Résumé : |
Two 'renewable' monomers were evaluated as replacements for standard monomers in a self-crosslinking core-shell acrylic dispersion resin. The substituted materials polymerised without problems. Properties of clear and white industrial wood finishes were compared with those of a reference acrylic dispersion. |
Note de contenu : |
- The evolution of greener binders
- Green variations on a waterborne acrylic dispersion
- How the substitutions affected MFFT and hardness
- Evaluation of formulated coating properties
- Chemical resistance is slightly reduced overall
- Good results achieved, further optimisation desirable
