The new MUF 1255/7555Adhesive system
Casco Adhesives is first to launch melamine system 1255/7555, the fastest MUF system available on the market for constructive wood lamination.
In 2005, Casco Adhesives launched the very successful system MUF 1247/2526 with just 65-minutes’ pressing time at 20°C. In 2009, Casco Adhesives launched the next ultra-fast MUF system 1255/7555.
Casco Adhesives has received approval according to EN 301/302 from MPA (Materialprüfungsanstalt) in Germany for this new super-fast melamine system for constructive wood lamination. Applications include:
Laminated beams
Duo and trio beams
Solid-wood lamination
Wall elements
Cross-laminated timber
Due to the wide range of hardener ratios in separate applications which offers a very flexible system, this system gives a very fast set-up for load bearing construction. For mixed-in application, Casco Adhesives will go for 100/30 approval. Besides the very fast pressing time of about half an hour at ambient temperature, it also offers a very short after-curing time of 3 hours at 20°C and low formaldehyde emission. A test at Eco Institute shows very low VOC (volatile organic compounds).
This super -fast system will work excellently in presses like Springer, Rotoflex and Dimter which have high productivity due to short pressing times.
Looking ahead, for the new Leisse and HIT press systems, the system will be the perfect match. It also works well in RF presses.
Melamine system 1255/7555 together with "forward integration", a machine developed by Casco Adhesives, offers the customer highly cost-efficient production. The machine measures the temperature of the lamella surface and the ambient, and then calculates the shortest pressing time and the lowest glue amount necessary for the acquired assembly time. This ensures optimised production for the customer. It also has great potential in safety issues for recognising low-temperature lamellas.
The more rapidy a system operates, the more important the basic wood temperature is. The super-fast performance makes the 1255/7555 highly competitive to 1C PUR.
Melamine system 1255/7555 also has a very short pressing time at very low temperatures in most European countries the minimum temperature for producing constructive wood components is 20°C, although some producers still face low temperatures. The pressing time at 5ºC is as short as 2 hours 15 minutes, compared to one of the biggest PUR glues, which is about 2 hours. Regarding different wood species, Casco Adhesives’ MUF 1255/7555 has proven to work very well also on pine, larch and oak as well as beech. Formaldehyde emission of 1255/7555 100/200, pass F☆☆☆☆ according to JAS 235. ■
