Permabond launches long open time adhesive

Rather than curing immediately upon application, TA4213 offers a 20-minute open time that facilitates bonding over large surface areas and allows precise alignment of parts, even in smaller applications. Its fast strength development once parts are joined means a reduced clamping time and greater production efficiency.

Highly thixotropic, the adhesive has a non-stringing, non-slumping consistency that is ideal for gap filling. It doesn't slump or sag after application, making it well suited for vertical substrates. Its rubber toughening lends it high impact and vibration resistance, resistance to crack propagation and the ability to bond dissimilar substrates with mismatched coefficients of thermal expansion.

TA4213 features special built-in adhesion promotion technology that allows it to bond through oily surfaces or oxide layers, such as those found on aluminium. This greatly simplifies surface preparation, with an acetone or isopropanol wipe enough to prepare the surface for bonding using TA4213.

Typical applications where this long open time adhesive is suitable for use include: bonding exterior bus and coach body panels; aluminium profiles and stiffeners; signage fabrication; storage tanks and tank repairs; building facades and architectural panels; shop fitting; sports equipment; and general metal fabrication.
