Shin-Etsu KF-412 is engineered for multifunctional surface control in molding and processing environments. Its unique molecular structure enhances slip, spreadability, and anti-blocking performance, making it suitable for use in high-precision molding of plastics, rubbers, and resins. Unlike conventional dimethyl silicones, KF-412 offers improved compatibility with organic materials and coatings, enabling its use in paintable mold release applications. It also contributes to surface conditioning in automotive and industrial parts, where controlled lubricity and minimal transfer are critical.

Key features
Mold releasability: Silicone mold-release agents are non-compatible with almost all organic materials, so they offer outstanding mold-release performance.
Heat and cold resistance: They have excellent resistance to heat and cold and provide good mold-release results over a wide temperature range.
Rebound resiliency: Fabrics have excellent rebound resiliency due to the flexible elastic coating which forms on the fiber surface.
Chemical stability: They are chemically inactive, so they do not cause corrosion, swelling, or deformation of molds or molded items.
Can be used on complex molds: Silicone mold-release agents have low surface tension, so they provide good wetting of intricately shaped molds. This means that even complex molded items release easily from the mold
Plastic industry – Acts as a mold release agent and surface modifier in plastic molding processes, improving demolding efficiency and surface smoothness.
Rubber industry – Provides excellent release and thermal stability during rubber part manufacturing, reducing residue and enhancing mold life.
Resin industry – Used in thermoset and thermoplastic resin molding to ensure clean release and consistent surface quality.
Car industry – Supports molding and surface treatment of automotive rubber and plastic components, contributing to high-precision part production and reduced cycle time.
