Description
Thickener NL is a water based vinylpyrrolidone copolymer.
Application
THICKENER NL is a thickening agent for acrylic polymers, SBR and natural latex dispersions. It can be used as a stabilizing colloid for the incorporation of resin solutions into polymer dispersions.
Contrary to other thickening agents that are mostly effective in the alkaline range, Thickener NL develops the best thickening performance at pH values around 5.
