Anti-yellowing dry laminating adhesives LIS-7011
This is an acrylic adhesives that is rare in the industry. It exhibits superior performance compared to urethane adhesives in terms of hydrolysis resistance, oil resistance, and yellowing resistance.
Development background
In recent years, laminating adhesives in the industrial materials field has seen growing demand for EVs (Electric Vehicles) and FCVs (Fuel Cell Vehicles) and environmental considerations, and the need for long-term durability in harsh environments is increasing.
The need for long-term durability is increasing in the industrial materials field.
laminating adhesives Urethane-based adhesives is widely used in the production of EVs and FCVs (Fuel Cell Vehicles) from the viewpoints of ease of handling during production, freedom of product design, and cost. On the other hand, hydrolysis resistance is an issue for some applications that require long-term durability.
We have recently developed an acrylic resin-based laminating adhesives "LIS-7011" that achieves a breakthrough in hydrolysis resistance by applying the acrylic resin technology of our group company, TOYOCHEM CO., LTD.. While the acrylic resin-based adhesives is resistant to various kinds of resistance, it is characterized by its rigid and brittle nature. However, this newly developed product has achieved a flexible coating film design through a special formula design.
Characteristics
- Excellent hydrolysis resistance
- Excellent weather and heat resistance
- Excellent oil resistance
Application example
- Automotive components (insulating sheets, composite materials for gaskets, acoustics, battery surroundings, heat-resistant/durable components)
- outdoor building materials
- Electronic device related
electric car motor with suspension
electric car interior
electric car chassis
