The high durability of the intumescent coatings for steel structures developed by CIN is certified according to ISO 12944-6:2017.
The Portuguese manufacturer of coatings CIN, specialised in corrosion and passive fire protection, has recently obtained a certification for its systems for corrosive environment C3. The high durability of the intumescent coatings for steel structures developed by CIN, which last over twenty-five years, is now certified under conditions specified in ISO 12944-6:2017 by an accredited external laboratory.
“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,” has stated Jorge Paiva, the product manager of CIN Performance Coatings.
There are several engineering and architectural works whose performances and aesthetics result from an exposed steel structure. In the case of fire, the unprotected steel structure of these buildings might reach in a few minutes the critical temperature that causes loss of stability and consequent collapse.
The newly certified passive fire protection coatings manufactured by CIN ensure the maximum resistance of metallic structures against high temperatures and corrosion:
- C-POX® PRIMER ZP230 FD is a polyamide epoxy primer pigmented with zinc phosphate that provides high-performance corrosion protection of metallic structures in industrial or building site applications. Applied in a single coat, it provides highly durable corrosion protection for corrosivity category C4 according to European standard ISO 12944.
- C-THERM® S100 is an intumescent acrylic coating for passive cellulosic fire protection of metal structures for interior and exterior use. Formulated to expand when exposed to high temperatures, it produces foam with very low thermal conductivity, which gives it excellent insulating properties for up to 120 minutes.
- C-THANE® S350 is a polyurethane enamel with excellent outdoor performance. It is recommended for corrosion protection of metal structures in aggressive environments and it is certified as a finish in painting systems certified according to parts 5 and 6 of the European standard ISO 12944. With excellent weathering resistance, proven in QUV-A accelerated ageing tests, it demonstrates perfect colour and gloss retention when exposed to cycles of UVA radiation and condensation, even after 6000 hours of testing.
