Norsodyne S 70361 TA (44281) Isophthalic Resin
Unsaturated Polyester Resin

Isophthalic (iso) resins are higher grade resins than ortho 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. These resins can be used for moderate corrosion resistance applications to a maximum temperature of 180° F. They exhibit good resistance to water, acids, weak bases, and hydrocarbons such as gasoline and oil.Applications: tanks, pipes, tooling, and others requiring high-strength retention, corrosion resistance and durability. Isophthalic polyester resin is now becoming the preferred material in industries such as marine where its superior water resistance is desirable.
Medium activity methylethyl ketone peroxide (MEKP) is the recommended catalyst at an addition level of 1.5% by weight to ensure sufficient cure at room temperature.
