Product Description
LOCTITE EA 3501HT is a one-component heat-cure epoxy seam sealant designed for primed, bare or oily metal surfaces processed through high-temperature paint-bake operations. The gray high-viscosity paste requires no component mixing and has typical vertical and horizontal sag of 0 mm under SAE J2433, Method B. The recommended 30-minute cycle uses a minimum cure temperature of 160 deg C, a typical temperature of 175 deg C and a maximum of 225 deg C. After cure, the sealant remains flexible and is used on welded or bonded seams, overlap joints, butt joints and visible seams in automotive and industrial metal assemblies.
Key features
- No-Mix Heat Cure: One-component epoxy paste uses a 30-minute paint-bake cure cycle, with a typical cure temperature of 175 deg C, a minimum of 160 deg C and a maximum of 225 deg C.
- Non-Sag Paste: Typical vertical and horizontal sag are both 0 mm under SAE J2433, Method B.
- Paint-bake seam sealing: Designed for primed, bare or oily metal seams processed through high-temperature paint-bake operations.
Applications
Sealing automotive and industrial metal seams, overlap joints and butt joints where heat cure through a paint-bake process is used.
