REP-139 and HR-501 have been specially designed and produced to improve the processing of construction stones. Among their features are very low viscosity, high curing (reticulation) speed, very high transverse joint density, and properties Excellent mechanical properties also indicated acceptable stability of optical properties against UV radiation.
REP-139 and HR-501 have been designed and produced for repair and composite building stone applications in the hot seasons of the year and are used when speed is important but color change is not so important.
One of the prominent features of REP-139 and HR-501 is penetration into small diameter seams (due to two features of low viscosity and excellent polishability) and acceptable stability against ultraviolet rays.
This product is faster than REP-139 and HR-500.
