I have made a paint based on Epoxy Phenolic Condensate , which is air drying. One of the paint batch has picked up viscosity and looks like gelling tendency. Please let me know remedy for salvaging this paint. Any additive, please let me know.

Try BYK- Chemie BYKANOL-N. This is an anti gelling agent and helps to maintain viscosity.

In addition to the previous answer, review your choise of the phenolic resin as they are classified according to their reactivity (the higher, the lower will the in can stability be). Also, use highly polar solvents. That improve solvability and hence the viscosity stability of the lacquer.

Hello,
In the mail you suggested to use highly polar solvents. Can it also be used for Acrylic Solvent Pressure Sensitive Adhesives? We have a tendency for our products to gel on short-term storage.
