I. Water immersion /weather resistant intumescent fire protection coating, for combustible electrical & communication cables
Cable fire suppression coatings are thus a critical step in achieving fire safety and ideally they should provide the following three key protections:
FIRE RESISTANCE : Protection of cables against direct fire exposure /fire survivability – circuit integrity : (Governing international test standard – IEC 60331-11)
FLAME RETARDANCE : Prevention of fire propagation on cables : (Governing international test standard – IEC 60332-3-21, IEEE 383 & FM 3971)
SMOKE PREVENTION : Preventing toxic smoke generation /Outgassing : (Governing international test standard – NES-713 & NCD-1409)
In addition, the above two protections, should be tested & certified, for a minimum period of >30 minutes, ideally at a fire temperature of >1100°C (Hydrocarbon).
The longer this protection time span, naturally the more superior the coating /protection capability.
The cable coating should also be water immersion /weathering resistant.
Firex EC 43 is a heavy-bodied, water-based intumescent coating which is designed to prevent flame spread along the jacketing of electrical (or other) cables and to provide a thermal barrier for protection against heat damage caused be external fires /internal short circuiting .
Firex EC 43, today, uniquely provides the longest time span fire protection, in the world, in both these two criteria’s, at direct fire exposure >1100°C (Most cable coatings provide either only one of these protections, or only for a minimum time interval of 2-5 minutes and that too only against low intensity ISO /Cellulosic fires /750°C ).
Worlds first cable fire suppression coating to pass IEC 60331-11, Fire survivability
– Circuit integrity under hydrocarbon fire direct exposure (1130°C)
–Cable fire : 60 MINUTES protection /Fire survivability – Circuit integrity with re-energisation. (Also passes 50 minutes /2mm DFT# ) : FIRE RESISTANCE

240 Micron DFT, three part (Epoxy Primer + Epoxy Intermediate + PU Top Coat) or two part (Epoxy Mastic + PU Top Coat), systems are today generally used in critical industrial maintenance applications, for corrosion prevention- fluid /gas handling pipelines, storage tanks, surfaces exposed to acidic fumes, coastal areas, high corrosive areas…
Today these systems do not perform adequately, i.e., corrosion & metal loss are extensively seen in industrial applications, generally due to the following reasons:
SOLUTION : Modern technology “True surface tolerant” – Ultra low surface tension, epoxy – Zinc & MIO coating systems, designed to provide warrantied barrier corrosion prevention, on ST2 /ST3, manually prepared surfaces, despite the presence of surface contaminants such as, rust, moisture, oily substances as well as absence of a blasting generated anchoring profile.
Unique “Low Surface Tension” ensures superior surface wetting & adhesion. Zinc-MIO provide enhanced barrier protection.
(A) CHEMCOINT RL 500 PF : Unique Wet-Tolerant, Rust-Tolerant Epoxy Primer /Finish Providing Both Cathodic Sacrificial as well as Barrier Protection without needing a Top Coat – 3 in 1 System.
(B) 1040 STANGARD (ST) “TRUE” SURFACE TOLERANT EPOXY + 725 PUTC : 3 Years warrantied corrosion prevention on ST2 /ST3, manually prepared, rusty /moist surfaces.
“True surface tolerance” – excellent penetration & adhesion, even on rusty, wet, contaminated surfaces. With combination of MIO, provides an impermeable barrier. Excellent resistance to both mild acids & alkalies. Protects metal – long term. Superior durability…far better than epoxy mastic systems.
