Solving the cure speed modification dilemma
A new technology for the coatings, elastomers, sealants and adhesives market is now available from Huntsman Performance Products, one of the world's largest producers of amine products. Now the dilemma of modifying the cure speed of polyurea/polyurethane systems, slowing down primary amine reactions and hindering the competing reaction between water and hydroxyl groups, can be solved by using the new high content secondary aliphatic polyetheramines.
The XTJ-584, XTJ-585, XTJ-586 and the XTJ-576 aliphatic di- and tri-polyetheramines with little primary or tertiary amines, are the newest developments of the speciality amine products available from Huntsman Performance Products. They are liquid polyetheramines with each amine being secondary in nature. The secondary amine functional groups provide a much slower reaction compared to primary amines. They may be used in conjunction with, or to partially replace existing aromatic chain extenders to improve flexibility, colour, and leading to a reduction of the cost of the formulation.
