Description

Description

This Thickener is a specialized additive designed to modify the viscosity of both tin-cure and platinum-cure silicone rubbers. When blended into standard liquid silicones, it transforms them into a pasty, thixotropic, or brushable consistency, making it ideal for creating silicone layers on vertical or complex surfaces without drips or sagging. By adjusting the amount added—typically just a few percent—you can precisely control workability, from lightly thickened to a dense paste suitable for hand-application or troweling. This makes it especially useful for brush-on moldmaking, patching, reinforcing seams, and coating models where pouring is impractical. The thickener maintains the silicone’s original cure strength, tear resistance, detail reproduction, and flexibility. It blends easily, disperses uniformly, and does not affect cure speed when used at recommended levels. Compatible with most tin and platinum systems, it offers reliable performance in professional moldmaking, special effects, prosthetics, encapsulation, and industrial applications. Whether you need controlled buildup, multi-layered brushable molds, or precise shaping, this thickener provides consistent results and enhanced application versatility.
