| Elvanol 90-50 is suggested for evaluation wherever the high film strength and oil, grease, and solvent resistance associated with higher viscosity, fully hydrolyzed polyvinyl alcohols are desired, but a lower solution viscosity is needed. For example, it should be useful in such applications as paper coating and sizing, adhesives for porous substrates including paper and paperboard, hot-water-soluble film, and as a binder for pigments or other solid particles. Elvanol 90-50 is particularly useful as a pigment binder for ceiling tile primers. |
