ADFAST Corp. (St-Laurent, QC) is one of the leading supplier of adhesives, caulking, fasteners and sealants inCanada - indeed about 70% of all sealants in building windows in Canada are derived from ADFAST'sproducts. These materials find application in construction, packaging, transportation, marine sealants, to namebut a few; indeed, in any industry requiring sealing, fastening and adhesion. Consequently, the market is highlycompetitive and innovative products constantly need to be developed to match the ever-increasing,sophisticated needs of consumers. ADFAST has been developing their own products to increase theircompetitive advantage and desire to be more responsive to their customer's needs by being able to preciselytailor their formulations. The proposed collaboration thus will combine the expertise in development ofpolyurethane hybrid sealants already present at ADFAST, along with their well-equipped characterizationfacilities with the added value provided by the Maric labs in design, synthesis and characterization of polymers.This proposal is two-fold: 1) provide a bench-mark to quantify ADFAST's existing formulation in terms ofmolecular weight, composition and physical properties and 2) use the bench-marks established to evaluatelatitude in starting materials with particular emphasis towards making greener formulations via the use ofbio-based monomers for the polyurethanes.
