Properties & Uses
PN-355 is a high-quality copolymer with excellent application properties. It is widely used as a paint adhesive for both interior and exterior wall paints on various surfaces.
It forms a clear, crack-free film with good flexibility and is known for its water and scrub resistance as well as excellent stability against alkalis. Thinning is typically done with water. To reduce the M.F.F.T (Minimum Film Forming Temperature), the following agents can be used: butyl glycol acetate, butyl di glycol acetate, Texanol.
To improve freeze-thaw stability, ethylene glycol can be added gradually.
Storage
The emulsion should not be stored for more than six months before processing. Storage is preferable at room temperature, and it should never be exposed to direct sunlight.
