ACCELERATOR-5000 is a special set accelerator for ISOFLEX-PU 500 that enables its application at low temperatures or in thicker layers. It is also increases the thixotropy and mechanical strength of ISOFLEX-PU 500. It is added to ISOFLEX-PU 500 to accelerate its setting. It offers the following advantages:
- It enables the application of ISOFLEX-PU 500 at low temperatures.
- It prevents the appearance of air bubbles when ISOFLEX-PU 500 is applied in thick layers.
- It allows ISOFLEX-PU 500 to set under low humidity conditions.
ACCELERATOR-5000 should be shaken before is opened and added to ISOFLEX-PU 500. They are then mixed and stirred with a low-speed mixer (300 rpm), so that the mixture becomes homogeneous. Excessive stirring should be avoided, in order to prevent air entrapment.
ISOFLEX-PU 500 should be applied immediately after the addition of ACCELERATOR-5000 as the mixture’s pot life is approx. 15 minutes.
Application at temperatures between -10oC and +8oC.
Before application, the containers of ISOFLEX-PU 500 and ACCELERATOR-5000 must be sotred in a heated space (at temperatures > +18 oC) for at least 24 hours. At low temperatures, thick application layers should be avoided, while it is also essential to add SM-28 special solvent (approx. 5% by weight).
Application at temperatures between +8oC and +30oC.
After mixing ISOFLEX-PU 500 with ACCELERATOR-5000, it is optional to add SM-28 special solvent (2-5% by weight), as the accelerator increases the viscosity of ISOFLEX-PU 500.
Application at temperatures > +30oC.
The use of the accelerator at temperatures higher than 30oC should be avoided, as the pot life of ISOFLEX-PU 500 will be extremely short.
