Two-Component Filter Adhesive – Excellent Vibration Resistance & Fatigue Resistance

The main component of two-component filter adhesive is polyurethane, a polymer known for its flexibility after curing. It includes two separate formulations designed to be used in combination. Our two-component filter adhesive is specially developed and designed for sealing and bonding plastic or metal end caps in products such as hydraulic oil filters, oil filters, fuel filters, and air filters. It features high bonding strength, chemical resistance, low-temperature curing, good elasticity and flexibility, and can adapt to the complex working conditions of automotive filters, resist vibration and impact. Besides, it is safe and reliable, and has a simple application process.

As an expert in the field of adhesives, PLM Filter has always worked with partners to develop innovative solutions that better meet industry applications, and we are always at your service.

Professional Advice

In the field of two-component filter adhesive for automotive filters, selecting an appropriate product type requires full consideration of various factors, such as bonding strength, impact resistance, and operability. To help you quickly find the product type you need, we will make recommendations based on your specific application and provide full-process technical support. Specific factors to consider when choosing an adhesive:

  • First, bonding strength. During operation, filters are subjected to various vibrations and impacts, requiring high-strength bonding performance.
  • Secondly, impact resistance. Filters undergo certain deformations during operation, so selecting an adhesive with appropriate elasticity and flexibility can prevent bonding failure due to vibrations and impacts.
  • Additionally, consider the working time and curing time of the adhesive to ensure there is sufficient time for adjustments during installation, while also allowing for quick curing to improve production efficiency.

We have carefully selected three types of products that meet the requirements: LM1541, LM1641, and LM1645. Among them, LM1641 offers the best cost-performance ratio, LM1541 has the strongest bonding capability, and you can choose based on your specific application. We are committed to providing you with the most professional services and the highest quality products, and we look forward to cooperating with you. If you have any questions or needs, please feel free to contact us.
