Three Bond 7721 - CA-Kleber

Three Bond 7721 CA Glue at a Glance

The Three Bond 7721 CA glue is a low-odor ethoxyethyl cyanoacrylate adhesive that offers very fast bonding with reduced bloom effect. The color of the glue is colorless to pale yellow, enabling an unobtrusive bonded joint. It is particularly suitable for porous materials and achieves high strength on metal, wood, paper, and fabric.

With the minimal bloom effect, the bond remains clean while the adhesion sets quickly – ideal where short cycle times and precise contours are required.

Reliable Bonding of Porous Materials

The adhesive penetrates porous surfaces, ensuring a robust bond even on uneven structures without visible white blooms.

High Strength on Metal, Wood, Paper and Fabric

On metal, wood, paper, and fabric, the adhesive provides high shear and tensile strengths and maintains its performance even at moderate temperatures.
