Overview

KingBond EP100 is a slow cure, solvent-free epoxy resin bonding agent that is supplied in pre-weighted two component packs which when mixed together produce a medium viscosity epoxy adhesive. KingBond EP100 can be easily spread over old concrete or cementitious substrates to permanently bond freshly casted concrete or new mortars.

Applications

KingBond EP100 is a permanent epoxy adhesive for bonding fresh wet concrete/cementitious material to old concrete/cementitious surfaces, which is suitable for internal and external application

Advantages

High bond strength
Moisture tolerant; can be applied to damp surfaces
Slow cure, allows more time for subsequent works such as fixing steel reinforcements and erecting shutter
High strength
STANDARDS KingBond EP100 complies with ASTM C881, Type II & Type V, Grade 2, Class C

VOC	: < 50 g/ltr (complies with LEED) *Minimum and maximum overlaying times depend on the ambient weathering conditions. In general the new concrete/cementitious material should be only applied over tacky layer of KingBond EP100. KingBond EP100 is designed to have an overlaying time of 9 hours at 25˚C and 5 hours at 40˚C. This should allow for subsequent works such as steel reinforcement fixation and shutter erection.
