LOCTITE MR5412
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Solvent-Based Neoprene Contact Adhesive
- Fast Air-Dry Tack
- Repositionable During Initial Assembly
Product Description
LOCTITE® MR 5412 is a solvent-based neoprene rubber contact adhesive designed for maintenance, repair, and general-purpose bonding applications. The adhesive develops fast, high-strength bonds and provides waterproof performance on both porous and non-porous substrates. It is particularly suitable for bonding weatherstripping, insulation, rubber components, and trim materials to wood and metal surfaces, while allowing repositioning during assembly before final bond formation.
