Question 1

Can IPA 99% be used as a co-solvent in waterborne coatings?

Accepted Answer

Yes. IPA is widely used at 2–10% loading in waterborne acrylic and PU dispersions to improve substrate wetting, flow, and film coalescence. It is completely miscible with water and evaporates cleanly without residue, making it compatible with most waterborne formulations.

Question 2

What makes IPA suitable for surface preparation before coating?

Accepted Answer

IPA effectively removes fingerprints, oils, waxes, and mold-release residues from metal, glass, and plastic substrates. Its fast evaporation (rate ≈2.3 vs BuAc=1) leaves no residue, ensuring good adhesion of subsequent coatings. It is also less aggressive than acetone on sensitive plastics.
