Andur 75 DGP 2/Curene® 442

Andur 75 DGP-2 is a polyether (PTMG) based liquid isocyanate- terminated prepolymer. An elastomer with a hardness of 75 Shore D is obtained when this prepolymer is cured with Curene 442 [4,4'- methylene-bis (orthochloroaniline)]. Elastomers of lower hardness can be obtained by reaction with various polyols and their combination with Curene 442 and other diamines, and by the use of plasticizers. Andur 75 DGP-2 was designed to have a longer pot life for those who require more time for casting. Due to its lower %NCO, compared to other 75D materials, Andur 75 DGP-2 is much more economical to process, as approximately 20% less curing agent is required.
