Aldehyde Resin – Urea Aldehyde 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. Aldehyde Urea Resins used in combination with other resin binders like Urea Formaldehyde Resin, Melamine Formaldehyde Resin, etc. to improve its properties and production of all purpose pigment paste, and various other applications.
