Case Study of Adhesive Used for Fixing Automotive Switch Wiring Harness | Fast curing, flexible and bending resistant, PVC sticks firmly and is not easy to crack!
In modern automobile manufacturing, the wiring harness system serves as a “neural network” for electrical signal transmission, responsible for connecting and controlling the electronic systems of the entire vehicle.In actual assembly, the fixing of switch wiring harnesses is particularly crucial – it is necessary to ensure firm adhesion while maintaining reliability under frequent bending or vibration conditions.Today, we will take you through a typical case to learn about a high-performance adhesive suitable for fixing automotive switch wiring harnesses – PUR 1601. Application scenariosIn the assembly process of automotive switch wiring harnesses, the wiring harness material is mostly PVC (polyvinyl chloride), which has a low surface energy. Traditional adhesives are prone to problems such as weak adhesion and cracking after bending.The customer’s requirements are as follows:one ️⃣ Can firmly adhere to PVC without detachmenttwo ️⃣ Bending 10 times without cracking, ensuring fatigue resistance performancethree ️⃣ Fast curing speed, suitable for automated dispensing production linesRecommended solution: PUR 1601 two-component fast curing polyurethane adhesivePUR 1601 A/B is a two-component solvent-free room temperature curing polyurethane adhesive designed specifically for the electronics and automotive assembly industries, with three core advantages: flexibility, strong adhesion, and fast curing.✅ Product Advantages Overview:Rapid curing: It can be cured and formed in a short time at room temperature, greatly improving production efficiency.Excellent PVC adhesion performance: can firmly bond with various substrates such as PVC, metal, rubber, etc.High flexibility and bending resistance: After curing, it can withstand multiple bending without cracking, suitable for dynamic parts.Excellent aging resistance and chemical properties: can resist oil stains, moisture, and thermal aging environments for a long time.Low VOC formula: compliant with ROHS/REACH environmental regulations, safe and odorless.Suitable for multiple processes: machine dispensing or manual mixing operation, strong compatibility.Application testing verificationIn the customer’s on-site test, after fixing the PVC wire harness with PUR 1601, the sample…
