摘要

Traditional rust preventive formulations utilize waxes and oils to leave a thin,temporary barrier film on a metal surface.The delicate and tacky nature of these chemistries may not be fit for every application and end users often seek alternatives that are more durable.Acrylic polymer films have been sought as a suitable replacement,providing a dry-to-touch alternative that offers ease of handling with acceptable corrosion protection.These types of coatings are already used in direct-to-metal protection applications and in many cases provide semi-permanent corrosion protection.This study will evaluate acrylic polymer formulations that are commercially available as one-coat rust preventives,instead of the expensive,multi-coat systems often used by end users.This study will directly compare the performance of the coatings in standard corrosion tests and compare the physical properties of the protective fluids themselves.
