Batimix Epoxy 200 LV

Description

BATIMIX Epoxy 200 LV is a 100% reactive, two-component material designed as a moisture insensitive adhesive and binder for numerous application needs. This high modulus material is available in low viscosity (LV), medium viscosity (MV), or gel (GEL) consistencies.

BATIMIX Epoxy 200 LV provides a faster cure time for bonding concrete, at temperatures ranging from 1°C to 16°C.

Main Purpose

BATIMIX Epoxy 200 LV is a multi-purpose product. It is suitable for the following applications:

• General adhesive
• Primer and sealer
• Bonding toppings
• Production of repair mortars by mixing it with sand.

At temperatures exceeding 25°C, the medium viscosity product (MV) is more suitable for the applications listed herein. The product is not recommended for use as a surface sealer over new concrete, nor at substrate temperatures less than 0°C.

Features

BATIMIX Epoxy 200 LV exhibits the following characteristics:

• High early strength at low temperatures
• Excellent adhesion for bonding together concrete, steel, ceramic, or wood.
• Forms a tough, wear and chemical resistant coating for industrial floor slabs
• Easy-to-use mix ratios by volume
• Designed for applications at temperatures of 4°C to 30°C
• Working time and cure time will decrease as temperatures increase, and conversely increase as temperatures decrease

BATIMIX Epoxy 200 LV is mixed with sand or other aggregates. It is used to produce epoxy repair mortars and epoxy repair concrete. Mix the epoxy resin unit (part A) with the hardener unit (part B) before adding the aggregates. Trowel the mortar into place. If the surface is too rough, a topcoat of either BATIMIX Epoxy 200 LV or BATIMIX Epoxy 200 MV can be applied. It is not intended to be used as an aesthetic coating nor for overhead anchoring.

Directions for Use

Surface Preparation: New concrete and masonry must be dry and at least 28 days old prior to application. Steel substrates must be prepared to a white finish prior to application. Remove dust and laitance from the surface and cracks with compressed air. Concrete surfaces must be roughened and made absorptive, preferably by mechanical means, and then thoroughly cleaned of all dust and debris. If the surface was prepared by chemical means (acid etching), a water/baking soda or water/ammonia mixture, followed by a clean water rinse, must be used for cleaning, in order to neutralize the substrate. Allow substrate to dry before applying BATIMIX Epoxy 200 LV. Do not apply over hardened primer or old epoxy without proper surface preparation nor over freestanding water.

Mixing: Mix BATIMIX Epoxy 200 LV at temperatures ranging from 16oC to 21oC using a low-speed drill and a mixing paddle to uniform color. Do not thin BATIMIX Epoxy 200 LV. Pre-mix Part A and Part B separately for about 1 minute each. Combine Part A and Part B in a 2 to 1 ratio by volume, then mix thoroughly for 3 to 5 minutes.

To make an epoxy mortar, gradually add clean, dry, 20/40 mesh silica sand to previously mixed BATIMIX Epoxy 200 LV and mix thoroughly for 3 to 5 minutes. The mix ratio of aggregate to mixed epoxy is approximately 3 to 1 by volume, but can be modified depending on the desired consistency of the mortar. The aggregate is to be added to the mix after Part A and B have been premixed.

It is recommended to scrape the bottom and sides of the containers at least once during mixing but to refrain from doing so once mixing has ceased as it may cause unmixed resin or hardener being applied on substrate, which will not cure properly. To avoid aerating when mixing, use drill mixing paddles.

Application: To bond fresh concrete to hardened concrete, apply BATIMIX Epoxy 200 MV by brush, roller, or squeegee to a well prepared concrete substrate. While the epoxy is still wet, broadcast clean, dry aggregate into the resin until the aggregate is no longer being saturated by the epoxy, applying on any area of aggregate that looks “wet” additional aggregate.

For anchoring bolts, dowels, pins, use BATIMIX Epoxy 200 MV or Gel as an epoxy or alternatively as a mortar to grout vertically-aligned anchors into a horizontal substrate. Ensure anchoring holes are free of all debris before grouting.

For patching and repairs, apply BATIMIX Epoxy 200 LV as a primer coat to the prepared concrete surface that needs to be repaired or patched. Subsequently, apply to the area an epoxy mortar prepared from BATIMIX Epoxy Mortar 200 LV or MV by trowel or spatula in 25 to 40 mm layers while the neat primer coat is still tacky. Ensure initial set is achieved before subsequent layers are applied.

For pressure injecting vertical cracks, upon ensuring no water is leaking from cracks, pump BATIMIX Epoxy 200 Gel into cracks using two-component pressure injection equipment. Start from bottom of the crack upwards moving from port to port, capping off ports as proceeding forward.

For treating horizontal cracks, by mechanical means ensure cracks are free of debris and water. If gravity feeding, pump BATIMIX Epoxy 200 LV until cracks are completely filled, and if pressure injecting follow instructions outlined herein above. Take necessary measures to ensure epoxy does not leak through.

For priming/sealing, apply BATIMIX Epoxy 200 LV by brush or roller to the prepared surface. Porous substrates may require a second coat. Place subsequent epoxy coatings, which may be required if applying on porous surfaces, after the prime coat has become tack free, albeit within 1 to 2 hours of prime coat application.

Cleaning: Clean tools, application equipment, spills immediately with acetone, xylene, or Methyl Ethyl Ketone (MEK) as once it hardens, removal of BATIMIX Epoxy 200 LV will need mechanical abrasion for removal.

Coverage Yield

Priming/sealing: about 10 m2/l of BATIMIX Epoxy 200 LV

For repair mortars, coverage ratios will hover from 1 to 2 m²/l (of mortar).

Coverage will vary depending on concrete surface texture and temperatures.
