CIN fire protection products for steel structures are uniquely certified to last for more than 25 years

22 December 2022

CIN’s intumescent system makes buildings safer through a unique certificate on the market that distinguishes the durability of products over a quarter of a century.

A pioneer in the market for corrosion and passive protection against fire, CIN, a Portuguese company and Iberian leader in the coatings market, presents a certified system for corrosive environment C3 with very high durability, over 25 years, that coincide for corrosive categories C5 with medium durability and C4 with high durability. The tests were approved by an accredited external laboratory, which certified that the performance of the C-THERM® S100 intumescent remains unchanged even after ageing tests under conditions specified in ISO 12944-6:2017.

There are several engineering and architectural works whose beauty and aesthetics result from an exposed steel structure of modern and bold design: airports, sports stadiums, large shopping centres, schools and skyscrapers, places which, due to their public and recreational utility, concentrate many people inside. But if a fire, breaks out, the potential for disaster in these high-occupancy buildings is worrying and frightening. In these situations, an unprotected steel structure can reach, in a few minutes, the critical temperature that causes loss of stability and consequent collapse.

Jorge Paiva, Product Manager for CIN Performance Coatings, states that "the brand works daily for innovation in the sector and, to do this, it is fundamental that we understand the difficulties and needs of the market. CIN detected the need to certify the durability and safety of its intumescent system, combining both corrosion protection and passive fire protection for metal structures, based on the main standards in force, two fundamental axes to ensure their stability."

With numerous advantages for use in the construction sector, adequate steel protection is a known necessity, both because of it trends to corrosion and the fact that it loses stability when subjected to high temperatures.

CIN has more than 20 years of experience with passive fire protection, and the brand’s products have increased in the durability of these same metal structures.
