Sealing solution for automotive switch wiring harness: reliable protection with high flexibility, flame-retardant PUR 1602
In modern automotive electronic systems, switch wiring harnesses play a crucial role in signal transmission and power distribution. With the improvement of vehicle intelligence, the integration of wiring harnesses is higher and the wiring is denser. At the same time, it is also exposed to more harsh environments – high temperature, moisture, dust, oil stains, and vibration, any of which can lead to unstable signals or short circuits. Therefore, reliable sealing and protection of the switch harness ends have become an important part of improving the reliability of the entire vehicle. Application BackgroundDuring the mass production process, a certain automobile manufacturer found that the insulation performance of the switch harness connection was prone to decrease due to moisture intrusion and mechanical stress. Traditional single component sealants have the following problems in use:Slow solidification and limited production pace;Insufficient adhesion to plastic parts (especially POM);The sealing layer is prone to hardening and cracking under long-term thermal cycling.Therefore, the customer hopes to find a sealing material that combines high flexibility, flame retardancy, and excellent adhesion.Solution: PUR 1602 two-component sealing sealantThe PUR 1602A/B two-component polyurethane elastomer launched by ELAPLUS perfectly solves the pain point problem in automotive wire harness sealing with its unique molecular structure and environmentally friendly system.Industrial wire harness sealingIndustrial wire harness sealingProduct Features HighlightsMedium viscosity design: controllable flowability, no glue leakage in small gaps, automatic leveling after infusion;Excellent flexibility and weather resistance: After curing, it forms a highly elastic protective layer that can resist thermal expansion, contraction, and vibration impact;Strong adhesion: It has good adhesion to most metal, PVC, ABS, PA and other substrates,⚠️ Plasma surface treatment is required before using POM materials to enhance adhesion;Superior flame retardant performance: meets UL 94 V-0 level requirements and meets automotive safety standards;Environmentally friendly solvent-free formula: odorless, heavy metal free, production friendly materials;Excellent waterproof…
