Description
Chem-Set 3620 Acrylic Sealing Tape is a 3620 sealing tape for difficult joint, overlap, and surface-sealing work where a conformable single-sided tape is easier to control than a wet sealant. The thick acrylic adhesive and tough ionomer backing help the tape bridge uneven areas, wrap over transitions, and maintain a tight seal across panels, joints, fastener heads, and repair edges.
3620 sealing tape Benefits
- Single-sided acrylic adhesive tape for sealing existing joints and overlaps.
- Ionomer backing is tough, flexible, abrasion resistant, and paintable.
- Translucent construction keeps repairs and inspection points easier to see.
- Conformable build helps the tape follow corners, rivet heads, screw heads, and panel changes.
- Primer can improve adhesion on low surface energy plastics and other hard-to-bond surfaces.
Use this tape when a shop needs a clean sealing path without tooling, mixing, or cure time. It works well for fabrication, transport body work, sign and display builds, weather-exposed equipment, and maintenance repairs where the tape must stay flexible after installation.
Common Applications for Joint Sealing
- Sealing panel joints, lap joints, and overlapping tape joints.
- Covering small penetrations around fasteners and brackets.
- Repairing joints on truck bodies, trailers, enclosures, and outdoor equipment.
- Masking and protecting edges that need a paintable, abrasion-resistant cover.
- Bonding to difficult surfaces after the correct primer and surface prep are confirmed.
Compatible Materials and Surface Prep
- Painted metal, coated panels, and composite skins.
- Many plastics and low surface energy materials when paired with a suitable primer.
- Dry, clean surfaces free of oil, dust, and loose coating.
- Firm roller pressure across the full tape width after placement.
