Reliable Bonding and Sealing Solution for Automotive Lighting

In the automotive lighting industry, bonding and sealing performance directly affect product durability, safety, and long-term reliability. Vehicle lamps are exposed to complex working environments, including outdoor low temperatures, high heat near the engine compartment, vibration, humidity, and long-term weathering. To meet these demanding requirements, Weasy Automotive Lighting Hot Melt Adhesive is specially developed for bonding and sealing applications in vehicle lighting products.

Designed for Automotive Lighting Applications

Weasy Automotive Lighting Hot Melt Adhesive is widely used for the bonding and sealing of lamp bases and lamp covers in various vehicle lighting systems, including:

• Automotive headlights
• Motorcycle lights
• Electric vehicle lights
• Other vehicle lighting assemblies

The adhesive provides strong bonding performance on different lamp substrates, such as metal, glass, and plastic, helping manufacturers achieve stable sealing, reliable adhesion, and long service life.

Excellent Temperature Resistance and Sealing Performance

Automotive lighting components must perform reliably under both high and low temperature conditions. Weasy Automotive Lighting Hot Melt Adhesive offers excellent adaptability to temperature changes, ensuring stable performance in harsh environments.

It can withstand extreme cold in outdoor conditions as well as high temperatures near the engine compartment. Even after long-term use, the adhesive maintains strong bonding and sealing performance, effectively preventing problems such as delamination, water leakage, and sealing failure.

Compared with silicone and standard PUR hot melt adhesives, Weasy Automotive Lighting Hot Melt Adhesive offers a simpler and more efficient application process. It also provides excellent cost-effectiveness while maintaining outstanding sealing reliability, making it a practical choice for modern automotive lighting production.

Multiple Models for Different Production Requirements

To meet different processing conditions and performance requirements, the product line includes several models:

TB3061, TB3062, TB3068TE, and TB3097H

The main technical range includes:

• Softening point: 120°C–149°C
• Viscosity at 180°C: 4,000–55,000 cP
• Application temperature: 170°C–210°C
• Open time: 70–120 seconds

Different models are suitable for different temperature resistance requirements, bonding conditions, and production processes. This allows the adhesive to be flexibly applied in both manual operation and fully automated automotive lighting production lines.
