Resulting Properties
Plastisols require temperatures on the order of 130°C to 400°C to “cure”; however, they are commercially supplied as one component pastes without the need for metering or mixing prior to application. Moderately high bond strength can be achieved to many common substrates. Long-term flexibility is a distinct advantage. Plastisol adhesives used for laminating textile products generally have a low level of inorganic filler and a relatively high level of PVC resin. This adhesive formulation has a low and stable viscosity, and it is ideal for bonding PVC film to fabric.
