Combined Synopsis/Solicitation NAICS 325211

3 complete drum kits of 870 slow Black urethane casting resin and 1 complete drum kit of 870 slow Tan - These urethane kits are semi-rigid plastic with some flexibility that is strong and tough. Originally developed for high impact tooling, this product also offers abrasion and chemical resistance. It is ideal for a variety of industrial applications and fabrication of military training aids. Each of the three kits consists of two 55-gallon drums (Part A and Part B). The mixed resin is low in viscosity and does not require vacuum degassing.
