Common Questions:

  • How can I ensure the surface is adequately sprayed?

    By using a piece of cardboard a spray pattern may be tested. First make sure the spray equipment nozzle and air cap are clean and unrestricted. Hold the spray gun a distance from the cardboard that is a normal distance from the spray gun to the molding surface. Spray the mold release onto the cardboard in a sideways sweeping motion. The pattern should be solid yet dry quickly. Any splotches will show areas that may be under sprayed or unevenly applied. Liquid running down the surface means the liquid is being applied too heavily.

The Broadest Range of Mold Release Agents for Polyurethane Molding

Our mold release agents for polyurethane provide a competitive advantage to the largest and smallest manufacturers alike. We offer both water- and solvent-based release agent solutions that can maximize productivity while meeting the most demanding specifications and operating conditions. These release agents have been developed to provide:

  • Excellent part release
    We formulate our products to strike the perfect balance between release ease and part quality – no matter what your polyurethane molding application – so parts come out of the mold easily, without defects.
  • Optimal gloss level and surface finish quality
    We can customize our mold release agents to provide a variety of surface finishes, helping you meet your customer’sspecifications. For applications such as shoe soles, cast elastomers, spray PU skins or integral skin we can help you obtain any required gloss level -- from high gloss to shiny finish to matte. Do you need an open-cell surface? We can do that, too, in both solvent-based and water-based technologies. Do you need your surface to be dry? We can help with technologies developed to provide optimal release ease while eliminating that sticky, greasy or tacky feeling found with most conventional mold release agents.
  • Compatibility with secondary operations
    If you glue or paint your polyurethane parts after molding, Chem-Trend has products that are compatible with these secondary operations. In some cases, by switching to our products we can help you eliminate a post-molding cleaning or preparation step before this secondary operation, allowing you to reduce your operating costs and improve your operating efficiency.
  • Lower scrap rates
    By using our release agents we can help you improve release ease and part surface finish, both of which will lead to lower scrap rates.
  • Cleaner molds
    Because we balance our products’ slip and barrier properties, our mold release agents are designed to produce as little build-up in the mold as possible.
  • Less downtime
    A properly designed release agent, correctly applied, results in less build-up, easier to remove residues, and ultimately less down time because you won’t need to clean your mold as often.
  • Higher quality parts
    We customize our products to your specific requirements. Lower build-up on tooling and less sticky, greasy residues makes for higher quality parts and more satisfied customers.
  • Water-based, no/low VOC emissions, cleaner safer working environments
    If you’re in a region that has strict VOC regulations and air quality permitting, or if you need products that are safer and non-flammable, Chem-Trend has developed a portfolio of products that are water-based, low VOC or even VOC-free. Not only do these products provide you with a solution to lowering your VOC output, they also provide optimal performance just like the solvent-based products you’re used to. To find out more about these topics, read our case studies on VOC reduction and how we helped a leading steering wheel manufacturer.
  • Tin-free formulations where required
    If your customers require your processing chemicals to be tin free, we are able to supply tin-free release agents for almost all applications. In fact, we have tin-free formulations that have the same performance as tin containing formulations. At Chem-Trend, we’re used to working with lists of “forbidden” chemical substances so you don’t have to.
