International. Hempel launched a new fire protection coating specifically designed to improve the productivity of passive fire protection (PFP) coating applications, by reducing the number of layers required and the process time required to apply them, saving time and costs.
Hempafire Optima 500 helps maintain the stability of steel structures in large infrastructure buildings such as airports, stadiums and shopping malls by providing protection of up to 180 minutes against cellulosic fires, optimizing for 120 minutes. It is a one-component water-based acrylic intumescent coating with zero volatile organic compounds (VOCs) and can be used for open or closed steel sections.
Hempafire Optima 500 is fast drying and highly resistant to sagging. The application, which can be delivered in two days as part of Hempel's PFP system, exceeds performance in hot conditions and provides two-hour fire protection in ISO 12944 C3 indoor environments.
It dries with an excellent aesthetic finish, which means that there is a minimum of surface repairs to achieve the required cosmetic finish when applying a top layer. The ease of application allows customers to improve their painting process by reducing the number of layers needed, minimizing drying times and maximizing application speed.
Together, these properties save time and money, as projects can be completed faster and with lower total application costs.
