Duncan...thank you...googling "fire retardant vinyl-ester resin" took
me immediately to:
Interplastic Corporation (interplastic.com), a specialty chemical
company with its headquarters in St. Paul, Minnesota.
CORVE8441M-AT is a promoted, fire retardant, vinyl ester resin. This
versatile resin contains antimony pentoxide to enhance fire
resistance. According to the ASTM E84 Tunnel Test, it has a Class 1
flame spread rating of less than 25 without further additives. This
product is corrosion resistant and is used in customer applications in
the corrosion, transportation, construction, and fire resistant
engineered products markets. Easily applied in spray-up, hand lay-up,
and filament winding operations.
This may be the ticket for me...but I'll check Dow Chemical too,
Fred
