Batimix Epoxy 100 Gel

Description

BATIMIX Epoxy 100 Gel is a 100% reactive, two-component material designed as an adhesive and binder for numerous application needs. It is a non-corrosive material recommended for applications that require non-sag characteristics. This high-modulus material is available in low viscosity (LV), medium viscosity (MV), or high viscosity (Gel).

Main Purpose

BATIMIX Epoxy 100 Gel is a multi-purpose product. It is suitable for the following applications:

• Bonding concrete, masonry, steel, or wood
• Anchoring bolts, dowels, and pins
• Sealing cracks
• Production of repair mortars by mixing with sand

The low viscosity product (LV) is primarily used for injection, priming, and sealing; the medium viscosity (MV) for bonding applications and high viscosity (Gel) for anchoring.

Features

BATIMIX Epoxy 100 Gel exhibits the following characteristics:

• Very-strong adhesion to various construction products
• Easy to use mix ratios, by volume
• Designed for applications at temperatures of 10°C to 30°C
• Working time and cure time decrease as temperatures increase and increase as temperatures decrease

BATIMIX Epoxy 100 Gel is mixed with sand and other aggregates to produce epoxy repair mortars and epoxy repair concrete. It should not be used as an aesthetic coating or for overhead anchoring.

Properties

• Gel time (ASTM C 881) : 30 min
• Working time : 90 min
• Bond strength (ASTM C 882): 17 MPa (2 days) and 22 MPa (14 days)
• Water absorption at 24 hours (ASTM D 570) : 0.2%
• Compressive modulus (ASTM C 695) : 4100 MPa (7 days)
• Compressive strength (ASTM 695) : 70 MPa

Health and Safety

BATIMIX Epoxy 100 Gel is not a hazardous material. However, do not heat it with open flames. It should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Compliance with Standards

BATIMIX Epoxy 100 LV complies with ASTM C881 Types I and IV, Grade 1, Classes B and C; BATIMIX Epoxy 100 MV complies with ASTM C881 Types I and IV, Grade 2, Classes B and C; BATIMIX Epoxy 100 Gel complies with ASTM C881 Types I and IV, Grade 3, Classes B and C.

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 100.

Mixing: Mix BATIMIX Epoxy 100 Gel using a low-speed drill and a mixing paddle. Do not thin BATIMIX Epoxy 100 Gel. Pre-mix Part A and Part B separately for about 1 minute each. Combine Part A and Part B in a 1 to 1 ratio by volume, and 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 100 Gel and mix thoroughly for 3 to 5 minutes. The mix ratio of aggregate to mixed epoxy is approximately 1 to 1 by volume, but can be modified depending on the desired consistency of the mortar. 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 (MV or Gel) apply BATIMIX Epoxy 100 Gel 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. Aggregate application rates will very depending on size and characteristics of aggregates used but will typically range from 3.5 to 5.0 kg/ m². Allow the epoxy to cure, then sweep and/or vacuum up the excess aggregate. Apply subsequent topping to the dried, sand-seeded epoxy.

To bond hardened concrete to hardened concrete (LV, MV or Gel) Apply BATIMIX Epoxy 100 Gel by spatula, brush, or trowel, ensuring the surfaces to be joined are uniformly coated and held firmly until the epoxy gels.

For anchoring bolts, dowels, pins (LV, MV or Gel), use BATIMIX Epoxy 100 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. Optimum hole size diameter is 1.6 mm to 3.2 mm larger diameter than anchor diameter). Depth of embedment is typically 10 to 15 times anchor diameter.

For patching and repairs (LV, MV or Gel), apply BATIMIX Epoxy 100 LV neat 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 100 Gel 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 (LV), upon ensuring no water is leaking from cracks, pump BATIMIX Epoxy 100 LV 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 (LV), by mechanical means ensure cracks are free of debris and water. If gravity feeding, pump BATIMIX Epoxy 100 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 (LV): Apply BATIMIX Epoxy 100 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 24 hours of prime coat application.

Cleaning: Clean tools, application equipment and spills immediately with acetone, xylene, or Methyl Ethyl Ketone (MEK) as once it hardens, removal of BATIMIX Epoxy 100 will need mechanical abrasion for removal.
