What is BOSTIK MSR BEDDING COMPOUND and why choose it
BOSTIK MSR BEDDING COMPOUND is a one-component, permanently elastic adhesive/sealant based on silyl-modified polymer (SMP). It has been tested and certified according to the International Maritime Organization (IMO) fire exposure test procedures for surface flammability (Resolution A.653) and is approved for use on walls, ceilings and floors. Its combination of easy preparation, excellent adhesion and long open time makes it suitable for demanding marine bedding and bonding applications.

Applications and use cases
Typical substrates and bonding tasks
- Bonding steel, aluminium and polyester to wooden decks.
- Bonding steel, aluminium and polyester to teak boards or artificial decking boards.
- Bonding and sealing a waterproof plywood sub-deck to sub-decks made of steel, aluminium, polyester or wood.
- Use on walls, ceilings and floors where compliance with IMO surface flammability requirements is needed.
Adhesion characteristics
- Generally adheres well without primer to dry, clean and grease-free substrates such as aluminium, coated metal, wood and polyester (GRP).
- Under extreme environmental conditions (high thermal or mechanical loads and high humidity), the use of Simson Prep P is recommended on wooden substrates.
- Under these extreme conditions, Simson Prep M is recommended on closed (metal) surfaces.
Application method
- Can be easily extruded using a manual or air-powered sealant gun.
- The applied bead can be spread with a spatula.
- For sealing applications, the material should be tooled or smoothed within 25 minutes (at 20 °C / 50 % RH).
- For bonding applications, substrates must be assembled within 45 minutes (at 20 °C / 50 % RH).
- To make optimal use of the high deformability, a minimum adhesive layer thickness of 2 mm is recommended.
Cleaning
- Uncured residues and tools can be cleaned with a clean, lint-free cloth impregnated with Simson Liquid 1 or Simson Cleaner E.
- A preliminary test is recommended to check any possible harmful effects of these cleaners on the substrate.
Storage
- Store in original, unopened packaging.
- Keep in a dry place at temperatures between +5 °C and +30 °C.
- Storage stability: 18 months for cartridges, 12 months for tubes under the above conditions.
