Sagging is a common problem that occurs in the accurate application of coatings.
What visual appearance does sagging take?
Sagging appears as coating that runs before drying, leaving raised rivulets.
What probable causes are there for sagging?
- Low viscosity of the coating material

- Coating is applied too thickly
What suggested solutions can solve the problem?
- Avoid reducing coating or use a solvent with higher evaporation rate (check Product Data Sheet)
