Formaldehyde-free insolubilizer improves the coated surface of paper and paperboard

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. OmnaRez™ 4332 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. “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,” said Jim Vaughn, Omnova solutions market manager, paper chemicals.
