Henkel launches Loctite EA 3501 HT, a one-part, heat-cure epoxy seam sealant that offers excellent adhesion to primed or bare, oily metals. The sealant is designed to prohibit liquids, solids and gases from entering through gaps and voids in metal seams.
Tough and Flexible Epoxy Sealant
Loctite EA 3501 HT maintains flexibility, adhesion and color after exposure to paint bake processes up to 225ºC. The sealant is ideal for use on a range of outdoor power and heavy equipment vehicles, including agricultural, construction, utility, marine, sports/leisure, work trucks and trailers.
The sealant is compatible with many metal pre-treatment processes, 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. The epoxy provides 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.
Loctite EA 3501 HT is a grey paste in both its uncured and cured states and is composed of 100 percent solids. The epoxy cures on exposure to 160ºC heat for approximately 30 minutes. Loctite EA 3501 HT does not sag horizontally or vertically at elevated temperatures and offers Shore A hardness of 65 to 85. On both mild and oily steel, the sealant achieves cohesive failure in peel or shear force modes.
