Require a solution for bonding Al fins to Al tubes which will not impede heat transfer efficiency and which will be robust over a long duty cycle of environmental temperature and humidity and dry/wet cycles.

require this to be Solvent/VOC free.

Current product is Royal 15012 Silaprene Adhesive. This product will become non-useable due to its solvent base and local manufacturing location environmental regulatory copliance issues. Extremely high volume application. Requires fast-cure characteristics. Need alternative to current product ASAP for application testing .

Thank you
