AQUEOUS COMPOSITION FOR VULCANIZATION OF FLUORO RUBBER AND ARTICLE COATED WITH FLUORO RUBBER

摘要

A one-fluid type aqueous curing composition of a fluoroelastomer comprising water, a fluoroelastomer at least a part of terminal groups of which are non-functional groups, and a curing agent. This composition has a long pot-life and provides a cured film with a high strength while it contains the fluoroelastomer at a high solid content. An article coated with a coating layer formed from this aqueous curing composition, in particular, the rolls of office automation equipment, can solve the drawbacks of articles coated with a film formed from a conventional one-liquid type aqueous curing composition of a fluoroelastomer, for example, insufficient strength of the coating layer.
