What are the benefits of Silyl Modified Polymers (SMP) adhesives and sealants?

Boost your productivity and quality while reducing your cost-in-use

  • Increase productivity with reduced number of preparation steps.
  • Robust process to limit risk of incorrect surface preparation and need for rework and customer claims.
  • Reduce cost-in-use by eliminating the need to buy chemicals, facilitate stock management, free-up production floor space, and reduced needs for consumable.

Protect your employees, customers and the environment

  • 100% isocyanate & solvent Free No need for REACH isocyanate training / No pictogram
  • Less waste thanks to a more robust process, and less used product packaging
  • Reduced needs for VOC solvent based products
  • Easy to clean off on hands and tools
  • Long shelf life of 12 to 18 month 

Performances for more robustness and flexibility!

  • Easy to gun at low temperature
  • Improved ageing performance
  • Excellent adhesion to a wide variety of substrates
  • Stable mechanical characteristics across a wide range of temperature
  • Cured material remain flexible at low temperatures

What are the innovations for Silyl Modified Polymers adhesives and sealants?

Bostik has a long history of expertise in Silyl Modified Polymers (SMP), and has become a reference and a leader in this technology. Bostik is also working on the development of technology through innovations that enable SMP to be used in a wider range of applications. Our innovations include:

Frequently Asked Questions about SMP Adhesives and Sealants


Is SMP technology compatible with plastics such as PMMA, PC, ABS?


Our SMP technology is compatible with plastics such as PMMA, PC, ABS. It has been tested and approved globally and is popular among plastic producers.


What is the bondline dimension (general and project related) for SMP technology?


The bondline dimension could work with a minimum of 2 mm thickness. This thickness impact the elastic bonding properties of the SMP technology, so we recommend 20 mm for ideal elastic bonding properties.
