1980 - is the stiffest, highest modulus resin in the group. It is generally used in carbon fiber composites where it's elongation best matches that fiber
2000 - is used in high modulus carbon, aramid and S and/or E fiberglass applications. It's elongation matches well with all of these fibers.
2020 - Is used in composites which require good stiffness and impact strength. This products elongation matches well with fiberglass, natural fiber and synthetic fabrics.
2040 - is our best for impact loads. It's long elongation in most cases make a composite that will be nearly free of the tendency to crack upon impact. It matches well with E glass, synthetic and natural fiber fabrics.
Project 21 Hardeners
Project 21's three hardeners. While the four resins above control the structural qualities of your finished product these hardeners control your processes, i.e, work time, cycle times, work flow, etc.
2100F - Fast hardener with a pot life of 18 minutes and sets in 2 to 3 hours
2100S - Slow hardener with a pot life of 40 minutes and sets in 4-6 hours
2100X - Extra Slow with a 160 minute pot life and sets in approximately 12 to 16 hours.
