How to solve the poor adhesion of water-based paint after soaking in water?

Problems: water-based acrylic resin, self-drying system,60 ℃ / 120 minutes after the bubble row down into the water, can use fingernail.But after taking out to wait

for water to be able again, how should solve?

Response:

This test method is still very harsh.General water - based resins, acrylic acid, polyurethane or Self-crosslinking single component system, are difficult to

meet.Consider the following alternatives：

1.Avoid resin systems with common surfactants.

2.If the resin system contains carboxyl group, why consider adding zinc salt to increase the crosslinking degree?

3. You can also consider adding some wax emulsion to increase the hydrophobicity of the formula.
