? ? APPLICATIONS XYLINK P-650 its chemical family is oligomeric aromatic diamine. This prodcut is liquid at ambient temperatures and can be mixed, cast and cured at room temperature. It can be used as a curative for various diisocyanates and their prepolymers and as an amine or anhydride cured epoxy modifier (to enhance flexibility). XYLINK P-650 applications include molding compounds, castable elastomers, tooling compounds and encapsulation compounds, as well as two-component adhesives, coatings, sealants and polyurea spray systems. Due to its ease of processing, XYLINK P-650 is excellent for field repair. When XYLINK P-650 is used to cure liquid MDI at room temperature, the resulting elastomers have a low shrinkage factor. ? ? Advantages # # Liquid at room temperature;
# Wide range of applications including polyurethane and epoxy systems;
# Excellent for field repair applications;
# Amber cure produces elastomers with low shrinkage;

? ? Safety and Handling Information Safety and handling information is contained in the XYLINK P-650 Material Safety Data Sheet, available upon request from XY Products. XYLINK P-650 is a brown liquid under ambient conditions. If it should become a solid due to exposure to lower temperatures while in transit or storage, gentle warming will return the product to a liquid state. ? Storage Information Keep containers tightly closed in a dry, cool and well-ventilated place. ? ? ? Suzhou Xiangyuan Special Fine Chemical Co., Ltd. Miss.
