Our series of infusion and pultrusion resins are ideal for infusing even 40 foot or longer bridge pilings or pultruding FRP rebar. These resins are customized for each application.
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).
This line of vinyl ester resins are lower intrinsic viscosity versions of the CORVE8300 series, corrosion resistant vinyl ester resins for use in centrifugal casting, pultrusion, vacuum infusion, and RTM applications, and are well suited for use in fabricating tanks, pipe and process equipment, as well as other applications. When cured, they exhibit physical properties similar to the CORVE8300 line. CORVE8100-50 is our workhorse product. It is a nonpromoted, low viscosity, corrosion resistant vinyl ester resin for use in vacuum infusion and RTM applications. CORVE8100-50 is manufactured from ingredients listed as acceptable in the FDA Code of Federal Regulation Title 21, CFR 177.2420. This resin may be safely used as a component of articles intended for single or repeated use in contact with food as prescribed in the regulation.
