PVC Plastisol Knife Coating for Technical Fabrics
topic
PVC plastisol knife coating applies 100 percent solid PVC resin dispersed in plasticiser at coating weights of 100 to 600 grams per square metre in single or multiple passes, fused in infrared or hot air ovens at 170 to 200 degrees Celsius that cause the PVC resin particles to dissolve in the plasticiser and form a continuous polymer film, producing the durable PVC-coated fabrics used for truck tarpaulins, awnings, inflatable structures, and protective clothing.
Role
Produces PVC-coated fabric for industrial and outdoor applications through the 100 percent solid plastisol system that eliminates solvent and water evaporation from the drying process, enabling high coating weight application in single passes and reducing drying energy compared to solvent and water-based systems, with plastisol fusion conditions governing the completeness of PVC gelation that determines coating flexibility, tensile strength, and low-temperature performance.
