FAQ

Perguntas Frequentes -Perguntas

Para quais substratos serve?+

Suitable for sandblasting and rust removal up to Sa2.5 grade on carbon steel and cast iron surfaces. The substrate must be free of oil, rust, and old paint; a roughness of Rz40-75μm is optimal.

Por que não pode ficar exposto ao tempo?+

O epóxi não resiste a UV e calcifica com exposição longa. Exige intermediária epóxi MIO e acabamento atmosférico para um sistema completo.

Qual primer ou acabamento devo combinar?+

We recommend using the same series of primers and topcoats from Kexin to ensure coating system compatibility and optimal performance. Kexin technical engineers can design a complete primer-intermediate-topcoat system solution free of charge based on your specific working conditions.

Como consigo uma amostra e um orçamento?+

Guia de aplicação

ApplicationProcess

Preparo de superfície

Limpe bem o substrato contra óleo e ferrugem. Granalhe o aço a Sa2.5. Pré-trate conforme a ficha. Ambiente 5-40 °C, umidade relativa<85%。

Primer / pré-tratamento

Escolher primer ou pré-tratamento conforme substrato e sistema. Misturar na proporção exata e controlar a espessura. Avançar após a secagem; pré-pintar áreas críticas.

Aplicação da camada principal

Aplicar a camada principal conforme o processo, controlando espessura, clima e flash-off para um filme uniforme sem escorrimento.

Curing process

Bake or air dry at room temperature until fully cured according to product requirements. Maintain a uniform oven temperature (±5°C) and gradually increase the temperature to avoid coating defects. For room temperature curing, ensure adequate ventilation and suitable humidity.

Inspection and Acceptance

We test all indicators including film thickness, adhesion, gloss, color difference, and chemical resistance. We conduct comprehensive performance testing according to relevant standards. After all tests pass, we issue a test report and quality assurance certificate, and ship the product in dust-free packaging.
