The new Crystic Fireguard 75PA Excel intumescent fire protection topcoat is a product upgrade of the long established Crystic Fireguard 75PA, reformulated by Scott Bader’s R&D team to offer better FR properties and handling.
An intumescent topcoat provides a passive fire protective barrier to block the path of a fire. When fire attacks the intumescent topcoat it causes a chemical reaction which makes the topcoat expand to form a protective layer that insulates the surface over which it has been applied. While it will not protect indefinitely from an unchecked fire, Crystic Fireguard 75PA Excel can withstand a direct flame at a temperature of 700 deg. C for over 60 minutes without the laminate behind catching fire. This is a significant period of time to contain a fire and prevent it from rapidly spreading, which can help to avoid catastrophic fire damage and save lives.
The original Crystic 75PA has been specified for over 30 years in critical internal applications which need to meet BS 476 Part 6 Class 0 or BS 476 Part 7 Class 1 FR test standards. It has been used for interior parts in buildings, rail and other public transport vehicles, as well as in the marine sector where it is used to protect the engine compartments of both working boats and pleasure craft, such as Princess Yachts International luxury motor yachts.
Julian Spooner, Composites Project Manager for Princess Yachts International commented: “Safety is taken seriously at Princess Yachts and all our vessels have to follow the strictest guidelines. Where fire protection is required we use Scott Bader’s Crystic Fireguard 75PA Excel. It is easy to apply and gives a first class finish. More importantly it gives a very high fire performance that means the laminates will achieve a Class1/0 performance to BS 476 Parts 6 and 7. We take pride in not just the finished look of our yachts, but insist on the very best materials and workmanship for all the manufactured parts.”
Laminators using the new version on the shop floor of Wright Composites in Northern Ireland said that Crystic Fireguard 75PA Excel had an improved consistency and cure, with much better handleability. The product is still cured with a standard MEKP catalyst.
