a proper respirator, and a proper apron or similar protective clothing.
