Description
Material Notes:
MPP-A80H has been specifically formulated to service applications where high elongation and good physical strength are required as well as where temperature during the process must be low for a very small shrinkage and a low processing temperature requirement. The component materials are liquid at room temperature allowing a user to process without heating the components. The reactivity is controlled specifically to be very slow so that the exothermic heat does not exceed the specific temperature range. This attributes to a very small shrinkage rate. This formula may be suitable when the high temperature at curing is an issue. The completely cured parts made of this material exhibit good tensile, elongation, abrasion resistance, and tear resistance properties. If the higher temperature for curing is not an issue, the higher catalyst level and elevated temperature will increase the curing rate to improve the turnaround rate.Information provided by Northstar Polymers.
