REP-250 and HR-409 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-250 and HR-409 have been designed and produced for the applications of repairing and compositing building stones as well as epoxying in the temperature range of 15-65°C (recommended temperature 45°C).
One of the prominent features of REP-250 and HR-409 is penetration into small diameter seams (due to low viscosity and excellent polishability) and acceptable stability of optical properties against ultraviolet rays. REP-250 has better shockability and less penetration than REP-140.
