K-FLEX® XM-337

K-FLEX® XM-337 is an aliphatic saturated polyester diol modifier resin designed to provide increased toughness and chemical resistance for solvent-based and high solids systems. It is recommended for use in 1 and 2 component polyurethanes, and blocked isocyanate systems. Benefits include low color, UV durability, high hardness, high impact resistance, abrasion resistance and overall increased toughness.

Storage/Shelf Life
  • Store in a cool, dry location. On storage near ambient temperature, K-FLEX XM337 may form a crystalline haze. Warming to 60°C for a short period of time will clarify the product.
  • Minimum of 24 months from date of manufacture, when stored in the original container at ambient conditions.
