Polycup® 1884 Crosslinking Resin is a water-soluble,
polyamide-epichlorohydrin crosslinking
agent for carboxylated SBR latices, CMC, polyvinyl
alcohol, and other water-soluble polymers. It also
reacts with starch to impart water resistance. In
latex-based adhesives, the addition of as little as
0.5% Polycup solids, based on latex solids, will
increase green bond strength of the adhesive and
improve its modulus, tensile strength, and
dimensional stability.
Water-based formulation
Contains no formaldehyde
Cures under neutral pH conditions
Easy-to-handle liquid
Use With Sodium Carboxymethylcellulose
(CMC): Polycup resins can be used with CMC to
develop water-insoluble films and coatings with good
flexibility and strength. The addition of 5 to 10%
Polycup solids to a CMC composition will make it
essentially insoluble. However, the composition will
remain somewhat water-sensitive, and it will swell to
a slight degree in the presence of water.
Use With Polyvinyl Alcohol (PVA): PVA alone
does not produce a water-resistant coating.
However, a high degree of water resistance can be
imparted to PVA coatings and films by adding 5 to
10% Polycup resin solids to PVA solids.
Use With Starch: Starch-based coatings and
adhesives can be made water-resistant by adding
Polycup resin to the starch either prior to cooking or
afterwards, in amounts ranging from 2 to 20% resin
solids, based on starch solids.
Water-soluble, formaldehyde-free, polyamide-epichlorohydrin. Used as a crosslinking agent for starch-based coatings, in combination with PVA to produce a water-resistant coating, and in combination with CMC to develop water-insoluble films and coatings with good flexibility and strength. Provides water resistance. Cures under neutral pH conditions.
