Dow Introduces New High Solids Hollow Plastic Pigment For Coated Paper and Paperboard Applications

12-Dec-2002

The Emulsion polymers business of The Dow Chemical Company has introduced a new high solids hollow plastic pigment with Binder, HSB 3042NA, for a broad range of coated paper and paperboard applications. The new high solids plus binder product could enable faster operating rates and improved sheet gloss and opacity. HSB 3042NA is produced at 42 percent solids level, which is six percent higher solids than a simple blend of hollow and latex binder. Overall, formulators can expect about two percent higher solids levels at typical plastic pigment levels in formulations.

"In order to achieve this great improvement in solids, Dow combined its proprietary hollow technology with its leading styrene butadiene (S/B) latex technology and state-of-the-art manufacturing process technology to develop HSB 3042NA," says Donna Babcock, North American Paper Latex Marketing Manager, Dow Emulsion Polymers. "This hollow and latex combination is not just a physical blend of pigment and binder. Our unique manufacturing process allows us to provide customers with a hollow plastic pigment product that includes binder, which delivers higher solids - higher than any other supplier in the industry."

The S/B-type binder is included in the product to assist in obtaining the higher solids levels, according to Sandra Jones, Technical Service Representative, Dow Emulsion Polymers. The hollow plastic pigment contributes to a smoother and glossier coated sheet. Plus, the pigment is ammonia-free, which is particularly desirable where low odor levels are necessary.
