49th Silicon Symposium, 101st Canadian Chemistry Conference (Dr. Farooq Ahmed), Edmonton, Alberta

Dr. Farooq Ahmed (Senior, Scientific Research Chemist) at CSL Silicones Inc. has been selected to present a paper titled “Elastomeric Polysiloxane Coatings”, at the Silicon Symposium that will be held May 29-31, 2018 in Edmonton, Alberta. This event will be held in conjunction with the 101st Canadian Chemistry Conference and Exhibition (CSC2018).  The 49th Symposium is very special, in that we are celebrating the chemistry of Bob West in the year that he turns 90 years young. It is truly hard to imagine that there is a silicon, or indeed main group, chemist working today who has not been influenced by Bob’s pioneering work efforts. The Symposium brings together approximately 150 scientists from around the globe, including world-leading academic and industrial researchers, postdoctoral fellows and research students.

For more information, please contact The Chemical Institute of Canada – Si Symposium.

Title: Elastomeric Polysiloxane Coatings

Author: Dr. Farooq Ahmed (Senior Scientific Researcher, CSL Silicones Inc.)

ABSTRACT

The purpose of a coating is to protect the substrate from damaging environmental effects by forming a barrier between a corrosive environment and the underlying material. To serve its purpose the coating itself must have resistances to degrading environmental factors such as UV radiation, heat, and corrosive ozone. Traditional/conventional coatings are loaded with anti-oxidant and UV stabilizing chemical additives that minimize the effects of damaging environmental factors to some extent. Elastomeric polysiloxane coatings are designed with polydiorganosiloxane polymers that contains a strong and flexible siloxane back bone, attached to organic moieties that make it hydrophobic. The combination of the inorganic back bone and the attached organic units creates unique property profiles in elastomeric polysiloxanes that make them a superior barrier against degrading environmental factors such as heat, UV radiation, oxidation by ozone and the damaging effects of moisture. The organic groups along the polymer backbone lower the surface energy of the crosslinked network, while making it highly hydrophobic. The exceptional resistivity of elastomeric polysiloxane coatings to degrading environmental factors prolong its service life significantly, without the need for any anti-oxidant and UV stabilizing additives, providing long-term protection to the coated structure. These properties make elastomeric polysiloxanes a superior coating for a myriad of applications, such as corrosion protection, anti-graffiti coatings, high voltage insulation, air and moisture barriers and protection from fire and heat. This paper will describe how the exceptional properties of elastomeric polysiloxanes allows them to serve as protective coatings and outperform other traditional/conventional coating systems in terms of functional application performance, life-cycle performance, and return on investment economics.
