EPIBOND® 156-1 A/B

EPIBOND® 156-1 A/B epoxy paste is an off-white, two-component surface filler developed primarily for application over porous polymeric, wood, or metal surfaces. EPIBOND® 156-1 A/B epoxy paste has good adhesion, low shrinkage, and can be easily applied with a spatula, splining tools, or polyethylene squeegees. This surface filler is ideal as a “wipe-on” paste for filling imperfections on the surface of laminated composite structures such as radomes, edge joints, surfaces, or polystyrene foam.
