Technical Details & Test Data
- Metal Adhesion Performance in Coatings
Adhesion Performance1 Flexibility2 Cold-Rolled Steel 5 (excellent) Pass Galvanized Steel 5 Pass Aluminum 2024 5 Pass Aluminum 5052 5 Pass Zinc 5 Pass Tin 5 Pass Copper 5 Pass Brass 5 Pass Note:
- Coatings was formulated at 40% solids in toluene without external plasticizer. The adhesion test was carried out after the film was dried at room temperature for one week.
- 1Adhesion is rated on a 0 (poor, >65% coating area removed) to 5 (excellent, no failure) scale as described in ASTM D3359.
- 2Flexibility is determined by the degree of cracking at a bend. The bend was performed after drying the coatings for one and four weeks at ambient temperature.

- Preparing Solutions
Our resins dissolve at room temperature but require constant agitation to prevent solvent-swollen granules of polymer from forming agglomerates and sticking to the walls of the vessel. Important: The polymer beads should be sifted directly into the vortex of the stirred solvent to speed wetting-out and dispersion. Continuous low-shear agitation for periods of 1-12 hours, depending on the grade and concentration of resin, is recommended.
After the solution appears clear in the tank, a sample should be spread out on a Leneta card or glass. After the solvent evaporates and a film forms on the card or glass, there should not be any resin seeds. If there are any seeds, the tank should be agitated further to fully dissolve the resin. Tank agitation should not be stopped (except for sampling) until the film test indicates there are no resin seeds. Any cloudiness or residue may indicate that some polymer remains undissolved. The presence of water in the system can also cause cloudiness.
Solution time can be reduced by heating; most common solvents can be heated to approximately 49°C (120°F) without the need for reflux equipment. High-shear agitation also cuts dissolving time, but requires care to avoid overheating and excessive solvent loss.
