Revestimientos intumescentes

Ayudando a que el acero permanezca frio

Un sistema intumescente es una combinación de diversos componentes que en caso de incendio reaccionan entre sí como resultado del aumento de temperatura para formar una espuma de carbono. Esa espuma alcanza un espesor de 10 a 100 veces el revestimiento aplicado originalmente y aísla el material de sustrato mediante su baja conductividad térmica. Esto puede ser esencial en particular para estructuras de acero, ya que éstas podrían perder su estabilidad estructural durante los incendios, cuando las temperaturas superan los 500 °C. Ejemplos de este tipo de edificios son aeropuertos, centros comerciales, hospitales y complejos de oficinas.

Como proveedor principal del ingrediente clave, polifosfato amónico, Clariant tiene una amplia experiencia sobre las materias primas usadas para fabricar revestimientos intumescentes y en el desarrollo de fórmulas para revestimientos intumescentes, ya sea en base de agua o solvente.

Los productos Exolit® AP que se usan son polvos finos y blancos basados en polifosfato de amonio.

Servicio para nuestros clientes

Durante más de 30 años Clariant ha sido un proveedor líder de retardantes a la llama base fósforo. Estamos en condiciones de apoyar a nuestros clientes en el desarrollo de fórmulas adecuadas de revestimientos intumescentes.

En nuestro laboratorio de Knapsack, Alemania, podemos comparar el rendimiento de un rango de diferentes fórmulas utilizando pruebas de incendio estándar. De esta manera, podemos apoyar a nuestros clientes en el desarrollo de nuevas fórmulas para cumplir nuevas normas o retos sobre requisitos de seguridad contra incendios.

  • Productos Exolit® AP

    • Exolit® AP 420

      Exolit AP 420 is an approx. 45 % clear to cloudy aqueous solution of a short-chain ammonium polyphosphate. más

    • Exolit® AP 422

      Exolit AP 422 is a fine-particle ammonium polyphosphate (phase II) produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colourless, non-hygroscopic and non-flammable. más

    • Exolit® AP 423

      Exolit AP 423 is a fine-particle ammonium polyphosphate produced by a special method. The crystal modification is phase II. The product is largely insoluble in water and completely insoluble in organic solvents. It is a white powder, non-hygroscopic and non-flammable. más

    • Exolit® AP 428

      Exolit AP 428 is a fine-particle ammonium polyphosphate produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colourless, non-hygroscopic and non-flammable. Exolit AP 428 differs from most other commercial products in the following ways: - greatly reduced solubility in water - lower viscosity in aqueous suspensions - lower viscosity in PU polyol suspensions. más

    • Exolit® AP 435

      Exolit® AP 435 is a fine-particle ammonium polyphosphate (phase II) optimized for low viscosity in aqueous suspension and intumescent coatings. The product is largely insoluble in water and completely insoluble in organic solvents. It is colourless, non-hygroscopic and non-flammable. más

    • Exolit® AP 462

      Exolit AP 462 is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from ammonium polyphosphate by micro-encapsulation with melamine resin according to Clariant’s own method. Exolit AP 462 is a fine-particle white powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents. The product is non-hygroscopic and non-flammable. más

    • Exolit® AP 740 F

      Exolit AP 740 F is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. Exolit AP 740 F differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access. más

    • Exolit® AP 740

Exolit AP 740 differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access. más

    • Exolit® AP 742

      Exolit AP 742 is a non-halogenated, additive flame retardant based on ammonium polyphosphate, which develops its effectiveness through a phosphorus/nitrogen synergism. Exolit AP 742 differs in its mode of action from other flame retardant technologies (e.g. chlorine- or bromine-containing flame retardants and minerals) by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer by its heat-insulating effect and reduces further oxygen access. más

    • Exolit® AP 750

      Exolit AP 750 is a non-halogenated flame retardant based on ammonium polyphosphate as main component, which develops its effectiveness through phosphorus/nitrogen synergism. In contrast to similar competitive material, it shows high processing stability. Exolit AP 750 differs in its mode of action from non phosphorus-based flame retardants (e. g. brominated, chlorinated or mineral FRs like ATH) by achieving its effect through intumescence. Material containing Exolit AP 750 will foam on exposure to flame. The carbon-rich foam layer so formed will protect the polymer and in many cases the substrate below through its heat-insulating effect, reduces further oxygen access and prevents dripping in case of a thermoplastic based formulation. Beyond the primary effects on fire behavior such as reduction of flame propagation rate, rate of heat release, dripping behavior, residual lengths of test specimens after flame tests etc., positive secondary fire effects such as low smoke density, no release of corrosive off-gases, lower formation of toxic smoke gases are of great interest. más

    • Exolit® IFR 36

      Exolit IFR 36 is a non-halogenated flame retardant based on ammonium polyphosphate, which develops its effectiveness through phosphorus/nitrogen synergism. Exolit IFR 36 differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat insulating effect and reduces further oxygen access. más
