Material Notes:

This room-temperature-curable polyether system is one of a family of polymer systems developed by Northstar Polymers for specific demanding work environments. Urethane elastomers molded with this system exhibit fine resolution of mold details, good performance in wet environments and good resistance to ultraviolet light. This combination of features makes elastomers molded from MPP-A30A perfect for applications including patterns designed to transfer an image to wet surfaces including concrete and many other custom applications.Information provided by Northstar Polymers.
