Kamicryl- 5360 is an acid containing Polyurethane crosslinked Acrylic emulsion copolymer, which when neutralised with a suitable base forms a highly viscous and very efficient thickening medium for a vast range of water based coatings.
Kamicryl-5360 being a polyacrylic thickner gives superior performance than conventional thickners like CMS, HEC. Storage stability of paint with
Kamicryl-5360 is much superior than with CMS or HEC.
If the system contains enough free alkalinity to neutralize Kamicryl-5360 then “Insitu” solubilization and thickening takes place. If no free alkalinity is present then alkali can be added to the system containing Kamicryl-5360 and “in-situ” thickening will occur. Kamicryl-5360 fully neutralizes at a pH approximately 8.0.
