Product Description
Andur 2-920AP is a polyester/polyether TDI terminated coprepolymer suitable for the preparation of urethane elastomers. When cured with Curene 442 [4,4'-methylene-bis (orthochloroaniline)], an elastomer with 92 Shore A hardness will be produced. Elastomers of lower hardness can be obtained using blends of Curene 442 and polyols and other diamine curatives, or by the use of plasticizers.
