Starch binder composition for fiber mats |
(57) A starch binder composition for fiber mats is disclosed which comprises a starch,
a starch crosslinking agent, an anti-wicking agent and preferably a polymer strength
additive. When the starch binder composition is applied to a fiber mat, e.g. a polyester
fiber mat, the treated mat exhibits less stretching, shrinkage and wicking than is
common with conventional latex binder systems. The starch binder composition can also
be used on glass mats as a partial or total replacement for conventional urea-formaldehyde
resin binders with the treated mat exhibiting improved dry, wet and hot wet tensile
strength when compared to a urea formaldehyde resin binder containing a conventional
acrylic latex.
