Kemko® 077 Large Void IR
Injection Resin – Large Void & Wide Crack Structural Epoxy Adhesive Pressure Injection
Description
KEMKO® 077 Large Void IR is a two-component, low viscosity, low exotherm (isothermic), structural epoxy adhesive specifically designed for large voids, wide cracks/delaminations, gaps, honeycombs in concrete, and grouting of steel plates for external reinforcement with pressure injection grouting using KIP™ (KEMKO® Injection Process) System automatic meter, mix, and dispensing application equipment. For filling voids or cracks in excess of several inches to a cubit foot or greater it is recommended, when possible, to pre-pack the voids or wide cracks with uniformed size aggregate that has been washed, dried, bagged, and then pressure injected. Packing with aggregate will help increase the stiffness (compressive modulus) of KEMKO® 077. It bonds to dry, damp, wet, and underwater substrates. It contains no VOC’s (volatile organic compounds).

Features
KEMKO® 077 has a long working life and a low exothermic (isothermic) reaction (minimal heat generation during cure) that make it suitable for applications where a relatively large mass of adhesive is employed. The low exotherm cure characteristics, particularly when used in conjunction with pre-placed aggregate, minimizes heat build-up and associated volumetric shrinkage, and the liquid material shrinkage upon cooling and curing.
