Pure epoxy components are mixed at relatively close mixing ratios (i.e. UV Resin. Generally, the industry standard is a white resin and black hardener, but these colors are not important for performance—the resulting gray, without streaks, serves as an indicator the components have been proportionately mixed. Load time Epoxy acrylates can also achieve high characteristic loads and they can be specified in applications involving damp substrates or relatively low temperatures. This type of coating is normally used in heavy industrial areas and can be used to repair the cracks to other epoxy floors before laying different epoxy coatings. Unlike pure epoxy with its slow cure times, polyester resins cure through polymerization that is relatively fast—this means such products can be specified for lower temperatures (down to as low as 2 C [35 F]), and contractors who use polyester resins will find they can be loaded much sooner after being installed. When specifying any epoxy product, one must read the manufacturer’s printed installation instructions (MPII) to ensure one is not selecting an anchor or repair product that will have a dangerously compromised bond. 10:1), which are easily identified in side-by-side cartridges. Jim Collins, PhD, PE, is MiTek USA’s manager of engineering projects. Epoxy glue applied in a wet setting usually requires some other type of fixative to help the epoxy dry. Horizontal and overhead applications require a non-sag product so the installed does not experience epoxy dripping out of a hole. The epoxy group is characterized by its reactivity towards both nucleophilic and electrophilic species and it is thus receptive to a wide range of reagents or curing agents. After the gel time has expired, manipulating the epoxy will compromise the bond.
