Mix 1:1 with Thick Hardener; also runs 2:1 Slow or 4:1 Fast for cure-speed controlWorks with None - NOT for wetting out fiberglass, carbon, or Kevlar; use Thin Epoxy Resin for laminating
Resin TypeEpoxy - thick bonding & coating resin (no-sag), resin only
Mix Ratio1:1 with Thick Hardener; also runs 2:1 Slow or 4:1 Fast for cure-speed control
ViscosityVery thick - high build, no sag on vertical surfaces
Pot Life30-35 min @ 80°F with the 1:1 hardener
UV ResistanceNot UV-stable - topcoat for sun exposure
Works With (Fabrics)None - NOT for wetting out fiberglass, carbon, or Kevlar; use Thin Epoxy Resin for laminating
Works With (Fillers)All BS fillers - Cabosil, milled fibers, microballoons for fillets & putty work
Apply OverWood, fiberglass, metals, masonry - scuff-sand & solvent-wipe first
Best ForBonding, fillets & high-build coats - buy ala carte to match your hardener stock
