- a curable resin such as a formaldehyde resin
- Important properties of an adhesive include adhesive strength, curing time and temperature, water-resistance and emission of formaldehyde.
- Urea based amino resins are condensates of carbonyl compounds, such as aldehydes, with urea or thiourea. Other compounds containing amino, imino or amide groups may also be co-condensed into the urea based amino resin.
- urea based amino resins refer to condensates of formaldehyde and urea giving urea-formaldehyde ("UF").
- Urea based amino resins are usually cured by using acidic hardener compositions. The water-resistance is moderate for UF resin based adhesives as compared with pure melamine-formaldehyde (“MF”) resin based adhesives. Therefore, the use of UF resins is usually limited to indoor applications.
- UF resin based adhesives It is known to improve the water-resistance of UF resin based adhesives by adding different melamine based compounds.
- an MF resin can be mixed into a UF resin thereby forming a melamine-urea-formaldehyde ("MUF") resin.

At ratios of 2.5 or less, the UF resin is said to be remarkably poor in stability and having poor mixability with the phenolic resin.
- the problem solved is how to achieve a thermosetting resin composition, which is stable for a long time at room temperature.

- the amino resin and hardener composition may be applied completely onto each other, partially onto each other, or without being in contact with each other.
- the surface of the wood based material with both amino resin and hardener composition applied is thereafter joined with another surface of a wood based material, which also may have been applied with both amino resin and hardener composition, thereby providing a good mixing of the amino resin and the hardener composition forming an adhesive system which can be cured.

The assembly was pressed at a temperature of 95°C and a pressure of 0.7 MPa for 160 seconds. Test pieces of 75x75 mm were cut out which were conditioned in an atmosphere at 20°C with a relative humidity of 65%, for 7 days. Thereafter, the test pieces were water-treated for 2 hours at 70°C and then dried at 60 C C for 3 hours. The laminates were tested for delamination according to the Japanese standard, JAS for flooring.
- Example 2 A melamine salt was used in a UF resin of the same type as in Example 1. The same experimental procedure was used as in Example 1 , except that the pressing time was much longer, and the temperature slightly lower. The weight ratio UF resin to melamine formiate was 8.
- a MF resin is not stable enough to be used as a component in a hardener composition according to the present invention.
- - A PF resin of a resol type does not form a stable hardener composition.
- Example 3 A UF resin (of the same type as in Example 1) was tested with a hardener composition comprising PRF and pTSA according to the invention and a conventional acid hardener.
- the emission of formaldehyde was measured according to an internal method (IAR 804, flask method).

- Pieces of 60x45 mm were cut out and put in a 0.5 chamber hanging above 50 ml of water. After 3 hours at 40°C the content of formaldehyde in the water was measured.
