VITREX® K MORTAR PHYSICAL PROPERTIES PROPERTY TEST TYPICAL DESCRIPTION AND USES METHOD VALUE VITREX K MORTAR is a potassium silicate corrosion Density ASTM C905 115 lb./cu. ft. resistant mortar which sets by chemical action. When (1.84 g./cc.) cured, VITREX K MORTAR exhibits outstanding Bond Strength, ASTM C321 150 psi. chemical resistance to dilute and high concentrations 7 days @ 77oF (25oC) (1.04 MPa) of oxidizing and non-oxidizing acids at temperatures Tensile Strength, ASTM C307 600 psi. o o to 1,700oF (927oC). Due to its excellent thermal and 7 days @ 77 F (25 C) (4.14 MPa) chemical resistance, VITREX K MORTAR is suitable Compressive Strength, ASTM C579 5,000 psi. 7 days @ 77oF (25oC) (34.5 MPa) for jointing acid resistant masonry sheathings in stacks, chimneys, ducts, absorbers, scrubbers and Flexural Strength, ASTM C580 1,800 psi. 7 days @ 77oF (25oC) (12.4 MPa) other high temperature process equipment. VITREX K Water Absorption ASTM C413 18% MORTAR complies with the specifications of ASTM C466 for chemically setting silicate and silica chemical Linear Shrinkage ASTM C531 2.8% resistant mortar. When mechanically mixing, the batch size should not CHEMICAL RESISTANCE exceed 30 lb. (13.6 kg.). When mixing by hand, use a When cured, VITREX K MORTAR is resistant to many shallow mixing pan (stainless steel, aluminum or organic and inorganic acids, salts and solvents. porcelain). Thoroughly mix only the amount of mortar Chemical resistant masonry sheathings jointed with that can be used in 20 minutes. The mortar cannot be VITREX K MORTAR provide excellent protection used after it begins to stiffen. Do not attempt to against aggressive corrosives, such as sulfuric, nitric retemper. Remove all material from the mixing and chromic acids at most concentrations. VITREX K container before another batch is mixed. When MORTAR is not recommended for use with alkalies, working at temperatures above 85oF (29oC), use small hydrofluoric acid or fluoride salts. batches no larger than 6 lb. (2.7 kg.). If the working life is still too short, cool the VITREX K Liquid before AVAILABLE COLORS using. When working at temperatures below 60oF VITREX K MORTAR is available in white only. (16oC), keep both the powder and the liquid in a warm storage area (75oF [24oC]) for 24 hours prior to use. PACKAGING Minimum air and substrate temperature for application VITREX K MORTAR is 50oF (10oC). 155 lb. (70.3 kg.) Unit Consisting of: One - 5-gal. pail of Liquid (50 lb. [22.7 kg.])* APPLICATION OF THE VITREX K MORTAR Two - bags of Powder (52 lb. 8 oz. [23.8 kg.]) ea. VITREX K MORTAR is buttered on chemical resistant brick using the Bricklayer’s method to achieve a *VITREX K Liquid is also available in a 550 lb. nominal 1/8" (3.2 mm.) joint thickness.

MIXING OF THE VITREX K MORTAR TYPICAL WORKING & SETTING TIMES OF THE VITREX K MORTAR is prepared by mixing 2.1 parts VITREX K MORTAR of VITREX K Powder to one part of VITREX K Liquid by weight. When preparing the mortar, it is Temperature Working Setting recommended that the liquid be placed in the mixing Time Time container and the powder added to the liquid. Mix 60oF (16oC) 60-90 min. 4-1/2 to 5-1/2 hours ratios may be varied slightly without harm to the 70oF (21oC) 30-40 min. 2-1/2 to 4 hours material to accommodate environmental conditions. 80oF (27oC) 15-25 min. 1-1/2 to 2-1/2 hours Mechanical mixing of the mortar is recommended 90oF (32oC) 5-10 min. 1 to 1-1/2 hours using a KOL or equivalent mixer.
