      toluene max. 7
  Gelation (200 3)C, hrs max. 2
  of nonaqueous extract 6 - 7

Applications:

  • used as a 5% solution in benzine for treatment of metal dies to improve parting at extrusion of articles of polymeric materials.
  • an effective release coating:
    • for tier-sheets in production of sheet glass-reinforced phenol plastic,
    • for dies in manufacture of parts of polysterene, foam plastic, plastic material,
    • in moulding of glass fiber plastic sheets and plates,
    • in manufacture of coiled light-reflecting film,
    • in production of release paper.
Shelf life - 6 months


  3. RELEASE AGENT KP-222


mixture of silicones and waxes in petroleum solvent C 2-80/120 or benzene reforming raffinate.
