TB 738 – Primer cured rubber to metal

The TB 738 is a solvent-free superglue which consists of 1 component. This primer is a cyanoacrylate which cures at room temperature in 25-90 seconds depending on which surface it is applied to.

Apply the adhesive in a very small amount until it is sufficient to achieve high tear strength and adhesion.

The Threebond 7738 is used, for example, to bond cured rubber to various metal and plastic substrates. The TB 7738 can also be used with difficult to bond materials such as POM, PPS and PBT.
