FLAMMADUR® A 77 HF
FLAMMADUR® A 77 HF Fire Stop Cable Coating consists of:
- A 77 HF Intumescent fire protection coating
- V 906 Protective Varnish
Range of application
When exposed to fire, FLAMMADUR® A 77 HF expands and cures to an insulating carbon foam, protecting underlying materials against heat. FLAMMADUR® A 77 HF is designed to prevent the outbreak of fire caused by cable burns. With FLAMMADUR ® A 77 HF short-circuits or sparks, even off high voltage cables, cannot spark fires. In case of an external fire, damage to cables and insulation is delayed for a minimum 30 minutes. As a result, escape routes and power supplies stay available for longer. Cable fire load is significantly reduced.
Smoke generated from the protected materials is < 400%/min. The coating does not affect the cables‘ current carrying capacity in any way.
