Description

Silanes have long been employed in many formulations including coatings, adhesive and sealant formulations. If their most well-known role is as adhesion promoters, they can also be used as crosslinkers to improve thermal-, solvent- and environment- resistances, to improve mechanical properties and give them the right visco-elastic behavior once the formulation is cured. Since many silanes react readily with water, it is also possible to take advantage of this latter property to use silanes as moisture scavengers. To obtain the expected properties, it is important to thoroughly understand silane chemistry and to know the parameters that govern reactivity in the pot as well as after the application of the formulation.

As an illustration of the multi-functionality of silanes, we will study what is known as hybrid technology. It is labeled as such because it consists of attaching a non-organic functionality (the silane) to an organic backbone. This technology generally uses several silanes for three different roles: Crosslinker, adhesion promoter and moisture scavenger. We will see different strategies to make it possible to synthesize silane-terminated polymers, and to incorporate them into a formulation that shows improved adhesion and UV resistance compared to fully organic equivalents. The details of a typical hybrid-based formulation will be studied, and the role of each ingredient will be described.

Technology expert

Patrice Lehmann has been immersed in silane chemistry since 1990 when he began to use them in various applications: hot melt adhesives, water-based formulations, foundry resins, glass fiber, engine coolants, pipes, wire and cable. Then he specialized his developments in the use of silanes for adhesives and sealants; this is when he developed the polymers called SPUR, standing for silylated PolyURethanes. To understand the advantages of this technology, he also developed different formulations to reach a broad range of mechanical properties and studied all the ingredients that can be used in such recipes and the impact of them. Since 2010, he is busy as technical service consultant to explain users how to get the most of this technology.
