Project 21 System

Resin Research Project 21 System is a bisphenol A resin based epoxy resin, modified cycloaliphatic amine curing agent system designed primarily for marine, transportation, architectural and general composite use. Special features of this system include medium viscosity, non-blushing characteristics, low vapor, excellent color, high gloss, excellent resistance to water vapor pressure, excellent U.V. stability and high strength.

physical state
medium viscosity water white to pale yellow liquid

storage life
At least 12 months in sealed containers at ambient temperatures.

typical properties
Color (Gardner) 1-3

Applications
Marine, transportation, architectural, and general composites, surf and sailboards, hand lay up applications, coatings

Composite Pro System

Resin Research Composite Pro is a bisphenol A resin based epoxy resin, modified cycloaliphatic amine curing agent system designed primarily for marine, transportation, architectural, and general composite use. Special features of this system include low viscosity, non-blushing characteristics, low vapor, excellent color, high gloss, excellent resistance to water vapor pressure, excellent U.V. stability and high strength.  It's low viscosity facilitates easy wetting of fabric intensive laminates in both hand lay up and infusion.
