Aldehdye Resin


POLYTONE UA SERIES: UREA ALEDEHYDE/DISPERSING RESIN

The traditional Aldehyde Resins produced from auto-condensed aldehydes are very rarely uses in coatings. The same is not true of Urea modified aldehyde resins. Which as well as being used as coating additive to improve gloss, body and UV resistance, are known as ideal “grinding resins” for pigment pastes because of their high pigment binding power and universal compatibility. Its used in combination with other resin binders to improve its properties and production of all purpose pigment paste.
