Last month, global coatings company PPG launched its new epoxy intumescent fire protection coating for architectural steel, saying it offers up to three hours of cellulosic fire protection.
According to the release, PPG Steelguard 951 expands from a thin, lightweight film into a thick, foam-like layer that insulates the steel and maintains its structural integrity in a fire situation. This provides more time for people to escape, in addition to limiting damage to buildings and assets.
“Structural steel plays a critical role in modern architecture by enabling buildings to meet specific fire protection and corrosion resistance according to their function,” said Richard Mann, PPG global product manager, passive fire protection, Protective and Marine Coatings.
“PPG Steelguard 951 coating is unique in combining an aesthetically-pleasing finish with high corrosion protection and, most importantly, the ability to maintain the steel’s stability in the event of a fire.”
PPG Steelguard 951 reportedly can provide up to 3,500 microns dry film thickness in a single coat. It is also ready to handle the day after application due to its rapid curing properties while not requiring a top coat, reducing project time and costs.
PPG reports that the coating is based on its patented flexible epoxy technology, which offers excellent durability, edge retention properties and reduces the risk of cracks during handling and transportation.
The coating reportedly provides effective corrosion protection for very corrosive atmospheric environments up to ISO 12944 C5. Additionally, it is tested in accordance with all recognized national and international fire and corrosion standards, including EN 13381-8, BS 476, ISO 12944, GB 51249 and GB 14907 (for specified environments).
