Combined with bio-based polyol, FH-856P is a diethylene glycol-phthalic anhydride-based polyester polyol. This product can be used in formulating urethane coatings, adhesive binders, sealants, and elastomers. FH-856P exhibits hydrolysis resistance, very good thermal stability, and primary hydroxyl advantage. It may promote adhesion to a variety of metal and plastic substrates. In reactive hot melt adhesives, it provides short open time and good green strength.

Safety considerations
Most FH series polyols generally present no significant hazard in use when simple precautions are followed. However, some FH series polyols are hazardous and before working with these systems it is necessary to understand the hazards involved in handling all of the components and to establish and follow safe work procedures. Material Safety Data Sheets, product literature and safe handling and storage information are available for the polyurethane components supplied by Hug Chem. Recommendations for handling, storage and disposal of any ingredient not furnished by Hug Chem should be acquired from the supplier.
Storage and Packaging
FH-856P 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 processing. This product 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.
The shelf life is twelve months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
