1711 & 2520 Resorcinol (PRF) Resin System BS EN 301 Adhesive Price From£14.58

AKZO NOBEL
CASCO ADHESIVES

Phenol-Resorcinol Formaldehyde Resin

Suitable adhesive for fire door repairs
Fire door repair glue

There are various systems within the Casco range to meet varying application method and end user requirements. A typical system is as follows:

Cascosinol Phenol Rescorcinol Adhesive 1711 with Hardener 2520

 

The combination Cascosinol 1711 with hardener 2520 is approved by NTI, Norway, Otto-Graf insitut (FMPA), Germany, SKO/KOMO (DHBC N0. 32389), Holland for the Production of load-bearing timber structures.
The combination can also be used in door production, lamination, finger jointing and other applications in the wood working industry, where there is demand for high water and weather resistance for the joints. The combination has short pressing times even at lower pressing times.

Other Data

Properties of the bond-line
Cascosinol 1711 with hardener 2520 fulfils the requirements according to EN 301 (for glue type I and II, service classes 1, 2, 3), EN 391, EN 392 and DIN 68141.

Storage life
1711     6 months at 20°C in well closed packaging
2520    
6 months at 20°C in well closed packaging

If the packaging is left open when not in use the glue is susceptible to skin formation on the surface. To avoid this the packaging should be closed when not in use

Pot life in hours                         4½   2¼   1¼    2/3    ½
 
When preparing large amounts of glue mixture, it is recommended to cool the glue to 10-15°C and after that add the hardener to extend the pot life.

Wood temperature
The temperature should not be lower than 20°C.

Moisture content of the wood
8 - 14 %. For the production of laminated beams 10 - 12%
Planing of the wood
Newly planed surfaces give the best gluing result. For best result at laminated mean production the timber must be smoothly planed. For optimum bonding strength the planing should take place within 24 hours before gluing.

Glue spread
For production of laminated beams a minimum glue spread of 400-450 g/m² single-sided is recommended. A reduction of the glue spread, e.g. at very short assembly times, is only allowed to be done together with the Casco Products Technical Advisors, depending on the production parameters for the production line in question. This optimization implies that the set parameters are followed and that a continuous control of the adhesion quality is made by means of delamination tests. At HF gluing a glue spread of 250-350 g/m² single-sided is recommended. At other applications: 150-300 g/m².
 
Difficult-to-glue wood or hardwood may require double spreading in amounts of 150-200 g/m² on each side.

Pressing temperature
Soft wood can be glued at a joint temperature of 20°C. To be sure to obtain a good result heating of the glue joint to 30°C is recommended. When gluing hard wood the temperature of the glue joint must be at least 40°C. Constructions with tensions and hard woods require at least 60°C to obtain adequate strength. Lowest pressing temperature has to be tried out. After the pressure is applied the heating can start.

Pressure
Minimum 0,5 MPa for soft wood
Minimum 1,0 MPa for hard wood
 
In laminated beam production:
Minimum 0,7 MPa for 33mm lamellas
Minimum 0,9 MPa for 45mm lamellas

According to DIN 1052/1-A1 the maximum allowed thickness of lamellae is 42mm.

Pressing time
The pressing time depends on the temperature, the distance to the innermost glue joint, the glue spread, etc. The table below may be used as a guideline.
