Prefere 4535 is a liquid melamine-urea resin adhesive, which is used together with the liquid hardener Prefere 5035 in the manufacture of glued laminated timber structures and for finger-jointing.
When the gluing is carried out in accordance with the instructions in this Technical Data Sheet, Prefere 4535 gives water- and weather-proof, gap-filling bonds, conforming to Adhesive Type I of the European standards for adhesives for load-bearing structures (EN 301 and EN 302).
The glue lines are light-coloured and do not darken over time.
Prefere 4535 is also well suited for a number of other bonding operations. It can be used for hot and cold bonding and for bonding under radio frequency glue line heating conditions.
Prefere 4535 has low formaldehyde content and therefore offers the possibility to maintain a healthy working environment and at the same time achieve glue bonds exhibiting minimal formaldehyde emissions.
Ensure that the surfaces to be bonded are smooth, clean and free from dust or other deposits.
Wood, plywood, laminated plastics should be of uniform thickness.
Prefere 4535 should be mixed with the Prefere 5035 – refer to technical data sheet for correct mixing ratios and application data.
Store in the original containers in a cool, dry place, at a temperature range of between 5°C and 10°C.
