Sika provides a large range of filled and unfilled fastcast resins especially suitable for making master models, core models, quick negatives and patterns.
Filled fastcast resins are especially suitable for making e.g. master, core models, negatives and patterns with large dimensions and are characterized by low shrinkage.
The unfilled fastcast resins are usually used for making detailed models and moldings with thin walls due to their excellent flowability. They can, however, be casted in thicker layers by adding filling materials to them.
