Roto-Molding Resins
Quick Overview
RotoMolding Resins are specifically formulated 2-component 100% solids hybrid polyurea-based material designed to produce dimensionally stable, structural hollow part moldings. This material is normally batch-mixed and poured into hollow room-temp mold. Solidification times may be tailored to accommodate large part or intricate moldings. Casting material is normally applied at room temperature. Resins may be colored-tinted as well as durometers may be formulated to range from 60A-75D. Resins may be neat or filled to meet material shrinkage requirements (1% to 0.5% respectively). Material formulations functional operation temperatures may be formulated to range from -20°F to 200°F.

Application Instructions
RotoMold Casting Resins must be mixed thoroughly prior to dispensing into roto-mold. It is very important not to induce air when mixing. Entrapped air will cause bubbles and micro porosity internally and on the exterior surface. For fiberglass molds use hi-temp paste wax. Resins may be dispensed using low pressure static mixer machine equipment. Please call our Technical Support Group or for any questions regarding material, application or direction of use.
