Three Bond 7738 - CA-Kleber - hohe Schäl- & Stoßfestigkeit - 20 g Flasche

Three Bond 7738 CA adhesive overview

The Three Bond 7738 is a thixotropic CA adhesive based on Ethoxyethyl cyanoacrylate. The color is colorless to light yellow. As a semi-gel, this adhesive is particularly suitable for vertical surfaces.

With a viscosity of approx. 5 Pa·s (at 25 °C) and a density of approx. 1.08 g/cm³, it offers controlled flow and good adhesion on a wide range of substrates. The adhesive bond is characterized by high peel- and impact resistance and maintains its strength under moisture and temperature.

Suitable for porous & acidic substrates

The semi-gel form enables controlled adhesion on porous and acidic substrates. Even with moisture or temperature changes the bond remains strong.
