KM-742T is a water-based silicone mold release agent designed for industrial applications. Its low-concentration formula provides excellent release performance while maintaining a smooth surface finish. Ideal for use in rubber, plastic, and other molding processes, KM-742-T ensures easy mold release, reduced residue, and improved production efficiency.

• Widely Applicable - KM-742T is primarily composed of dimethyl silicone oil, with a specific gravity of approximately 1.00 and a pH close to 7, exhibiting an excellent neutral state and suitable for application on a wide range of surfaces. It exhibits stable mold release performance on a variety of substrates, including rubber, plastic, and metal.

  
  

• Excellent Mold Release - KM-742T's non-polar molecular structure effectively reduces interfacial bonding between the mold and the part, enabling quick and clean mold release. Its emulsion evenly spreads on complex molds, forming a dense and stable release film.

  
  

• Heat Resistance - KM-742T maintains stable performance in both high and low temperature environments. Excellent mold release performance is achieved within a temperature range of -20°C to 180°C, ensuring mold release without poor release or surface damage during alternating hot and cold conditions.

  
  

• Chemically Stable - This product is chemically inert and well tolerates acid and alkaline systems. Performance retention exceeds 90% when used within a pH range of 3-10. This means it will not cause corrosion, expansion, or deformation to molds or molded parts.

  
  

• Suitable for Complex Molds - KM-742T's low surface tension allows it to spread evenly and improve wettability in molds with complex shapes and fine structures. When used in molds with fine patterns, the mold release rate for parts exceeds 98%, effectively preventing molding defects caused by complex mold structures. This makes it highly practical in the production of precision molds and complex parts.

• Rubber and Plastic Molding - During the rubber and plastic molding process, KM-742T reduces adhesion between the part and the mold, ensuring a quick and smooth demolding process. In high-volume injection molding, its use has increased production efficiency by over 20%. It also doubles the mold cleaning cycle, reduces maintenance downtime, and ensures stable, large-scale, continuous production.

  
  

• Surface Treatment - In industrial surface treatment and finishing processes, KM-742T acts as a mold release agent, significantly improving part surface finish and preventing scratches and residue. In metal die-casting or plastic hot press molding, it reduces surface roughness to below 0.8, meeting higher aesthetic and functional requirements and enhancing the added value of the finished product.

  
  

• Hot Press Lubrication - During hot press molding and compression processes, KM-742T provides stable lubrication, reducing the friction coefficient between the mold and the part. Experimental results show that the friction coefficient can be reduced by approximately 30%, extending mold life and maintaining stable demolding performance even under high temperature and high pressure conditions. It is particularly suitable for molding heat-resistant engineering plastics.

  
  

• Automotive Maintenance - In the automotive industry, the KM-742T is used for molding plastic parts such as interior trim and weatherstrips. Its low-residue properties ensure that component surfaces remain free of oil stains and marks, reducing the need for secondary cleaning. In practice, part qualification rates have increased to over 98%, contributing to improved assembly efficiency and surface aesthetics.
