TotalBoat 3:1 Tropical Epoxy Gallon Kit

Tropical Extra Slow Epoxy Kits


Extra slow-curing Tropical Epoxy gives you extra long working time in normal conditions, but also provides adequate working time in very warm, humid conditions. Kits contain resin and hardener.

Extra long pot life and working time give you more time to do the job right

TotalBoat Tropical Epoxy Kits give you more time to work before the resin kicks, which is great when you’re coating large areas, covering a lot of joints, or assembling parts and need more time than a regular or slow cure rate epoxy provides. In fact, TotalBoat Tropical Kits give you twice the working time (46 minutes) at room temperature as our TotalBoat Slow Epoxy Kits (20 minutes).

So whether you’re completing larger, more intricate repairs, doing a deck job, glassing a hull, or need more time to prepare a T-Top hardtop for vacuum bagging, our extra slow cure TotalBoat Tropical Epoxy Kits offer the most desired working properties in normal to very warm temperatures, without heating up or tacking up on you.

Three easy ways to measure

  • By Volume: Measure THREE parts TotalBoat Traditional Epoxy Resin to ONE part TotalBoat Tropical Hardener
  • By Pumps: Use the TotalBoat 3:1 Epoxy Pumps (sold separately) to dispense the resin and hardener in the precise proportions, by volume. All you have to do is apply one full stroke of the hardener pump for every one full stroke of the resin pump. The 3:1 mix ratio is preset and is required for a proper cure.
  • By Weight: Measure 100A:28B

After measuring, stir well for about two minutes to combine thoroughly, before adding fillers or applying.


  • Application: Brush, roller, or syringe; can also be poured and spread with an epoxy spreader
  • Application temperature, RH: 70-105°F, 0-90% RH
  • Pot life @ 75°F (150g mass, minimum): 46 minutes
  • Work life @ 75°F (thin film): 3-4 hours
  • Set time @ 75°F (thin film): 20-24 hours
  • Cure time @ 75°F (thin film): 4-7 days
