Solution for Sealing Motorcycle and Automotive Controllers – PUR 1680 Quick Curing Version

In today’s world where motorcycles and cars are increasingly digitized, controllers, as the core component of the “vehicle brain,” undertake key functions such as power management, drive control, and signal processing. The working environment is extremely harsh – external factors such as high temperature, humidity, oil pollution, vibration, electromagnetic interference, etc. can all cause electronic component failure. Therefore, selecting sealing materials with stable performance and high reliability is a key step in ensuring the long-term stable operation of the controller. 1、 The Importance of SealingElectronic controllers continuously generate heat during operation and are exposed to vibration and humid environments. Sealing materials not only provide insulation, waterproofing, moisture resistance, and shock protection, but also need to balance thermal conductivity and long-term reliability.For the fields of motorcycles and automobiles, a highly fluid, easily permeable, and stable curing sealant is an ideal choice to ensure the performance of controllers.2、 Glue requirementsIn the sealing process of motorcycle and automotive controllers, customers have raised the following requirements:one ️⃣ The operation time is about 1 hour, which is convenient for sealing, leveling, and defoaming;two ️⃣ Colloids need to have excellent fluidity and permeability, and be able to fully fill small gaps and complex structures;three ️⃣ After curing, it should maintain good flexibility and durability, be waterproof and moisture-proof for a long time, and ensure stable adhesion between the circuit board and the shell.3、 Recommended product: PUR 1680 Quick EditionPUR 1680 Quick Edition is a two-component solvent-free room temperature or heat cured polyurethane potting material designed specifically for electronic control modules, car control boxes, power modules, and other structural applications.Product FeaturesThe operable time is about 1 hour, meeting the medium speed production cycle;Low viscosity flow system, easily penetrates the gaps between windings, pins, and components;Excellent insulation and waterproof performance, effectively protecting circuit boards from moisture erosion;High flexibility…
