Silyl Modified Polymer (SMP) | Our Technologies

Technological performance is essential for stimulating change in our world. Processes also evolve to provide new solutions that improve productivity, performance, sustainability, and security.

Bostik SMP is a Silyl terminated polymers that are used to formulate one-component adhesive and sealants. It crosslinks in the presence of humidity. SMP adhesives were invented 40 years ago to bring together the best of polyurethane and silicone sealant technologies, and were first used in construction markets

Bostik’s range of Silyl Modified Polymer (SMP) can work for sealing, bonding, and glazing, and help you meet your needs in a variety of industrial applications in transportation and construction.

Frequently Asked Questions about Silyl Modified Polymer

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 affects the elastic bonding properties of the SMP technology, so we recommend 20 mm for ideal elastic bonding properties.
