Elvanol® 75-15 is suggested for evaluation wherever the high film strength and oil, grease and solvent resistance associated with higher viscosity, fully hydrolyzed polyvinyl alcohol are desired, but a lower solution viscosity and gel resistance are needed. The viscosity stability of Elvanol® 75-15 solutions makes it attractive for use in wet adhesives that require long term storage stability and which must withstand temperature variations, either in storage or during shipment. Gel resistance and excellent binding properties of Elvanol® 75-15 suggest its use as a secondary, or even a principle binder, in the manufacture of joint cements.

Regulatory & Compliance
- FDA Status
Elvanol® 75-15 polyvinyl alcohol complies with U.S. Food and Drug Administration (FDA) Regulations under the following Sections of Title 21 CFR, and may be used in contact with food, subject to the limitations and requirements therein:
- 175.105 - Adhesives
Technical Details & Test Data
- Resin Characteristics
Elvanol® 75-15 exhibit little tendency to increase in viscosity during storage. Solutions of Elvanol® 75-15 are much more resistant to temperature variation in that they develop essentially no gel structure if chilled lower than room temperature.
