Permabond is pleased to announce the launch of its new structural acrylic adhesive, Permabond TA4660, which provides outstanding adhesion to nylon and metal substrates.
Permabond TA4660 is a two-part structural adhesive ideal for bonding filled and unfilled nylon. THere is no need for primer or surface pretreatment to form bonds that exceed the strength of the nylon. This 2:1 mix ratio, low odor, room temperature curing adhesive also bonds metals.
In fact, the shear strength data listed below shows that the nylon fails before the bond in most applications.
PA6: >10 N/mm² (>1450 psi) Substrate Failure
PA6,6: >6 N/mm² (>870 psi) Substrate Failure
PA6 30% GF: 14-18 N/mm² (2030-2610 psi)
Mild Steel to PA6,6: >10 N/mm² (>1450 psi) Substrate Failure
Aluminium to PA6,6: >10 N/mm² (1450 psi) Substrate Failure
It is important to realize that the above values were achieved with no primer or pretreatment. Furthermore, the bonds have good strength retention at high temperatures and absorb differential thermal expansion and contraction stress without causing the bond to fracture.
