Abstract
Se describe una lámina de acero inoxidable apropiada para uso en la fabricacion de un componente de escape. La lámina de acero tiene por lo menos una superficie pretratada con un recubrimiento protector resistente a la deslaminacion a temperaturas de hasta aproximadamente 540 degree C, que incluye una porcion interna inorgánica y una porcion externa orgánica. La porcion inorgánica incluye por lo menos 50 mg/m² de un recubrimiento de conversion a base de cromo, que tiene un espesor no mayor de 0.02 mm. El recubrimiento de conversion contiene sílice en partículas, la relacion en peso de cromo a sílice está en el rango de 1:1 a 2:1. La porcion externa orgánica incluye una pintura de silicona que contiene 40-60% en peso de resina de silicona. La pintura de silicona se seca a una temperatura menor de 300 degree C en menos de un minuto y luego se recubre con un copolímero de un acrílico termoplástico y un lubricante o una olefina polimérica. El copolímero acrílico contiene 5-70% en peso del lubricante y la olefina polimérica contiene 90% de resina de olefina. Luego la lámina recubierta con lubricante se seca a una temperatura de 25-120 degree C por menos de un minuto para formar un espesor de película de 0.0005 - 0.020 mm, que tiene un coeficiente de friccion no mayor de aproximadamente 0.05 y un peso de 10 - 5000 mg/m². La pintura de silicona seca cubierta mediante la película de lubricante seca está libre de adherencia o pegajosidad, es impermeable a la humedad, el aceite y a los desechos y los semejantes, la lámina de acero recubierta de silicona está preparada para su formacion en un componente de escape con mínima deslaminacion de la pintura de silicona seca, sin lubricante externo adicional que se requiere sobre la lámina.
