DeCAL 4201 is an acrylic binder ideally suited for use in waterbased flexographic inks for paper and corrugated board. The product exists as an alkali soluble carboxylated copolymer emulsion but can also be supplied in its neutralized varnish form as DeCAL 4202. In both cases inks prepared using either DeCAL 4201 or DeCAL 4202 possess excellent machine stability/resolubility, viscosity/pH stability, favourable viscosity/dilution curves and excellent pigment wetting characteristics. 1. Typical Properties: Tg : 35C Acid value : 77mgKOH/g solid resin Initial softening

point : 100C See Technical Data Sheet for more details 2. Applications: Neutralisation of DeCAL 4201 can be achieved using any suitable alkali or volatile amine. These include Ammonia, Monoethanolamine(MEA), Diethanolamine (DMAE), Aminomethyl propanol(AMP) or Triethanolamine(TEA). DeCAL 4202 is supplied pre-neutralised with the commonly used Monoethanolamine(MEA). DeCAL 4201 tends to swell considerably in the early stages of neutralisation. As a result it is recommended that the product be prediluted to with water prior to any neutralisation and then left to stabilise for several hours afterwards before use. For full solublisation of the polymer the pH must remain above pH 7 where it exhibits excellent pH/viscosity stability.
