3.Uses and applicationsof the Heat-resisting chain extender：
DETDA with heat-resisting chain extender is a very effective polyurethane elastomer chain expansion agent, especially for the RIM (reaction injection molding) and SPUA (spray polyurea elastomer); also can be used as polyurethane elastomer and epoxy resin aromatic diamine curing agent, used for casting, coating, RIM and adhesive, but also is a polyurethane and polyurea elastomer chain extension agent
4.Packaging and transport：
Packaging for 1000KG/IBC barrels, 200kg drums or ISOTANK, the special packaging in accordance with the requirements of customers.
5.Storage：
Stacked in a cool/ dry/ ventilated place, keep away from heat/ fire, to prevent the direct sunlight, to avoid high temperature, do not sharp object collision damage.
