Keystone bolsters product portfolio

July 24, 2012

Keystone has introduced a green and blue addition to its line of surfactant-based zero VOC pigment dispersions—210-415-22 NeroTint Blue and 410-407-22 NeroTint Green—formulated for the waterborne wood and concrete industries. The NeroTint line has been engineered to provide excellent transparency, high gloss and uniform color in both spray and wiping applications, according to the company. These products are formulated with high-performance pigments, milled to very fine standards for ease of penetration, and are exceptionally clean and transparent, as well as very miscible in water or acetone containing systems. NeroTints have been QUV lab tested past 3,000 hours with good results the company said. Also on the new product front Keystone recently launched Keyplast Yellow F Solvent Yellow 104 chemistry for use in high heat engineering polymers. This dye will perform well in polyamides, polysulfones, PEEK and other difficult to process engineering polymers the company said.
