Sandblasting is recommended for optimum adhesion. Mixing Pour all the contents of the smaller hardener curing agent component Part B (amber liquid) into the larger resin component Part A (black) and mix thoroughly until an even grey colour is obtained. A low speed electric drill driving a large spiral mixer is required to enable rapid, thorough mixing. Placing Conbextra EP935 should be placed immediately after mixing to take full advantage of the limited pot life (working life). Conbextra EP935 can be poured to displace water. Conbextra EP935 can be placed in thicknesses from 12 mm up to 30 mm in a single pour when used as an underplate grout. Where the grouting gap beneath the base plate exceeds the maximum thickness allowed, then the grout can filled / bulked out with Conbextra Grout Aggregate to minimise exotherm heat build up. Filling / bulking out of the grout should not exceed a ratio of 2:1 grout to aggregate. The addition of aggregate will change the characteristics of the grout. Note: because ALL epoxy resins shrink during the time between mixing and solidification, it is necessary to provide a small reservoir (2 - 3%) of liquid to supply the volume lost. This reservoir should be no longer in section than the section being supplied, so that exothermic temperature rise is lower in the reservoir and the reserve liquid solidifies later than the body of the casing. Where Conbextra EP935 is used for bolt and anchor grouting, the holes into which the bolts or anchors are to be grouted must be clean and thoroughly flushed with clean water. Headed bolts or anchors and deformed bars are to be preferred over plain bars. This will ensure an effective bond at the bolt/epoxy interface. Please refer to the Conbextra Epoxy Grouts Application Guide for further information. This is available from the website or your local Parchem branch. INDEX 150 Cleaning All tools and equipment should be cleaned immediately after use with Solvent 10 before hardening of the epoxy. Hardened material can only be removed mechanically. Estimating Conbextra EP935 is supplied in 15 kg (8.4 litre) two component, pre-weighed packs. Storage Conbextra EP935 has s shelf life of at least 12 months when stored in a dry, cool environment (below 35°C) in unopened containers.
