LK EM 400A & LK EM 400B
Silicone fluid emulsions
Product Overview
LK EM 400A & LK EM 400B are advanced silicone fluid emulsions that meet the requirements of industrial mold release and surface treatment applications. These emulsions consists high-purity silicone oils and stabilized with non-ionic surfactants, offering superior performance, ease of use, and broad compatibility with various substrates and production environments.
Developed for use in foundries, rubber, plastics, and textile industries, LK EM 400A & 400B serve as highly efficient release agents that prevent sticking, improve surface quality, and extend the life of molds and tooling. Beyond release applications, these emulsions also function effectively in the formulation of polishes and coatings particularly for artificial leather, wood, and fabric surfaces providing a smooth, glossy finish and long-lasting protection.

Typical Properties
Applications:
Mold Release Agent:
- Rubber & Plastics Molding: Acts as an efficient release agent for molding rubber parts, plastic components, and thermoset products.
- Footwear Manufacturing: Ensures smooth demolding of soles and heels in PU and rubber footwear production.
- Glove Production: Aids in the easy release of latex and surgical gloves from formers without tearing or sticking.
- Thermoset & Tire Molding: Performs effectively in hot or cold molding conditions for tires and thermoset materials.
Surface Polishing & Conditioning:
- Furniture Polishes: Used in formulations to enhance gloss and protection on wood and leather surfaces.
- Artificial Leather Finishing: Provides a smooth, glossy appearance and protective film on synthetic leather.
- Textile Finishing: Improves fabric softness, anti-static behavior, and process ability during textile finishing.
Specialty Applications:
- Fiberglass Release: Prevents sticking in FRP molding processes, ensuring clean, defect-free surfaces.
- Rubber Bands & Industrial Sheets: Prevents sticking of rubber products during manufacturing and storage.
- Cold Tire Retreading: Provides reliable mold release in cold cure tire retreading applications.
