Plastisols As A Surface Coating

摘要

Vinyls are noted for their excellent physical properties including flexibility, toughness, unlimited color selection, and abrasion and chemical resistance. Vinyl plasti-sols combine these properties with the ease of liquid application.rnPlastisols are dispersions of fine particle size polyvinyl chloride (PVC) resins in plasticizing liquids. In addition to the resins and plasticizers, heat or light stabilizers, color pigments, flame retardants, blowing agents, or other additives may be included as determined by the intended end use. Plastisols may be fused in relatively thick sections without concern for solvent or water blistering; they are commonly referred to as 100% solids materials.rnOrganosols are closely related to plastisols. Simply stated, they are plastisols to which a volatile solvent or thinner has been added. Their utility arises from being able to use a liquid to apply a hard, tough film, in thickness generally limited to under 15 mils. Organosols maybe applied in many decorative finishes such as matted, textured, or hammer tone.
