UR 3490 is a polyurethane surface casting resin designed for foundry tools (patterns, core boxes) on aluminium pre-forms, concrete resin etc.
Characteristics and Advantages
– Higher shore hardness D 67
– Good abrasion and impact resistance
– Good heat resistance (Tg ~100°C)
– Low toxicity
– Quick hardening
– Low moisture sensitivity
Flexible Polyurethane Elastomers
Elastomeric Casting Resins are high quality PUR systems with a wide range of shore hardness levels (Shore A 40 to D 67) used in manifold application areas.
The tough elastic systems are mainly used for high abrasion resistant liners (face casting process) for core boxes and match plates with long working life.
