Remmers Epoxy Crack Fix Kit – Crack filling transparent epoxy resin
Remmers Epoxy Crack Fix Kit – Crack filling transparent epoxy resin. Crack Fix is an unpigmented, epoxy resin binder for fast, frictionally coupled filling of cracks and false joints on cement screeds and concrete. Transparent, 2-component, liquid, epoxy resin on a bisphenol A/F base:
▪ Cures very quickly
▪ Cures thoroughly as of 3 °C
▪ Good penetration capacity
▪ Nonphenol and phenol-free
▪ Can be subjected to heavy mechanical loads
▪ Can be subjected to chemical loads
The substrate must be load bearing, form-stable and free of loose material, dust, oil, grease, marks from rubber tyres and other substances that could interfere with adhesion. The tensile strength of the surface of the substrate must be 1.5 N/mm² on average, compressive strength at least 25 N/mm².
The substrate must have achieved its compensation moisture balance and be protected from the penetration of moisture from behind, also during utilisation. The substrate must be prepared by suitable means so that it fulfils the requirements given above.
Waiting times between working operations at 20 °C should be at least 60 min. and max. 1 day. For waiting times longer then 24 hours, the surface of the last working operation must be broadcast with fire-dried quartz sand. The given times are reduced at higher temperatures and increased at lower
The temperature of the material, the air and the substrate must be at least 3 °C and max. 25 °C. Relative humidity should not exceed 80 %. The temperature of the
substrate must be at least 3 °C above the dew point temperature.
At 20 °C and 60 % relative humidity: Foot traffic after 1-2 hours, mechanical loads after 2 hours, full loading capacity after 1-2 days. At lower temperatures correspondingly longer. During the curing process (approx. 24 hours at 20 °C), the applied material should be protected from moisture; otherwise the surface may be disturbed and adhesion may be reduced.
