Is bonding the same as adhesion in wood finishes?

Coatings are tested and rated on adhesion not bonding. Bonding applies to adhesives. There is

1. Adhesion
2. "Wet Adhesion"
3. Cohesion

The difference between adhesion and cohesion, is that adhesion refers to the clinging of unlike molecules and cohesion refers to the clinging of like molecules. Adhesion is the mutual attraction between unlike molecules that causes them to cling to one another. Wet adhesion is sticking when moisture is in the environment.

All of General Finishes primers have excellent adhesion.

• GF White Undercoat has excellent adhesion to other coatings and wood substrates
• GF sanding Sealer has excellent adhesion to other coatings and wood substrates
• GF Stain Blocker has excellent adhesion to other coatings and wood substrates but takes longer to get full adhesion properties.
