PoolKemie Resin PU 087 Casting Polyurethane system
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Introduction: Two component odorless polyurethane system with separate filler. The filler can be added in the suggested or in a different ratio depending on the application and on the required thickness of the casting. Very good detail reproduction, fast cure, low exothermic reaction, low shrinkage. The use of AL 3-H filler (mix ratio 100:100:150) allows production of components with lower specific weight.

Application: Foundry patterns, copy models, negatives, fast reproductions. Prototypes, short runs of casting components. Vacuum thermoforming tooling.

Component A: PU 087
Component B: PUH 887
Component C: AL 3-H
