| Résumé : |
Liquid ethylene propylene diene rubber (L-EPDM) has been known in the coatings industry for many years. These elastomers have found utility in ambient cure liquid-applied roof coatings. These resins, formulated into waterborne liquid coatings, may be cured with peroxides, metal driers, or UV radiation and can be used in ambient maintenance coatings for flat or low-slope roofs.
Simplified structure of L-EPDMRecently, formulations blending the L-EPDM with other common coatings resins have been developed. Elastomeric acrylics, alkyds and polyurethanes have been blended with the L-EPDM without the use of compatibilizers. Each of these systems has seen unique property improvements, such as surface wetting, adhesion, impact strength, and more.
Additionally, industrial heat-cure formulations have been developed for a broad range of temperatures. This paper will discuss L-EPDM waterborne suspension and blend properties, coating formulation, application and curing methods, and final film properties. |
