It has been developed to bond low surface energy plastics such as polypropylene and polyethylene - with no primer or expensive surface treatment required. It can also be used to bond a wide variety of other materials such as metals and composite materials and is ideal for bonding dissimilar surfaces. This product is similar to TA4610 but does not contain micro beads making it suitable for joints with smaller gaps. *Substrate failure was observed.

Fully cured lap shear specimens conditioned to pull temperature for 30 minutes before testing at temperature. TA4611 can withstand higher temperatures for brief periods (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed. The minimum temperature the cured adhesive can be exposed to is -55°C depending on the materials being bonded._ Additional Information This product is not recommended for use in contact with strong oxidizing materials. This product may affect some thermoplastics and users must check compatibility of the product with such substrates....
