AI Technical Summary

Technical Problem

Existing resin-coated members face issues with either strong adhesion leading to difficult peeling or weak adhesion allowing corrosive media ingress, compromising corrosion resistance and waterproofness.

Method used

A resin-coated member design featuring a member body with a transparent polyurea resin layer and an adhesive layer between the member body and resin layer, where the adhesive layer is low-tack to balance peelability and adhesion, and may include extended portions, uneven surfaces, or fastening parts with specific adhesive configurations.

Benefits of technology

The design enhances peelability and adhesion in a balanced manner, preventing corrosive media ingress and facilitating easy resin layer removal without residue, thus maintaining corrosion resistance and waterproofness.

Abstract

To provide a resin-coated member with enhanced balance between the peelability and adhesiveness of a resin layer.SOLUTION: A resin-coated member 10 includes: a member 12 having a body 12a; and a resin layer 16 that covers the surface of the body 12a and is composed of a transparent polyurea resin. A low adhesive layer 14, composed of a low adhesive, is interposed between the body 12a and the resin layer 16 over the whole area.SELECTED DRAWING: Figure 1
