Extremely fast wet out and Roll out, Moderate trim time, High Strength, Corrosive resistance. MEKP HARDENER Included. Item: FL050330123210IR1G
Isophthalic (Iso) resins are a step above Ortho resins, and are better suited for corrosion environments, elevated service temperatures, and have greater mechanical properties. Iso resins have between 42% and 50% styrene because the higher molecular weight more solvent is required to create a workable viscosity. Iso’s better properties do bring higher cost as compared to Ortho Resins.
Isophthalic ( iso ) resins are higher grade resins in that the molecular structure is denser. It is a special raw material utilized in corrosion resistant and/or premium grade polyester resins. These resins will exhibit a higher heat distortion temperature, higher strength, greater flexibility and are more waterproof than orthophthalic resins
Orca 301 is pre-promoted for curing at room temperature with the addition of methyl ethyl ketone peroxide (MEKP) initiator. Orca 301 is designed to be used with both the spray-up and hand lay application techniquse.
