A yet2 client seeks multi-material bonding technologies that can effectively perform in low temperatures (0°F/-17.8°C). A successful solution will be able to bond thick flexible sheets (in a range of different sizes) made from a variety of different materials (e.g., fiberglass, low surface energy substrates, and other construction materials) to one another. Cost effectiveness at high volumes and ease of installation will also be highly prioritized. Solutions such as, adhesives, sealants (which may include formulations) and mechanical connection mechanisms (e.g., fasteners etc.) are of interest.
Ideally, bonding technologies must:
- Have a fast installation speed, ideally within 15 seconds.
- Have a minimum bond strength of 25lbs/sq inch (172 kPa) between 20°F – 150°F (-6.7°C – 66°C) once cured/assembled.
- Be insoluble
- Be thermal shock resistant
- Safe to use for installers with regards to chemical exposure and mechanical safety (i.e., cuts or abrasions).
- Not require specialized tools during installation – any solutions should be able to cut with no more than a utility or hook knife during installation.
- Minimally interfere with the profile/geometry of the bonded components.
- Have 20 – 30yrs durability
- Be thermally stable up to 190-200oF and non-flammable.
- Must not permanently oxygen cure.
Ideally, bonding technologies should:
- Have a minimum bond strength of 50lbs/sq inch (345 kPa) between 0°F – 180°F (-17.8°C – 82°C) once set.
- Cost effective for large scale use
- Produce minimal waste
- Not produce significant VOCs
- Not produce additional safety concerns in the plant
Possible Solution Areas Include
(but are not limited to)
- Mechanical connection mechanisms
