One Component Reactive Adhesive

Universal application, enables high performance D4 bonds.

KLEIBERIT 605.1.20 is a new type of flowable reactive adhesive based on STP. The adhesive is a real all-rounder and adheres to almost all materials. In addition to wood and wood-based materials, it easily bonds painted surfaces as well as many types of plastic and metal (without sanding).

An adhesive bond with KLEIBERIT 605.1.20 offers the highest resistance values of class D4
(tested according to DIN EN 204) and Watt 91 (tested according to DIN EN 14257).

The processing properties of KLEIBERIT 605.1.20 are excellent. The time ratio between pressing time and open time (setting time) is very balanced. This allows both comfortable and fast working. The adhesive is applied by spatula, brush or roller and can also be easily dispensed from the squeeze bottle.

All of these advantages make KLEIBERIT 605.1.20 a real problem solver that no workshop should be without!
