MECHANICAL PROPERTIES AND CORROSION PROTECTION OF CARBON STEEL COATED WITH AN EPOXY BASED POWDER COATING CONTAINING MONTMORILONITE FUNCTIONALIZED WITH SILANE
In the present work the MMT-Na+ clay was functionalized with 3-aminopropyltriethoxysilane (γ-APS) and incorporated in a commercial formulation epoxy-based powder coating in a proportion of 8 wt% and applied on 1008 carbon steel panels by electrostatic spray. Adhesion, flexibility, impact and corro...

| description | In the present work the MMT-Na+ clay was functionalized with 3-aminopropyltriethoxysilane (γ-APS) and
incorporated in a commercial formulation epoxy-based powder coating in a proportion of 8 wt% and applied on
1008 carbon steel panels by electrostatic spray. Adhesion, flexibility, impact and corrosion performance in salt spray
chamber tests were performed to evaluate the coatings. The presence of clay did not affect the mechanical properties
of the film, however greater subcutaneous migration was assessed after the completion of salt spray testing, which can
compromise the use of paints obtained as primers. |
