Nurnberg, Germany (8 May 2007) - Celanese Corporation today announced the commercial launch of a new D4-rated ready-to-use PVAc-based wood adhesive that delivers performance in the most challenging outdoor environments. The patented technology, Mowilith® LDL 1400 W, is suitable for window frames and other demanding exterior applications where a high level of heat and water resistance is required. The single-component emulsion is chemically-free of formaldehyde and has been shown to emit very low levels of formaldehyde in use. Celanese is the first raw material supplier to deliver a ready-to-use one-component D4 adhesive with the performance properties required for premium wood products.

According to Arnold van de Laak, marketing manager for adhesives at Celanese, the introduction of Mowilith LDL 1400 W represents the latest effort by Celanese to deliver the right combination of performance and value to wood adhesives manufacturers. “Adhesive performance is essential for the consumer perception of quality in premium doors and window frames. At the same time, these wood products face significant challenges in outdoor environments, as they are exposed to temperature extremes and other weather-related damage. Mowilith LDL 1400 W delivers adhesive performance that easily meets and exceeds the specifications for these premium wood products,” he said. “The real technological breakthrough with Mowilith LDL 1400 W, however, is the product form. As a single component, ready-to-use product with a very favorable environmental profile and a long shelf-life, it is one of the most user-friendly adhesives you will find on the market,” van de Laak added. Celanese also offers a two-part version of this technology with its Mowilith LDL 2530 W product.

Patented new chemistry delivers advantages

Mowilith LDL 1400 W is designed as an aqueous vinyl acetate homopolymer dispersion with crosslinking capabilities. The all-new technology is stabilised with polyvinyl alcohol. Tests conducted according to DIN EN 205 actually show that Mowilith LDL 1400 W performs as well as or better than competitive products made with separate cross-linking systems. It easily achieves safe D4/3 and D4/5 values. The shear resistance of wood joints measured according to WATT 91 also gives values higher than the required 7 N/mm². Beyond this, Mowilith LDL 1400 W behaves like a premium wood adhesive, delivering a fast increase in bond strength at room temperature and at higher pressing temperatures. The polymer dispersion carries the Rosenheim certificate based on standardised D4 and Watt 91 test protocols. Adhesive product formulators will also appreciate the handling characteristics of Mowilith LDL 1400 W, given that it has a minimum shelf life of six months from the dispatch date when stored at room temperature under normal conditions.
