Combined with bio-based polyol, FH-8279P is a modified polyester polyol. FH-8279P can be used in formulating urethane coatings, adhesive binders, sealants and elastomers. This product exhibits hydrolysis resistance, very good thermal stability and low polyol viscosity. It can promote adhesion to a variety of metal and plastic substrates. In flexible packaging adhesives, it can provide excellent adhesion under retort conditions and also provides a good hardness/flexibility balance and can promote pigment wetting.

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-8279P 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.
