Plastisol Compounds

The jig or Hanger to be coated is preheated before immersion into the room temperature plastisol. The inherent heat gelling characteristic of a plastisol causes the coating to gel on the hot jig or hanger. The thickness of the coating is dependent upon the mass of Jig or Hanger the preheat temperature and the time the hot Jig or Hanger is allowed to remain in the dip tank. Plastisol viscosity is not a major controlling factor with regards to film thickness. A subsequent fusion step may be required. The necessity of a subsequent fusion step will be determined by the thickness of the coating and the temperature of the plastisol furthest from the substrate will determine this. Often, subsequent fusion of the coating will be required to obtain the maximum physical performance for the coating.
