|
APPLICATIONS |
||
| Hydroxybutyl Acrylate gives hydroxyl functional groups to an acrylic polymer backbone. The hydroxyl groups act as crosslinking sites for hydrophilicity, improving adhesion and resistance against corrosion, fogging and abrasion. End applications include adhesives, coatings, sealants and thermosetting paints. | ||
