Liquid Silicone Rubber for Mold Making (Soft)

This soft Liquid Silicone Rubber (LSR) is designed for making flexible, high-detail molds for epoxy resin, soap, candles, plaster of Paris, gypsum, polymer clay, and craft projects. With a simple 1:1 mixing ratio and Shore A 15 hardness, it offers excellent flexibility, easy demolding, and accurate reproduction of fine details.

The thin to medium viscosity flows easily around intricate shapes and textures, making it suitable for mold making, prototyping, sculptures, figurines, architectural details, and casting applications. Its low shrinkage helps maintain dimensional accuracy, while the fast-curing platinum-cure formula allows molds to be ready in approximately 3–5 hours at room temperature.

Once cured, the silicone remains soft, durable, and elastic, making it ideal for repeated casting and easy removal of finished pieces.

Key Features:

• 1:1 mixing ratio by weight (Part A : Part B)
