What glue is used to bond sunroof rubber seals?
2 Answers
HY-T160 glue can be used to firmly bond sunroof rubber seals. Here is an extended introduction to it: Introduction to HY-T160: HY-T160-PP/PE slow-drying glue is mainly used for bonding various difficult-to-bond plastic products, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ABS, nylon, sponge, film, foam plastic, etc. It also has good adhesion to organic glass, rubber, metal, bamboo and wood, fabric, and paper. It is particularly unique for cross-bonding between plastic and metal or non-metallic materials. It is an ideal bonding material for industries such as home appliances, radio, decoration, handicrafts and toys, insulation materials, packaging and printing, etc.
I've repaired many car sunroof issues. For sunroof seals, you must use automotive-specific adhesive sealant—never regular household super glue like 502 or strong adhesives. While regular glue bonds quickly, it dries too rigid and lacks elasticity. Over time, this causes the seal to crack and can even corrode the rubber surface, worsening leaks. I recommend using 3M-brand polyurethane sealant—it's waterproof, heat-resistant, and accommodates the seal's thermal expansion/contraction. When applying, thoroughly clean both the seal and frame to remove old adhesive residue, apply a thin layer of sealant, press firmly, and let cure for 24 hours. If the seal is severely aged, replacing it entirely is better than repeated repairs. Regular sunroof seal inspections prevent leaks, avoid moldy interiors, and maintain cabin dryness.
