PT44 Zap-RT Rubber Toughened CA Glue

Zap-RT is a highly specialised rubber-toughened cyanoacrylate, arguably the strongest adhesive in the Zap range. The unique formula is infused with microscopic rubber particles, allowing the cured bond to remain slightly flexible. This enables the joint to absorb mechanical shocks and withstand high-vibration environments without snapping or becoming brittle over time.

This exceptional durability makes it the definitive choice for highly demanding applications. It is widely regarded as the ultimate adhesive for RC vehicle tyres, securing rubber to plastic or chrome rims with a bond capable of surviving high-speed cornering and heavy impacts. Beyond radio control, it is invaluable for prop builders, drone engineers, and professional makers constructing armatures or structural components that must endure constant handling, weather exposure, or mechanical stress.

Despite its industrial strength, the medium-thick formula dries crystal clear. It is specifically designed not to mar or fog surrounding surfaces, preserving the aesthetic of glossy or chrome details. While you can use a standard CA accelerator to force an immediate set, allowing the adhesive to cure naturally over 20 to 30 seconds provides the maximum toughening benefit for critical structural joints.
