Rohm and Haas Offers New Dispersing Resins
Rohm and Haas recently introduced two high-efficiency dispersing resin products for organic pigments in aqueous media. These new styrene, acrylic-based polymers, Morcryl 410 and Morcryl 460 Plus dispersing resins, allow increased pigment loadings at higher pigment to binder rations without compromising color density and viscosity stability. Supplied in liquid form, Morcryl 410 and 460 Plus allow printers to control performance no matter what kind of process they run. The products enable broader compatibility with pigment types and other additives including conventional and neutral letdowns.

Union Process Launches New Production Mill
Union Process has produced a new production-sized small media mill for the ink, coatings and paint markets. The DMQ-10 combines the best features of a traditional horizontal small media mill with the added benefits of circulation grinding. The result is a versatile mill capable of providing a cost-effective, size reduction solution for grinding large quantities of material. Although the DMQ Series is able to operate in either circulation or continuous mode, using the mill for circulation grinding offers some unique benefits, including a narrower particle size distribution, the ability to continuously monitor the slurry and the ability to sample or add ingredients to the premix tank at any time.
