Designed to prohibit liquids, solids and gases from entering through gaps and voids in metal seams, the new Loctite EA 3501 HT from Henkel (Rocky Hill, CT) is a one-part, heat-cure epoxy seam sealant that offers excellent adhesion to primed or bare, oily metals. This grey sealant maintains its flexibility, adhesion and color after exposure to paint bake processes up to 225ºC.
Compatible with many metal pre-treatment processes, as well as e-coat primer/paint and powder top-coat processes, Loctite EA 3501 HT can be easily pump-applied without preheating and smoothed in place with ease. This epoxy provides a tough, flexible bond on metal seams between welded or bonded joints, butt joints, and other visible seams to prevent rust and corrosion. Suitable substrate gauges range from thin sheet metals to rigid castings and extrusions.
