PUR 1601- Ideal choice for fixing automotive switch wiring harnesses
With the increasing level of automotive electronics, more and more complex electronic devices are being integrated into cars, which poses higher challenges to the design and fixing requirements of automotive wiring harnesses. Automotive switch wiring harnesses not only need to provide stable power connections, but also need to adapt to complex working environments, with high durability and flexibility. Therefore, selecting appropriate adhesive materials to ensure stable and long-term reliability of the wiring harness has become the top priority for automotive manufacturers and suppliers.Among them, switch wiring harnesses are usually composed of various substrates such as PVC material, metal, plastic, etc. Traditional bonding methods or materials often fail to maintain sufficient stability when facing high temperatures, high humidity, bending, and long-term stress, resulting in problems such as loose, detached, or even broken connections in switch wiring harnesses. How to choose an adhesive that can provide strong adhesion on multiple material surfaces while withstanding repeated bending, aging resistance, and chemical erosion has become an urgent problem to be solved. Fixing of automotive switch wiring harnessChallengeBending stress: Automotive switch wiring harnesses often require bending and stretching, especially during installation and dynamic changes in vehicle operation, where the wiring harness needs to undergo frequent bending. Ordinary adhesives may crack or fail during repeated bending due to a lack of sufficient flexibility and elasticity. Therefore, choosing an adhesive with excellent flexibility and high elasticity has become crucial.Adhesive bonding of PVC material: PVC, as a common plastic material, has good electrical insulation and durability, but its surface is smooth and prone to forming an oxide layer, which makes it difficult for many adhesives to effectively bond. In the car environment, insufficient adhesion between PVC surface and other materials may result in the adhesive being unable to firmly fix the switch harness, thereby affecting the overall stability…
