- APPLICATION NOTES:
➢ General: MC-Solid 1252 is specially formulated, solvent free, Moisture Insensitive, thixotropic grade of epoxy for bonding of vertical elements and precast segments in RCC or PCC structure to provide a water tight structural joint. MC-Solid 1252 hardens without shrinkage. MC-Solid 1252 possesses high bonding and high modulus of elasticity.
➢ Surface preparation: The surface to be applied must be clean, free of dust, laitance, loose particles, contamination and curing compound residues. The minimum concrete compressive strength necessary should be >25 N/mm², substrate pull off strength of 1.5 N/mm² is required. Please refer to our General application Guideline for more technical information.
➢ Mixing:
– MC-Solid 1252 is supplied in two packs – Resin and Hardener – Ready to use for easy on-site mixing. Empty the base and hardener completely by scraping sides of the can into a container and thoroughly mix for 2 to 3 minutes using a slow speed electric drill with a paddle attachment to obtain a homogeneous consistency. To complete the mixing the mixture is poured from one can to another and mixed again to ensure homogeneity.
– When used as a segment bonding adhesive, hand mixing is not suitable. Depending upon thickness of adhesive, the thixotropy can be also controlled by addition of suitable fillers.
– The adhesive is applied to the prepared surface of segments to both faces by means of suitable trowels, spreaders or spatulas to either one or both surfaces. Jointing should be done with the open time and pot life of the adhesive.
➢ New concrete casting will be done immediately after the application of MC-Solid 1252.
➢ Coverage rates of MC-Solid 1252 are dependent on texture, temperature and porosity of the substrates as well as product storage and application temperatures. Higher temperatures shorten pot life, whereas lower temperatures will extend it. The general rule of thumb is that a temperature change of ±10°C halves or doubles the pot life of the Epoxy. All the tools and tackles will be cleaned by using MC-Reinigungsmittel U solution. If it hardened then it should be removed mechanically.
