What others say about MPK Silicones and Resins.

  • Both myself and my staff were very pleased with the quality and performance of QM 2125. I found the QM 2125 to perform virtually identically with other quality molding silicones but with better pricing
    Steve Wang Biomorphs
  • MPK's resins and silicones are of the highest quality...every batch is consistent and always performs with the reliability...MPK-70-180 is the best modeler friendly resin I have ever used.
    James Hakola – MrDandy.com
  • The paint adhesion was far superior to any silicone I’ve used before. So much so that even after extensive handling, there was no detectable wear...I thoroughly endorse the mold making silicones that Mike Knott has provided me.
    Paul R Barnes - FX MASTERS
  • MPK 2125 performed beautifully, capturing excellent detail and our molds cured at standard hardness in only 2 hours (nothing I had ever seen before). Now it is the only silicone that enters my facilities for mold purposes.
