Fillers and effects powders are often added to casting resins to change the properties of the plastic, lower the weight or achieve a variety of finishes including metal, stone, porcelain, marble, wood, etc.
URE-FIL™ Fillers
URE-FIL fillers disperse easily in Smooth-On materials. They can be added to materials in different proportions to achieve a variety of working properties and effects. Some fillers are designed for cost-savings, others are designed for specific casting effects or improved physical properties. Other URE-FIL fillers are designed specifically for thickening materials for brush-on or trowelable application.
URE-FIL 3
Added to polyurethane resins and castable epoxies to reduce cost. Recommended starting mix ratio is 1A to 1B to 1 part URE-FIL™ 3.
Improve castable plastic dimensional stability or create marble effects. Maximum ratio before compromising the physical properties is 1A:1B to 2 parts filler.
Fibre-based filler that can be added to Smooth-On polyurethane and silicone rubbers, polyurethane plastics and epoxies to thicken for brush-on applications.
Metal powders for creating cold-cast metal effects. Mix with polyurethane or epoxy resins to achieve the appearance and weight of solid metal castings. Available in bronze, brass, copper, aluminium, and nickel-silver (pewter effect). Apply as slush coat then backfill for authentic metal finish that can be polished.
