3. 1R32 A2 673S High Adhesion Acrylic
Acrylic coatings have
Excellent electrical properties
Easy application
Easy repairs
Humiseal introduce 1R32 A-2 673S featuring:
Adhesion promoters for low surface energy boards
High clean solvent mixture for no-clean boards
Variants suitable for dip and selective coating
Available immediately

4. 1R32 A2 673S High Adhesion Acrylic
Low surface energy can be caused by flux residues, or solder resist
Surface energy can change after wave solder or reflow
This board surface energy 34 – adhesion could be low

5. 1R32 A2 673S High Adhesion Acrylic
1R32A R32A2 673S
High adhesion acrylic performs better
on low surface energy boards

6. 1R32 A2 673S High Adhesion Acrylic
AB Chimie AVR80 Humiseal 1R32A-2 673S Performs well compared to typical competitor material
