Description

Armor Plate 999 is a high strength, thermosetting, epoxy grout system. AP 999 is a packaged, premeasured, three-component system of epoxy resin, epoxy catalyst, and inert aggregate. This laboratory tested mixture produces a foundation grout with homogenous aggregate distribution. The rapid high strength and chemical resistance of the AP 999 grout provides an equipment foundation which is long-lasting, economical and maintenance free.

Because of its quick cure time, AP 999 is excellent for areas where equipment must be placed in service with a short downtime. It has been used to grout all the equipment at the Prudhoe Bay, Alaska, North Slope Operations. AP 999 is used to pace equipment such as compressors, pumps, centrifuges, turbines, generators, kilns, steam engines diesel engines, milling machines, blowers and presses.

Advantages

  • Short cure time – Can be placed in service quickly
  • No surface bubbling – Uniform, high strength surface with more than 95% bearing area
  • Easy mixing – Premeasured, color-coded components
  • Can be placed at temperatures as low as 45 °F
  • High, non-volatile flashpoint – Can be shipped by air
  • Used for grouting at Prudhoe Bay, Alaska

Chemical Resistance

Armor Plate 999 is resistant to strong caustics, mild acids, oils, grease, water, steam, salts and solvents.

Mixing

Armor Plate 999 is packaged as a three-part, premeasured system of Resin (A), Cure (B), and Aggregate (C).

Resin and cure must be thoroughly mixed before aggregate is added. DO NOT add aggregate before resin and cure are properly mixed

Mix the AP 999MP according to the following instructions:

  • 1Add Armor Plate 999MP Cure (part B) to Armor Plate 999MP Resin (part A). DO NOT add Aggregate at this time.
  • 2Mix Resin and Cure thoroughly for at least 2 minutes. Use an electric mixing blade, a horizontal agitator, or other mechanical equipment suited for producing homogenous mix.
  • 3Pour the completely mixed AP 999MP Resin and Cure into a concrete or mortar mixer.
  • 4Add one-half of the AP 999MP Aggregate (part C) and mix until it is thoroughly wetted.
  • 5Add the remainder of the Aggregate and mix until all of the aggregate is thoroughly wetted.
  • 6For smaller batches use a 3/4″ drill and mix one (1) gallon with 50 lbs of Aggregate (part C).

Surface Preparation

  • 1A clean surface is necessary. Remove dirt, oil and other contaminants from old concrete surfaces. Remove laitance from all new concrete. The surface can be cleaned by detergent washing, acid etching, sandblasting, or other mechanical means.
  • 2Metal surfaces should be cleaned of any rust or scale by sandblasting or other mechanical means.
  • 3All application surfaces must be dry.
  • 4Wax construction forms to prevent bonding of the AP 999. They should also be liquid-tight and strong enough to support the weight of the AP 999.
  • 5Wax any other surfaces that are not to be bonded to the AP 999.
  • 6Remove all oil-contaminated concrete.

Packaging

Armor Plate 999 is a three-component system available in the following units:

Unit Size 1.2 cu. ft. 2 cu. ft.
Net Weight 61.04 lbs 244.16 lbs
Resin (part A) 10.00 lbs 40.00 lbs
Cure (part B) 1.04 lbs 4.16 lbs
Aggregate (part C) 50.00 lbs 200.00 lbs

When estimating the amount of AP 999 needed for the job, consider the loss of material when mixing and placing the grout.

Application

To achieve the best results, Armor Plate 999 should be kept at about 70 °F prior to application.

Armor Plate 999 is poured to a depth of between 1.5 and 4 inches. The maximum depth of a pour in large areas should not exceed 4 in., unless reinforcing is used. Pours deeper than 4 in. may be made in small areas only. Use rebar steel or clean rocks as a heat sink in deep areas.

Consecutive pours (maximum 4 in.) may be made without reinforcing after each previous layer has cured and its heat has dissipated. Previous pours should be sanded or chipped before the next pour is made.

Provide expansion joints every for (4) to five (5) feet.

Armor Plate 999 may be pumped when grouting wide, shallow areas. For pumping information Contact Wil-Cor, Inc. for equipment rental rates and supervision.

Armor Clean, MEK, Methylene Chloride or gun cleaner may be used to clean equipment.

The table below gives an estimate of the working and cure times of AP 999 at various temperatures. The times are approximations and will vary with humidity and desired service conditions.
