Biresin G27 LV is an unfilled fast cast polyurethane resin used for casting of master and core models, negatives and mouldings of small up to medium dimensions. Applicable for thinner and thicker layers. Also used for casting of art and crafts articles with excellent detail reproduction.
Casting of higher thicknesses (> 20mm) is possible with addition of 300 pbw fillers to 100 parts resin and 100 parts hardener, for thinner layers up to 200 parts.
Characteristics and Advantages
– Very good flowability
– Good wetting of fillers
– Short demoulding time, at mouldings with thin walls too
– High quality of surface detail reproduction
– Low shrinkage and good dimensional stability
– Very fine structure
Unfilled Fast Cast Resins
The unfilled fastcast resins are usually used for making detailed models and mouldings with thin walls due to their excellent flowability. They can, however, be cast in thicker layers by adding filling materials to them.
