A química de tintas e revestimentos anti-incrustrantes para a indústria naval
Abstract
This Final Paper makes a brief review of the main A/F paints and coatings for ships
and vessels, the main protection material against marine biofouling that affects world trade as
a whole. Different types of A/F paints have been developed and improved over the years, the
first protection techniques originated from ancient peoples such as the Phoenicians, using
natural oils and resins mixed with antifouling agents. The complexity of the marine
environment and the processes that make up biofouling have led to these coatings being
improved. Modernly, the protection of vessels started to consist of systems based on synthetic
polymeric matrices, such as self-polishing paints with biocides derived from organotin
compounds that revolutionized the industry in this segment. However, the concern with the
environment brought new challenges to the market, when in 2003 the use of organotin agents,
the most used agent in the formulations of paints and A/F coatings, was banned, due to the
irreparable environmental damage caused by these compounds. Nowadays, the search for
new coating technologies that address different effective protection mechanisms and biocidal
agents that are less harmful to the environment are topics of research worldwide
