Epoxy.com Product #303

100% Solids Extra Low Viscosity Epoxy Injection Resin

DESCRIPTION

Epoxy.com Product #303 Low Viscosity Epoxy Injection Resin and Bonding Adhesive is a is a two component, 100% solids, moisture insensitive epoxy resin system, mixed at a 2:1 ratio, with a viscosity of light-weight oil. Product #303 exceeds the requirements of ASTM C 881 87, Types I, II, Grade 1, Class "B" and "C". Use neat (without filler) for grouting damp and dry cracks or as a penetrating sealer on concrete, and wood. May also be mixed with Epoxy.com Special Fillers (Products #72-75), to create epoxy mortars.

ADVANTAGES

Low viscosity permits easy flow crack grouting by gravity feed or pressure injection.
May be injected below water.
May be used in temperatures as low as 40°F (4°C).
High strengths.

APPLICATION PROCEDURES

Surface Preparation

Surface must be clean and sound. Interfaces of cracks must he free of dirt, laitance, grease, curing compounds and other foreign matter. Flushing with water through ports under pressure may be necessary prior to epoxy injection. Cracks may be damp or wet.

Mixing

Temperature of Epoxy.com Product #303 must he 40° F. or above at time of mixing. Stir each component separately before blending. Mix two parts by volume of Part A with one part by volume of B for three minutes with a low speed electric drill motor equipped with a mixing paddle.

Application

PRESSURE INJECTION:

Set ports at intervals that approximately equal the thickness of the member to be injected in inches. Ports may need to be placed closer together for very fine cracks, or may be slightly further for wider cracks. Seal between and around each port with Epoxy.com Product #5, or #6. Inject Product #303 from an epoxy injection machine or binary hand or pneumatic injection gun. For more information, consult Epoxy.com technical service department and/or visit www.epoxy.com/303spec.aspx.

PENETRATING SEALER:

Apply mixed material with rubber squeegee or roller, Allow time to penetrate. Squeegee off excess while still liquid.

PATCHING:

Apply neat Epoxy.com Product #303 to prime clean sound substrate. Mix blended epoxy with Product 72, 73, 74 or 75 Filler and trowel in place.

ANCHOR BOLT GROUTING:

Diameter of hole should be minimum of 1/2" larger than that of bolt.

Yield

One gallon of mixed Product #303 will yield approximately:

750 Cu. in. when mixed w/3 gallons Product # 75 - very pourable

925 Cu. in. when mixed w/4 gallons Product #75- self-leveling

1100 Cu. in. when mixed w/5 gallons Product #75 - masonry mortar

Limitations

Minimum substrate temperature must be 40° degrees F.
Do not thin.

CLEANING

All tools and equipment should be cleaned before the system gels. Use methyl ethyl ketone or any lacquer solvent.
