PVC for paste application

® Vinnolit E 70 LF is a fine-particle, paste- making copolymer of vinyl chloride and 5 % vinyl acetate yielding low viscosity plastisols with an excellent storage stability (see diagram).

Due to its vinyl acetate content, Vinnolit E 70 LF can be easily processed at lower gelling temperatures.

Processing and Application:
Vinnolit E 70 LF may be converted into pastes by the standard methods, by dissolver or low- speed mixer. However, undue heating of the paste during mixing should be avoided since the vinyl acetate content may cause a rise in viscosity. Pastes based on Vinnolit E 70 LF can be applied by all the usual procedures. Vinnolit E 70 LF is a low temperature gelling, low-viscosity paste grade, recommended for coating heat-sensitive base fabrics, laminating pastes, carpet backings as well as automotive underbody and seam sealants. These applications also benefit from a high filler-loading capability as well as good adhesion to textile base fabrics and automotive metal surfaces. To lower paste viscosity and increase shelf life, Vinnolit E 70 LF may be blended with homopolymer extender resins such as Vinnolit EXT / Vinnolit C 65 V.

Remarkable properties are:

• significant lower gelling temperatures

• good adhesion at textiles and automotive metal sheets

• better mechanical properties

• better abrasion resistance in UBC-mastics

• excellent storage stability of plastisols
