Embodiment 1

[0104] Example 1: Activation method of hydrolyzed surface

[0105] The examples illustrate that the improved SIJA intercoating adhesion compared to the untreated samples results from activation of the coatings prior to overcoating. The intercoat adhesion provided in this case was similar to that of the samples reactivated by sanding.

Embodiment 2

[0106] Example 2: Activation method of oxidized surface

[0107] The examples illustrate that the improved SIJA intercoating adhesion compared to the untreated samples results from activation of the coatings prior to overcoating. The intercoat adhesion provided in this case was similar to that of the samples reactivated by sanding.

Embodiment 3

[0108] Example 3: Activation method for reducing surfaces

[0109] The examples illustrate that the improved SIJA intercoating adhesion compared to the untreated samples results from activation of the coatings prior to overcoating. The intercoat adhesion provided in this case was similar to that of the samples reactivated by sanding.

Abstract

The present invention relates to a method of activating an organic coating to enhance adhesion of the coating to a further coating and / or to other entities comprising applying a solvent and a surface chemistry and / or surface topography modifying agent to the organic coating. The invention also relates to a coated substrate having an activated coating, wherein the adhesion of the coating to a further coating and / or other entities has been enhanced by application of a solvent and a surface chemistry and / or surface topography modifying agent to the coating. The invention further relates to an activation treatment for an organic coating to enhance adhesion of the coating to a further coating and / or to other entities comprising a solvent and a surface chemistry and / or surface topography modifying agent and a method for the preparation of the activation treatment.

Description

technical field [0001] The present invention relates to a method of activating an organic coating, a coated substrate having a washcoat and an activation treatment agent for the organic coating. In particular, the activation method improves the adhesion of the organic coating to other coatings and / or to other entities. Background technique [0002] Organic coatings are often used to protect material surfaces from accidental damage, abrasion, chemical attack, and degradation from the environment or in use. Organic coatings are also used to enhance the aesthetic and / or optical properties of objects or parts. [0003] The surface properties of many coatings change significantly during drying, curing and / or aging, becoming more inert than would be predictable based solely on the chemical properties of their individual components. While this phenomenon provides the coatings in part with chemical resistance, impact strength, abrasion resistance and durability, it also complicate...
