Application Description

Open for everything

A permanent resistance of the solid wood elements is essential due to the exposure of these products to outdoor conditions. The Jowat product portfolio with powerful D4 dispersions, EPI dispersions and PUR adhesives provides processors with the opportunity to meet different requirements.

Requirements for adhesive bonding today are higher than ever before. More and more building owners attach particular importance to the impact of construction products on human health and the environment.
Demand for wood windows therefore remains unbroken. Elaborate designs, long-lasting surface coatings and the combination with other materials facilitate classic wood windows with high resistance and at the same time visual appeal.
Apart from their characteristic, natural properties, wood windows are also increasingly becoming established as an ecological alternative. Wood has excellent carbon storage properties and therefore its use contributes to a climate-friendly environment.

The Jowacoll® dispersion adhesives with durability class D4 (according to EN 204/205) currently used in the manufacture of window scantlings are characterised by high bond strength and uncomplicated processing.
For even higher requirements with regard to water and temperature resistance, Jowat supplies dispersion adhesives based on emulsion polymer isocyanate (EPI). These adhesives provide superior strength due to a high degree of crosslinking, while also being easy to process like PVAc dispersion adhesives.

The Jowat portfolio allows processors to choose the right adhesive for the individual process. With the powerful Jowacoll® dispersion adhesives, Jowat supplies a multitude of alternatives for efficient bonding. The extensive product range provides solutions for different application technologies, whether by roller, blade, nozzle or pouring.
With extensive expertise in the industry, Jowat understands the requirements for the end products and is consistently developing its portfolio further.
