OMNOVA Solutions introduces a patent-pending, formaldehyde-free insolubilizer that improves the coated surface of paper and paperboard, offering enhancements at every step of the printing process. OmnaRezTM4332 insolubilizer is a modified, blocked glyoxal-based resin that delivers exceptional cross-linking, resulting in reduced water sensitivity of the paper or board coating and pre-coat. It acts as an efficient fast-curing mechanism for insolubilizing hydroxyl-functionalized binders such as polyvinyl acetate, polyvinyl alcohol and starch.
OmnaRez 4332 insolubilizer offers advantages to coating formulators who require excellent high sheer rheology and viscosity and a broad pH range. This insolubilizer is compatible with a wide variety of common coating additives. When used in a size press or pre-coat application, OmnaRez 4332 insolubilizer creates a coating structure that increases holdout of additional coating layers and promotes adhesion between the coating and pre-coat layers.
OmnaRez 4332 insolubilizer improves ink/water balance (receptivity) in offset printing. Because of the cross-linking ability of this resin, printed paper and board exhibit increased half-tone dot definition, dot clarity, uniformity and visual snap, and press runs are more efficient due to cleaner blankets and fewer wash-ups.
OmnaRez 4332 insolubilizer is U.S. FDA compliant with 21 CFR 176.170 (approved for use as an insolubilizing agent in starch- and protein-based coatings that contact non-alcoholic foods, and limited to use at a level not to exceed 6% by weight of the starch or protein portion of the coating solids) and 21 CFR 176.180 (components of paper and paperboard in contact with dry food).
"This formaldehyde-free insolubilizer exemplifies OMNOVA's goal of providing the paper and printing industries with products that combine superior performance with reduced environmental impact," said Jim Vaughn, OMNOVA Solutions Market Manager, Paper Chemicals. "OmnaRez 4332 insolubilizer has been shown to be two-to-three times more efficient than other commercially available insolubilizers. This allows our customers to use lower amounts to achieve optimum performance, resulting in reduced formulation costs. Also, because OmnaRez 4332 works over a broad pH range, it can be used in formulations where other insolubilizers lose effectiveness."
