CHILION Technology announced today that the AFCP series adds a new D-model — Flourguard FLOURGUARD® Liquid Shield, a microcapsule fire-suppressant coating, with the 1KG pail launched first. Targeted at electrical-fire hazard points such as distribution cabinets, busbar enclosures, and cable interlayers, it covers the irregular and narrow gaps that AFCP patches cannot fully reach; the 5KG engineering size will follow later.
The AFCP F/A/P/D/M patches excel at covering flat surfaces and short curved faces, but industrial busbar enclosures, rear-wall bolt groups in cabinets, and bottoms of switch inserts are small and oddly shaped, with high cutting waste for patches. Liquid Shield exists as a coating — a brush reaches any curved surface, completing the roughly 20% of irregular areas patches miss, forming a "patch + liquid" complementary system with patches; overall fire-protection cost drops about 15%–25% versus patches alone.
Liquid Shield uses the same clean agent as AFCP patches, Novec 1230 (ODP=0, GWP=1, no secondary damage to precision circuits), encapsulated in the coating via microcapsule structure. Each micron-scale capsule seals leak-free at room temperature; above 140°C the shell ruptures and the agent releases instantly — equivalent to brushing countless miniature AFCP units onto the cabinet wall. It breaks on fire, suppresses on break, with no power, detector, or cylinder linkage required.
The currently launched 1KG size shares the same agent and trigger mechanism as the later 5KG. Applied mainly by brush, in two layers of about 0.5mm each, with a dry-film total thickness of about 1mm; the substrate must be de-rusted and de-oiled (wipe with isopropanol or acetone), applied at 5–35°C, relative humidity ≤85%. Coverage reference: 1KG two coats about 1.5–2.5㎡; after the 5KG size launches, about 8–12㎡.
The coating naturally solidifies over time; storage hinges on "sealing" and "shade". After each use, tighten the lid and expel as much air as possible; store in a cool, dry, dark place, away from heat and direct sunlight. Well sealed, it keeps long-term; if left open or exposed to high heat and sun, the surface skins and dries like paint and is ruined. Use up soon after opening; keep the lid tight between applications.
Liquid Shield fits distribution boxes, elevator shafts, socket boxes, distribution cabinets, busbar enclosures, cable interlayers, and storage battery compartments. It can be ordered together with EAPD devices and AFCP patches, or purchased per pail for local retrofit trials. Sealed original pails keep 12 months; the 1KG size is in regular supply.
