Polycraft RTV Silicone Thixotropic Thickening Agent (Thixo), Mould Making, Casting, Resin Art, Professional Grade Thickener for Silicone, Easy Mixing and Application, Non Toxic Formula 25g

Enhances Viscosity - Add up to 25g per 1 kilo of Silicone, thickening the liquid silicone to create moulds with greater detail and precision. Brush-Up Technique Friendly - Ideal for users preferring a brush-up technique for mold making, preventing silicone from running off the model and seeking the lowest point. Smooth Application - Thixotropic Agent thickens silicone for smoother application onto the original, ensuring a bubble-free mould with correct usage. Optimal Mould Quality - For best results, apply a first coat of un-thickened Silicone to create a bubble-free mould, achieving professional-grade results. Temperature Considerations - Thixo may firm up in low temperatures, simply place the container in a hot water bath to restore it to a liquid form. Not suitable for use with high-temperature or food-safe silicone mould-making rubbers.
