The automotive wiring harness is the blood vessels and nervous system of the automobile. The requirements of automotive wiring harness are also relatively high, need to use high temperature resistance, oil resistance, corrosion resistance materials.
 
 Using PE as a wire harness, the product has better mechanical properties and stability, so it is more widely used. But there is a difficult problem in the assembly. We will find a situation, whether it is silicone, UV glue, or structural glue, the original plastic glue is very solid, in the PE encountered Waterloo, no stickiness, just a touch off. This is because the PE material is characterized by high chemical stability, the general adhesive in its surface wetting ability is poor, it is difficult to form a stable attachment. So is there any glue that can firmly attach to PE and form a long-term and stable waterproof seal? This is the concern of so many engineers.
 
 Xiaobian recently found a magical glue ENIENT ®EG1023, which can activate the PE surface and make it produce more active molecules. At the same time, the colloid has high permeability. The molecular chain of the glue can penetrate into the molecular gap on the PE surface, thus forming an intermolecular stable van der Waals force, which can reach 4 ~ 5 Mpa.
 
 So what's this glue like? What about the life and stability of the bonding?
 
 This is a modified rubber system, with a soft and elastic characteristics. And because the rubber itself is a chemical corrosion resistance and aging resistance are relatively good, so this glue has many advantages such as waterproof, insulation, aging resistance, chemical corrosion resistance and so on.
 
 This glue is particularly suitable for use in PE wire harness, as reinforcement, fixing, waterproof sealing and other purposes. It not only has good adhesion to PE, but also for PVC, ABS, PC, PS, PMMA, PA, PP, PE, HDPE, PBT, EVA and so on have extraordinary adhesion. Do you have any other glue problems?
