Newport Adhesives & Composites

Description

NC-301-5 & NC-3015F are fast cure versions of Newport's NCT-301.  The modifications of the NCT-301 controlled flow, toughened epoxy resin, allow prepregs to be cured faster at lower temperatures when the process requires.  There is a significant sacrifice in shelf life versus NCT-301, but other processing and the physical properties are the same.

NC-301-5 (fast) and NC-301-5F (faster) are designed for applications in which a core or substrate will be involved that will not sustain temperatures as high as 250°F.  Examples are certain foams, vinyls, wood, etc. that will either outgas at higher temperatures or at longer exposure times, or will not sustain the necessary pressures of processing at temperatures as high as 250°F.  Where a longer cure time or a higher cure temperature is tolerable, NCT-301 is recommended for its superior out time (shelf life) and low exotherm.

NC-301 has an out time of several months at room temperature; NC-301-5 has an out time of about 3 weeks, and NC-301-5F has an out time of 7-10 days at room temperature.

Application

Properties

NC-301-5 and NC-301-5F can be supplied as the matrix on various substrates (e.g. woven glass, graphite, aramid or thermoplastic fabrics) or as a unidirectional fiber prepreg on graphite, glass or other fibers.  The mechanical properties of these prepregs are equal to those obtained with NCT-301.  Please refer to the Product Data Sheet on NCT-301 for those properties.
