What is the difference between TotalBoat High Performance 2:1 and Traditional 5:1 Epoxy systems?

There are a few main differences that set TotalBoat High Performance 2:1 and Traditional 5:1 Epoxy systems apart, without getting into the chemistry of them.

TotalBoat High Performance 2:1 Epoxy Characteristics:

• Three different hardener speeds: Slow, Medium, Fast
• Should not form surface amine blush when cured
• Very clear, glossy surface
• Easy 2:1 (resin:hardener) mix ratio for all 
• Works well with fillers, thickening agents, colorants
• Good tensile strength, less stiffness, works well with wood substrates because of this
• Common applications: Composite laminating, composite repairs, coating, castings (when applied in step-pouring), bonding, fairing

TotalBoat Traditional 5:1 Epoxy Characteristics

• Fast and Slow hardeners
• Works well with fillers and thickening agents
• Will leave an amine blush on the surface after they have cured
• Higher tensile strength and stiffness than TotalBoat High Performance 2:1 Epoxy
• Mix ratio is 5:1
• Common applications: Composite repair, composite laminating, bonding, structural composites
