A hybrid material is made up of two separate components joined at a molecular level. Significant research has led to the development of hybrid polymers, which are ideal for use as sealants or adhesives. These materials combine the benefits of polyurethanes and silicones in a silane-curing organic polymer. These high-performing materials bring significant advantages, as detailed below, with easy handling and also conform to stringent environmental specifications.

Advantages

The low viscosity levels of these hybrid polymers mean no plasticizers or solvents are required in their production. This low viscosity also means the polymers can be processed easily, have a wide tolerance in formulation and have excellent mechanical properties.

Hybrid polymers can set extremely quickly without blistering due to the rapidity of the curing rate and will not require the use of a primer for most conventional materials. Alpha-silane technology is used as the mechanism for curing, which allows adhesives and sealants to be developed with no risk to health and therefore no need to be classified as a hazardous substance. They are highly elastic, as is typically found with silicones. The advantages these hybrid polymers have also include those similar to polyurethanes, such as being paintable and their impressive mechanical strength.

Hybrid polymers are considered an environmentally friendly option as they do not contain isocyanates or solvents. In addition, tin catalysts are not required during the curing process as it uses alpha-silane technology as the curing mechanism.

Uses

Technology is constantly evolving in the arena of hybrid polymers, so further uses are being developed all the time, as discussed by Northwestern University.

With the significant advantages outlined above, these hybrid polymers are ideal for do-it-yourself tasks in the home and for industrial use. They are perfect replacements for the bonding materials traditionally used on wood, parquet, mirrors and electric lighting networks. There are even hybrid polymers available now for use as metal bonding adhesives, such as those from http://www.ct1ltd.com/product-applications/metal-to-metal-adhesive/. A metal bonding adhesive can bond metal to metal but also attach metal to brickwork, wood and plastic.

Hybrid polymers should also be considered for more demanding uses, such as on boats or in sporting grounds. The construction industry is relying more and more on liquid waterproofing membranes, which hybrid polymers are contributing to significantly. It is an exciting and expanding industry.
