AbForm Ekopur-85A

Description

Impression Ekopur Shore 85A
Two-component polyurethane system for casting applications – professional resin + hardener

The offered product is a high-quality, solvent-free two-component casting system based on polyurethane resin and hardener. The material has been specially developed for the production of technical castings, elastic moulds and components with high mechanical strength and dimensional stability.

Thanks to the optimal hardness (80-85 Shore A), the low shrinkage (<0.5%) and the excellent detail reproduction, it is suitable for industrial applications as well as for model making and artistic works.

Scope

✔ Production of elastic moulds for architectural concrete, plaster, wax, epoxy and polyester resins
✔ Casting of technical and prototypical components (bushings, dampers, vibration dampers)
✔ Seals, underlays and rubber-like components for changing operating conditions
✔ Copies of sculptures, figures, decorative and artistic elements with high attention to detail
✔ Molds for jewelry casting as well as small batch production of used parts
✔ Replicas and reconstructing elements with high tensile and tear propagation resistance
