Our architectural/Theme Park resins provide the best balance between flame retardancy, smoke generation and processibility to meet the needs of all applications.
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).
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. CORVE8440 and CORVE8441 are specified for use by Universal Studios
These are nonpromoted, fire retardant vinyl ester resins for use in the manufacture of fiberglass parts with excellent dimensional stability that meets the transportation applications fire and smoke requirements. They require the addition of Alumina Trihydrate (ATH). Fiberglass reinforced panels with 60-70% reinforcement by weight will have an ASTM E162 flame spread rating of less than 25 and ASTM E662 smoke density of less than 200 after 4 minutes in the flaming mode. CORVE8430 is a spray up resin while CORVE8434 is formulated for infusion applications.
CORVE8421 is a brominated, thixotropic corrosion resistant 100% vinyl ester resin that is Class 1 flame only.
CORVE8425 is a brominated, thixotropic corrosion resistant 100% vinyl ester resin that is Class 1 flame and smoke "out of the drum." It requires no additives and is MACT and SCAQMD 1162 compliant.
MVR8051 is a pre promoted, thixtropic halogen-free modified vinyl ester resin designed to be used with ATH. It does not contain MMA. Laminates fabricated with MVR8051have achieved E84 Class A status (flame spread index of 25 or less and smoke development less than 450 per the NFPA 255 Standard. MVR8051 passes UL V-0, ASTM D635, E162, and E662 plus SMP-800C, Docket 90 and MVS302. MVR8051 is perfect for making architectural and theme park components and is specified by Disney for use in laminates 1/4 inch thick.
