Needs Title
Bio-based Adhesive for Water and Temperature Resistant Bonding in Interior Car Components or Structural Parts
Description
BMW Group is seeking natural and recyclable adhesives or gluing solutions for use in manufacturing of automotive components, especially adhesives for wood-wood laminates. Adhesives should not debond up to 90°C or after contact with water.
Background
BMW Group is increasingly transiting from linear economy to circular economy to enhance the sustainability of their products. The initiative is to apply a circular economy framework, which promotes renewable feedstocks for production of future products thereby reducing the environmental life cycle burden of car manufacturing. BMW strongly feels this approach would align with consumer demand for sustainable products.
One such example is the adhesive system, which are currently based on fossil materials. These are often hard to separate after the end of life and recycling of glued automotive parts is often not possible. In contrast to today's predominant fossil-based adhesives, the product we are looking for should be based predominantly or entirely on natural materials, particularly the adhesive itself, possibly the hardeners and additives. As the adhesive system may be used in laminating and coating of components or in fraught structural car components the strength characteristics should be comparable with conventional solutions such as MUF- or PF-Resins, PUR/PMDI or Epoxy. With further development the proposed glue will be used on a large scale in industry. This has an impact on how the glue is applied as well as gluing characteristics such as viscosity, time, temperature, and pressure.
Key success Criteria
BMW Group is seeking innovative adhesive systems that fulfill the following criteria:
- Bio-based: The adhesive, or the hardeners or the additives must be derived from renewable feedstock and therefore has inherent character of recyclability.
- Be stable up to 90°C and in contact with water
- Main focus:
- wood to wood bonding for laminates
- Additionally, to bond:
- wood to metal (e.g., Steel or Aluminum)
- wood to polymers (e.g., PA or PP or ABS or PVC or PC)
- Sufficient mechanical strength and durability properties (like conventional systems e.g., PUR adhesives or epoxy resin)
- Applicable on conventional materials as well as on renewable materials
- Advantageous but not essential:
- suitable separation option for recycling after the end of life
- or bio-degradable after the end of life
- or debonding of mixed materials
- With further development:
-
- production scalable to cover industrial demands
- application process on an industrial scale
- competitive in terms of pricing
- Supported by material data sheet including data on low CO2e footprint, ideally third-party certification
Possible Approaches
- Any adhesive system that is based on sustainable materials
- Both early-stage solutions and mature solutions (suitable for commercial application in less than 3 years)
Approaches not of Interest
- All predominantly fossil-based materials
- Technologies that do not have the perspective to meet the standards of the automotive industry
- Technologies that are toxic or harmful to the environment in any other way after the curing process
- Solutions that do not meet the above success criteria
