CoREZYN brand corrosion and fire retardant resins offer a broad range of product types to meet every need.
These fire retardant vinyl esters are brominated, bisphenol-A epichlorohydrin epoxy-based resins, and therefore also exhibit outstanding corrosion resistance. Our vinyl ester and modified vinyl esters resins meet the stringent testing requirements of the ASTM E84 Tunnel Test, with flame spread ratings of either <75 (Class 2) or <25 (Class 1), as well as an ASTM E162 flammability rating of 20.5, and an ASTM E662 smoke emission rating after 90 seconds of ≤1, and after 240 seconds of ≤20. We have a selection of these resins that can be formulated to meet UL 94V, ASTM D635, MIL-R-21607E or MIL-R-24719. The product line includes products for filament winding, hand lay-up, spray and vacuum infusion. These resins are well suited for use in conventional corrosion applications, such as tanks, pipe and process equipment, as well as transportation components and building and construction. Both promoted and unpromoted versions of most of these resins are available. The flagship products in this category are CORVE8400 (unpromoted) and CORVE8401 (promoted).
