Durability of Two-Part Acrylics

Two-part acrylics will often show slightly improved durability over cyanoacrylates, particularly where the gaps are bigger and one of the substrates is not a plastic. However, two-part acrylics do not bond well to elastomers and here cyanoacrylates will show much better durability. 

For impact resistance and peel strength, the tougheners in two-part acrylics will be of major benefit and, since these adhesives will typically be of lower cost than UV adhesives or cyanoacrylates, they are often used for the larger applications. 

As with all of these adhesives, the durability will depend on many factors and it will always be necessary to chose an adhesive system (i.e., pre-treatment/cure speed/
