These guides and tables shown on the linked pages demonstrate the diversity of applications of the Gabriel family of products and the expected performance features & benefits that may be realized with their use in coatings, adhesives, plastics, and composites. Additionally, the many possible chemistries in which the Gabriel line can be incorporated is suggested.
HOW TO USE TABLES
The tables that follow (use index above) are arranged in two fashions: product selections (in bold yellow) for best recommendation) are listed for performance attribute versus application technology, followed by product selections for numerous chemical approaches versus application technology. The Phenoxy line of products find many uses as modifiers to other chemistries as well as utility as the sole resinous vehicles in coatings, adhesives, etc. Compatibility with urethanes and epoxy resins is excellent. In many cases modification with Phenoxy resin and its many derivatives is sufficient to upgrade the properties of the formulation. In those cases where crosslinking can occur with hydroxyl functionality the Phenoxy resins will further enhance properties like hardness, abrasion resistance, and chemical resistance.
SOLVENTS and DILUENTS
Phenoxy resins favor polar, aprotic type solvents in solvent borne applications although incorporation into formulations having hydrocarbon or aromatic solvents is quite possible if sufficient polar solvents can also be used. The preparation of most solvent borne solutions of Phenoxy resin is usually straightforward given adequate agitation. For faster results some heating is required commensurate with the solvent choice.
Waterborne Phenoxy resins are colloidal dispersions dependent on pH maintenance above 6.5. Generally they are compatible with colloidal dispersions of other polymers stabilized in the same manner such as polyurethanes, polyesters, acrylics, and epoxy esters. With waterborne epoxies poor shelf stability is observed due to gelling tendencies of the contained epoxy species because of the slightly basic nature of the Phenoxy dispersions.
