ASTM-C-881: Types I, II, IV & V, Grade 2, Classes B & C
Meets USDA specifications for use in food processing areas
|
A solvent-free, moisture-insensitive, 100% solids, medium-viscosity, two-component epoxy bonding agent and injection resin specifically formulated for load-bearing applications where higher tensile strength is required. Recommended for structural crack repair for larger cracks: 0.007-0.030 in/0.18-0.76 mm.
PRO-POXY(TM) 204 meets ASTM-C-881, Types I, II, IV & V, Grade 2, Classes B & C. It also meets USDA specifications for use in food processing areas. An excellent epoxy adhesive for use in crack grouting by pressure injection or gravity-feed and for making epoxy mortars and grouts. PRO-POXY(TM) 204 is slightly thinner than PRO-POXY(TM) 200.

Application
SURFACE PREPARATION: Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove surface contaminants e.g. dust, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials. Concrete: Sandblast or use other approved mechanical means. Steel: Sandblast to white metal finish.
MIXING: Pre-mix each component thoroughly. Place 1 part by volume of component A and 1 part by volume of component B into a clean pail. Mix thoroughly for 3 min. with low-speed drill and Jiffy type mixer (400-600rpm) until uniformly blended. Mix only the quantity that can be used within its gel time.
TO BOND FRESH CONCRETE TO HARDENED CONCRETE: Apply by brush, roller, broom or spray to cured concrete substrate. Place fresh concrete while PRO-POXY(TM) 204 is still tacky. If coat of PRO-POXY(TM) 204 loses tackiness before pouring concrete, roughen epoxy surface to create bonding profile. Recoat with additional PRO-POXY(TM) 204 and proceed.
TO BOND OLD TO OLD CONCRETE: Apply the mixed PRO-POXY(TM) 204 by brush, roller, broom or spray to the substrate working in for positive adhesion. While coating is tacky, join the coated substrates and secure firmly into place. Glue-line should not exceed 1/8 in./3.2 mm.
TO STRUCTURALLY REPAIR CRACKS BY GRAVITY FEED: If cracks reflect through slab, seal underside of cracks by buttering crack with PRO-POXY 300, PRO-POXY(TM) 300 FAST, or PRO-POXY(TM) 300 PASTE. Otherwise, pour neat PRO-POXY(TM) 204 into v-notched crack. Continue placement until crack is completely filled.
TO VERTICALLY ANCHOR REBAR, DOWELS, AND THREADED ROD: For efficient transfer of stress, the annular space around bolt should not exceed 1/8 in./3.2 mm. The depth of embedment is typically 9 times the bolt diameter. Grout with neat PRO-POXY(TM) 204.
TO PREPARE EPOXY MORTAR: Slowly add 1 1/2 parts by loose volume of an oven-dried aggregate to 1 part of the mixed PRO-POXY(TM) 204. Mix until uniform in consistency and color.
|
Limitations
Minimum substrate temperature is 40°F (5°C).
Do not thin. Solvents will prevent proper cure.
Use oven-dried aggregate only.
Minimum age of concrete must be 5-7 days, depending on curing and drying conditions, for mortar.
Do not seal slabs on grade with product. PRO-POXY(TM) 204 is a vapor barrier.
Maximum epoxy mortar thickness is 1.5in/3.8 cm per lift.

Cleanup
EQUIPMENT: Uncured material can be removed with Unitex CITRUS CLEANER or other approved solvent. Cured material can only be removed mechanically.
MATERIAL: Collect with absorbent material. Flush area with water. Dispose of in accordance with local, state and federal disposal regulations.
|
First Aid
EYE CONTACT: Flush immediately with water for at least 15 minutes. Contact physician immediately.
RESPIRATORY CONTACT: Remove person to fresh air.
SKIN CONTACT: Remove any contaminated clothing. Remove epoxy immediately with a dry cloth or paper towel. Solvents should not be used as they carry the irritant into the skin. Wash skin thoroughly with soap and water.
CURED EPOXY RESINS ARE INNOCUOUS.
