PPG-425 is a 425-molecular-weight polypropylene glycol. The terminal endgroups are predominantly secondary hydroxyls and have a relatively low reactivity. It is compatible with some polyether polyols and can be blended with other diols or triols to achieve desirable modifications of product properties. This polyol is acidified with a low level of phosphoric acid, making it suitable for use in isocyanate-terminated prepolymers.
PPG-425 polyol is used in the production of solid and microcellular urethane elastomers and adhesives. Typical applications include solvent and water-based coatings, high-modulus adhesives, cast elastomers, electrical potting compounds, thermal break, reaction injection moldings, inks, lubricants, antistatic agents, crude oil de-emulsifiers, and plasticizers. As with any product, the use of PPG-425 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.

Storage & Handling
- Storage Condition
PPG-425 polyol is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect product quality. This polyol can become quite viscous at low temperatures. For ease of handling, storage temperatures between 15°C (59°F) and 60°C (140°F) are recommended.
