Water Based Fire Protective Coating Thin Film Intumescent Paint For Steel

Introduction:

WFS‑101 Water‑based Thin‑Film Intumescent Fire‑Protective Coating for Steel Structure is an eco‑friendly fire‑protection material dedicated to steel structural members. Formulated with modified acrylic polymer and multi‑component intumescent fire retardant system, this coating is water‑dilutable without additional organic solvents. When exposed to flame and high temperature, it will expand and carbonize rapidly to build thermal‑insulating char layer to slow down temperature rise of steel substrate. It delivers robust substrate adhesion, supple cured film, outstanding alkali resistance and weather resistance. Suited for both indoor and outdoor steel fire‑protection works, it offers simple on‑site operation and long‑term reliable fire‑protective performance.

Product Characteristics:

· Compared with conventional decorative emulsion products, this fire‑protective coating exhibits remarkable film flexibility, tolerates minor deformation of steel components and maintains consistent construction performance.

· After full curing, it generates smooth, even coating surface with great leveling performance, effectively reducing brush marks and forming firm bonding force on pretreated steel surfaces.

· Scientific compound formula creates dense, high‑strength fire‑resistant barrier after construction, supporting multi‑layer overlay to achieve target fire‑resistance thickness.

· It possesses excellent water resistance, weathering performance and long‑term storage stability, adapting to various domestic steel‑structure fire‑protection engineering conditions.

Application:

It is designed for fire‑protective finishing on steel beams, steel columns, box steel and other metal building frameworks. Featuring easy‑to‑implement construction and stable film‑forming performance, it satisfies fire‑safety protection requirements for general civil buildings and on‑site industrial steel facilities.
