Development / Applications
EM 3090 is a medium molecular weight PVC emulsion resin with a fine particle size. Its viscosity starts relatively high; however, under low shear stress, its viscosity gradually decreases. Under high shear stress, it exhibits pseudo-plastic flow. Both conditions assume a medium plasticizer dosage level (70-100 phr).The plastisol produced from this resin exhibits good foaming properties and a long shelf life. It also offers good thermal stability when combined with a wide range of thermal stabilizers, and a fast gelation rate with a semi-gloss surface finish.This emulsion resin produces plastisols ideal for extended coating of foams, particularly high-build-expansion foams with a very fine, closed-cell structure. It also produces high-performance, high-viscosity, compact coating plastisols without the need for thickening agents. For foaming applications, it is recommended for use with K/Zn or Na/Zn activators.EM 3090 can be applied in plastisol rotary screen printing, plastisol transfer spreading, or plastisol spraying processes. It can also be used as an automotive sealant applied by spraying.
