Polyurethane Mold Release Agents | ReleaSys™

Mold release agent for polyurethane castings

High Performance, Specialized Polyurethane Mold Release Agents

Miller-Stephenson offers the most advanced polyurethane molding release agents solutions, back by over 40 years of research, development and  expertise.  Our mold release agents are relied upon by global industries to ensure efficient, cost effective, and high quality release of their molded parts.  Large and small manufacturers can expect higher productivity and profitability through reduced downtime, increased acceptance rates and improved part quality.  We offer both water and solvent formulations that offer increased worker safety, cleaner molds, cost efficient, and ease of use.

Benefits of Polyurethane Mold Release Agents:

  • Superior part release
  • Minimal or Zero Transfer
  • Lower defect rates
  • Higher quality parts
  • Less downtime / Higher efficiency
  • Water-based, no/low VOC emissions, cleaner safer working environments
  • Optimized surface finish

Utilization of Miller-Stephenson exclusive crosslinking polymer chemistry, our ReleaSys™ and ShieldSys™ coatings delivery unparalleled properties that polyurethane molders look for: Superior release ease, cleaner molds, reduced build up, reliable surface quality, and high cost effectiveness.  Customers which switch to our high performance coating systems typically see reductions in mold release thanks to our highly efficient, thin film coatings that deliver improve release while utilizing less material.  Of particular importance is our focus on reduction of build up associated with polyurethane operations.  ReleaSys polyurethane release agent systems are designed to tackle this issue by delivering improved release performance in thinner release agent coatings. Thinner, durable release coatings reduces build-up and greatly extends up time. The results? – high quality parts, more parts made per shift, and less downtime – a potent combination.
