WEBAC_® B40: accelerator for EP injection resins

Epoxy injection resins are used for structural bonding. WEBAC EP resins are characterized by their high adhesive tensile strength and inherent strength. This ensures that even the smallest cracks can be permanently bonded – in concrete and in masonry. Compatibility with concrete, steel, masonry mortar, foil and cable sheathing is one advantage of WEBAC EP injection resins. 

The reaction time of EP injection resins depends on the temperatures of material and structural elements. The reaction is faster at higher temperatures and slower at lower temperatures. The reaction speed of epoxy resins can be reduced by adding an accelerator for EP injection resin. 
 

The accelerator for epoxy injection resin WEBAC_® B40 reduces the workable life of EP resins

WEBAC_® B40 is an accelerator for WEBAC epoxy resins WEBAC_® 4110, WEBAC_® 4120 and WEBAC_® 4170. Example: the epoxy resin WEBAC_® 4110 has a working time of 100 minutes at 20 °C. When mixing the product with 1% of the accelerator for EP injection resin WEBAC_® B40 it is reduced to only 75 minutes. When adding 3 % of the accelerator for epoxy injection resin WEBAC_® B40 its working time is only 50 minutes and only 35 minutes when adding 5%.
