Cas No.2991-84-6 is a polyamidoamine, polyether polyol series polyurethane curing agent. It is white solid powder when pure with little odour and no taste. As the polyether polyol component of polyurethane, it has excellent compatibility with polyester polyether polyol, polytetramethylene glycol polyether polyol and polyether polyol. It can increase frothy water resistance and reduce post foaming and improve surface flexibility of polyurethane.

This polyamidoamine, polyether polyol series polyurethane curing agent has excellent age resistance and good hydrolysis stability. In the properties, its water-soluble is good, and its shear strength stability is excellent, which makes it suitable for two-component systems with large proportion changes, while it also has excellent compatibility with many other polyurethane components.

Uses of this polyamidoamine, polyether polyol series polyurethane curing agent includes in the manufacture of high solid and low density flexible foam and elastomer, both of which have superior flexibility, tunability and aging resistance. These products have applications in automotive interiors and seating, as well as many other industries such as construction, military and sports. It is also great for making wheel-chairs, beds, mattress and some medical products.

This polyamidoamine, polyether polyol series polyurethane curing agent requires a strict ratio of usage according to its morphological properties and foaming properties. Generally, it should be used with leveling agent as foaming control agent. Its dosage should not exceed 5% of the total amount of polyol used. It can be added during low temperature process or can added last-minute before foam pouring.
