Applications and use cases
Recommended uses
- Bonding polychloroprene- and hypalon-based coated materials, particularly for inflatable boats.
- Bonding various rubbers (including SBR).
- Bonding polychloroprene-rubber to metal substrates.
Surface preparation
General preparation
- Surfaces must be clean, dry and free from dust or grease.
Inflatable boats (polychloroprene / hypalon)
- Sand the surface using fine-grit abrasive.
- Remove dust and clean with Bostik Neoprene solvent or methyl ethyl ketone.
- Carry out this cleaning step no more than 1 hour before bonding.
Rubber / metal bonding
- Sand and/or degrease surfaces as appropriate.
- The exact preparation method depends on the substrate type and origin and must be optimised, as it strongly influences final performance.
Bonding procedure
- Mix Transprene 113 M1 Base with 8% by weight of Desmodur RFE hardener. Ensure thorough mixing until completely homogeneous.
- Apply the adhesive manually with a brush to both surfaces (double application).
- Apply the first coat and allow to dry for approximately 10 minutes.
- Apply the second coat and allow to dry for approximately 15 minutes.
- Check both surfaces and carefully bring them together, ensuring precise alignment.
Cleaning
- Fresh adhesive and tools can be cleaned with Bostik Solvant Neoprene.
