PU Foams

MAKROFLEX WHITETEQ PRO

1K WHITETEQ gun foam

Characteristics:

  • Very good filling  capabilities
  • Excellent adhesion on most materials
  • High thermal and acoustical insulation
  • Accurate dosage
  • Usable in low temperatures
  • Enhanced UV resitance

MAKROFLEX WHITETEQ is white polymer foam of a new generation polyurethane, based on purified & concentrated ingredients. The polymer purification (WHITETEQ Technology) allows convenient curing parameters and gives WHITETEQ foams it’s characteristic ice-white color, an extra-fine cell structure and enhanced UV resistance. The cured foam has highest thermal efficiency (up to 0,032 W/mK) and sound damping properties (63 dB). WHITETEQ technology also offers unrivalled low curing pressure for convenience in use and 25 % flexibility ensures a long-term insulation efficiency – compensating the movements of the seal resulted from e.g. thermal expansion. The perfect ratio of open and closed cells and mechanical strength makes it the perfect product for demanding insulation applications. The foam has excellent adhesion on most building materials like wood, concrete, stone, metal etc. Yield of the cured foam largely depends on working conditions – temperature, air humidity, available space for expanding, etc. At minus temperatures the expansion of foam is lower and curing time longer.

Product does not contain CFC-propellants.

How to use

PU Foams

Substrate preparation

  • Ensure substrates are stable, clean and free of substances likely to impair adhesion.
  • Moisturize mineral, porous substrates (brickwork, concrete,limestone) with water spray for enhanced adhesion.
  • Mask off adjacent areas with foil.

Can preparation

  • Application temperature (environment) of this product is +5°C to +30°C.
  • Store can preferably for at least 12 hours in room temperature. Limits for can temperature: +5 … +30 °C.
  • Shake the can vigorously before use (15 - 20 times).
  • Remove the plastic cap from the can and screw the can tightly onto the gun.
  • When working with the gun always keep the can upside down.
  • The outflow rate of the foam is controlled by pressing the gun trigger.

Application

  • Dispense the foam sparingly to avoid excess overflows. Repeat shaking regularly during application.
  • It is not recommendable to remove the can before it is totally empty. When replacing the can shake the new can vigorously. Unscrew the empty can and replace it immediately to ensure that there is no air left in the gun.
  • If you do not want to replace the can, remove the foam from the gun using PU foam cleaner. Hardened foam can only be removed mechanically.

 

Recommendations

Limitations to joint maximal width exist in regard of ambient temperature and humidity levels. In dry conditions (during winter time, in rooms with central heating etc.), in order to get best foam structure and foam properties it is recommendable to fill gaps and joints in several layers by the application of smaller foam strings (up to 3 -4 cm thickness) and slightly moisturizing between every layer.

Please use the applicator tested and approved by the producer of the can for best working experience!
