This high modulus, medium viscosity epoxy resin is the perfect solution for bonding new, plastic concrete to existing concrete slabs and steel. • Provides exceptional adhesion • Easy to use 1:1 mix ratio • Moisture insensitive Applications • Bonding fresh concrete to hardened concrete • Anchoring bolts, dowels, or pins • General adhesive for concrete and masonry • Mix with dried silica sand to create a repair mortar Specifications/Application Standards: Complies with ASTM C881 Types I, II, IV and V, Grade 2, Class C Meets the requirements of AASHTO M 235 Coverage: For bonding, 1 neat gal yields 231 in³ of epoxy. The coverage rate as a bonding agent is approximately 60 to 80 ft 2 /gal, depending upon the texture of the existing slab. 1 gal of neat DURAL 452 MV epoxy mixed with 3 gal of dry 20/40 mesh graded, clean, dry sand will yield approximately 643 in³ of mortar. Note: Coverage rates are approximate. Actual coverage depends on temperature, texture, and substrate porosity. Specifications : At 75˚ F Compressive Strength (ASTM C 695): 7 days 12,200 psi Bond Strength (ASTM C-882): 2 days 2,230 psi 14 days 2,365 psi Mix Ratio (volume): 1A:1B Gel Time (ASTM C 881): 30 mins Viscosity: 4,400 cps Description : A 100% solids, two component, moisture insensitive epoxy resin system. Has a unique hi-modulus of elasticity which allows for structural bonding of dry and damp materials free of hydrostatic pressure. High structural bonding/ grouting adhesive. Easy mixing ratio of 1:1 for the two components. Excellent bond to damp surfaces, insensitive to moisture before, during and after cure. Fast setting; provides high early strength within 24 hrs. Cures as low as 40° F. Application : Designed to bond fresh plastic concrete to structural sound hardened concrete. Excellent structural adhesive for bonding hardened concrete to hardened concrete and other structural materials. May be used as an epoxy mortar for patching spalls on dry or damp surfaces. Also used for grouting bolts, dowels, and pins. Applicable Standards : ASTM C-881, Type I, II, IV, V; Grade 2, Class B & C, AASHTO M-235-86. Coverage : 1 gal. yields 231 in³. 1 gal. covers approximately 80 ft² on a smooth surfaces and 50–75 ft²/gal. on rough surfaces. Specifications : At 72˚ F Compressive Strength (ASTM D-695): 7 days 10,000 psi Bond Strength (ASTM C-882): 14 days 2,900 psi Mix Ratio (volume): 1A:1B Pot Life: 30 min Viscosity: 3,500 cps Thin Film, Open Time: 1 hr Masco Hi-Mod No. Size EU 2G452MV 2 gal unit, 25 lbs No. Size MS 2GHM 2 gal. unit, 25 lbs.
