Intumescent coatings

intumescent coating is a special coating≠σ used on the surface of flammable su>₽βbstrates, which can r→←©educe the flammability of the surface♣≥ of the coated material and ret☆™≈ard the rapid spread of fire. It ™✘→​is used to increase the fi§'♥♥re resistance of the coated mater↕∏ial.

intumescent coatings are based o×φ∑≤n their flame-retardant mechanism:int☆≥↕umescent coatings ca¶↑✘n be divided into two types, intu'↕∞±mescent intumescen₩£∞t coatings or non-intumescent in¶★tumescent coatings.

    Non-intumescent↓♦↕↔ coatings are mainly c​ oatings that are flame-resistant ↓↔→★or non-combustible, and ca>$n release fire-extinguishing gas•÷λ'es under flames or high temp♣ eratures to prevent or delay t→₽©αhe coating from catching fire. ♥↔

The intumescent intumescent coating is that its coating under±βγγgoes intumescent carbonization u>™nder flame or high temperature,>↓  forming a non-flammable ★​ sponge-like carbon ★® ∑layer that is tens or even hundreds ofα✔" times thicker than the original÷✘β£ film, in order to isolate÷$♣≠ the external flame from heating δ"the substrate. At the±← same time, a large amount of non-∏₽∞φcombustible gas is generat¶σ ed during the coating film'''''"♣'''''''''''''''''''''''''''s melt expaδ≠φnsion process, which dilu±♣"tes the combustible gas g'≠enerated by the thermal decomp'​‍$osition of the substrate, which can e>€ffectively prevent the spread of the Ω≥flame, thereby achieving the role₹$ of protecting the substrate.

    ≠‌φ← Our products can be wide¥→ly used in intumescent intumescent coatings. When the intumescent intumescent coating is heated, it acts a♠•$s a strong dehydration carbon-forming'β≤₽ catalyst, which dehydrates the ₽&ε✘carbon-forming agent into carbon ↔&↑>while generating a large amount↔♣ of non-existent gas t∞α>o expand the coating. It φ✘α✘is an indispensable pΩ♥™art of intumescent coatings.
