                       General information: The product is sensitiveto 

                       moisture. Storage at higher temperatures will result

                       in increase of color and viscosity. Storage at 

                       significant lower temperatures will result in 

                       solidification. This solidification is reversible
                       by briefly heating the product withoutadversely 

                       affecting the quality of the product.
