Description

Armor Plate 991 is a pourable grade epoxy grout that is ideal for a variety of maintenance and construction projects. AP 991 is so versatile because it forms an impervious chemical and moisture barrier that inhibits corrosive and oxidizing processes at the rebar and anchor bolts.

AP 991 is primarily used for grouting rebar and anchor bolts. It is also used as a patching compound for concrete, steel, and wood. AP 991 will also bond new concrete to old concrete.

AP 991 is recommended to anchor equipment such as compressors, diesel engines, printing presses, power generators, hydraulic presses, turbines and pumps.

Advantages

  • Exhibits outstanding strength properties
  • Resists a wide variety of chemicals
  • Quick and easy to install
  • Can be applied in damp or dry conditions.
  • Demonstrates strong bonding characteristics

Chemical Resistance

Armor Plate 991 forms a chemical barrier that is resistant to a wide variety of chemicals, including caustics, dilute acids, salt solutions, water, steam and petroleum solvents. Contact the Wil-Cor, Inc. Technical Department for chemical resistance in specific service conditions.

Physical Properties

Color (mixed) Gray
Mixing Ratio (by vol.) Resin (pt A) : Cure (pt B) 1 : 1
Flashpoint (C.O.C.)
Resin (part A) 210 °F
Cure (part B) 180 °F
Operating Temperature Range
Continuous High 200 °F

Barcol Hardness (Scale E) 80

Mixing

Mix Armor Plate 991 Resin (part A) and Cure (part B) in equal proportions, by volume. Stir the mixture for at least 2 minutes, until a homogenous mixture is obtained. After the grout material is blended, clean, dry sand may be added.

Application

Armor Plate 991 may be applied with a brush. When placing AP 991 in anchor bolt or rebar holes, pour the hole one-quarter full and insert bolt. This method will assure that the anchor bolt or rebar is completely surrounded by the grouting material.

Packaging

Armor Plate 991 is available in stock sizes of 2-quart, 2-gallon and 10-gallon units.

Coverage and Estimating

The theoretical coverage of the Armor Plate 991 is:

Without Aggregate 231 cu. in./gal.
With Aggregate (3:1 ratio) 924 cu. in./gal.

The amount of grout (with aggregate) needed, without consideration of losses during mixing and application, is determined from the following formula:

G is the Amount of Grouting Material needed (gallons)
r1 is the Radius of the Holes to be filled (inches)
r2 is the Radius of the Bolt or Rebar (inches)
d is the Depth of the Hole (inches)
n is the Number of Holes to be filled

The amount of AP 991 needed, in gallons, is:

G / 4 ( 1 gal. / 231 cu. in.)

Shelf Life

The shelf life of AP 991 is a minimum of one (1) year if kept in tightly sealed containers in a dry location. AP 991 may keep up to 4 to 5 years. After one year of shelf life it is recommended that a test batch be mixed to determine its reactivity. Freezing or temperatures in excess of 110 °F will not affect the shelf life of AP 991

0.50 0.20 2.50 4.90

2.00 3.15 4.00 12.55
Example
1″ dowel in a 1.5″ hole that is 12″ deep
How much grout is needed?
From the chart above:
1″ dia. dowel: 0.80 sq. in.
1.5″ dia. hole: 1.75 sq. in.
Void area (area to be filled with grout):
(1.75-0.80) sq. in. = 0.95 sq. in of void area.
0.95 sq. in. X 12 in. = 11.4 cu. in. of grout needed.
Miscellaneous Data
1 gal. = 231 cu. in. 1 gal. = 144 sq. in.
1 gal. = 128 fl. oz. 1 sq. yd. = 9 sq. ft.
7.5 gal. = 1 cu. ft. 1 mil = .001 in.
1 cu. ft. = 1728 cu. in. 100 lbs. sand = approx. 7 gal.
