Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data is subject to reasonable deviation.
The Sauereisen Epoxy Matte Reinforced System No. 240 is a multiple layer, 1/8-inch thick, fiberglass reinforced lining for chemical-resistant construction of sumps, dikes, containment areas, trenches, walls, and floors. The Epoxy Matte Reinforced System offers superior resistance to most caustics, strong oxidizing solutions, and acids.
The basic system consists of separate Sauereisen materials including ConoWeld No. 501, Basecoat No. 240 and Saturant No. 241 combined with specified fiberglass matte which is purchased locally. Depending on service conditions, the system should be sealed with either ConoGlaze No. 202 or a second layer of Basecoat No. 240.
- Excellent resistance to splash and spillage of concentrated mineral acids, alkalies and some solvents.
- Maximum service temperature of 150°F (65°C).
- Superior tensile/flexural strengths.
- 100% solids material, no noxious or toxic odors during application.
- Low porosity.
Surfaces should be made free of oil, grease, water and other contaminants that may inhibit bond. This can be achieved by chemical cleaning.
Metal - Abrasive blast to a nominal 2.5-mil profile employing SSPC-SP10 Near White Metal Blast for immersion and SSPC-SP6 Commercial Blast for other service conditions. All welds must be continuous, free of flux and have a smooth rounded radius without any sharp edges.
Concrete - Concrete must be dry, firm, have attained 3000 psi compressive strength or be structurally sound as specified by the architect/engineer. Concrete should be floated free of ridges or depressions; all structural cracks must be repaired; voids filled, and slopes reestablished.
Abrasive blast or high-pressure water blast to remove laitance and obtain uniform sound substrate.
If chemical cleaning is utilized to remove contaminates, substrate must be neutralized. If abrasive- or high-pressure water blasting is used as the method of surface preparation, all sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner. If surface does not have desired profile, repeat surface preparation procedure.
With each component of the matte reinforced system, remix contents of Hardener Part A and Resin Part B components for a minimum of 2 minutes with a slow-speed paddle or "Jiffy" mixer. Add Hardener to Resin and mix for a minimum of 2 minutes until thoroughly blended. For Sauereisen Basecoat No. 240, mix Hardener/Resin combination for 2minutes and then gradually add Powder while mixing continuously for another 3 minutes.
Mix only complete batches. Material which has begun to set must be discarded. Do not try to retemper the material.
The Epoxy Matte Reinforced System is installed in 5 steps including the following... ConoWeld Primer, Basecoat, fiberglass reinforcement, Saturant, and a final topping of either ConoGlaze or Basecoat. Installation steps are as follows:
Apply ConoWeld Primer No. 501 by roller to a thickness of 5-10 mils using a short nap roller with a non-degradable core. For horizontal applications, installation of the basecoat of Basecoat may proceed immediately after placement of the Primer. For vertical applications, the Primer should be firm but tacky when the Basecoat is applied.
After mixing, trowel Basecoat No. 240 to 1/16" (approx. 70 ft2 per unit) over the Primer. This layer of the system will serve as the underlying body for the fiberglass reinforcement.
Immediately press woven fiberglass matte reinforcement into Basecoat No. 240. Apply fiberglass cloth in a uniform manner. Be careful not to wrinkle or intertwine material. Use 2" overlaps on the adjacent strips of cloth. Smooth matte reinforcement with a short nap mohair roller to eliminate air entrapment or pinholes.
Mix Epoxy Saturant No. 241 thoroughly and apply by brush, roller or spray until the fiberglass becomes translucent (approx. 100 ft2 per unit). Allow the installation to cure a minimum of 8 hours at 70°F before proceeding.
After Saturant No. 241 has cured, apply a sealing layer of ConoGlaze No. 202 at a thickness of 10 to 20 mils. The ConoGlaze may be applied by roller, spray or brush.
A skid-resistant surface may be attained by broadcasting silica sand into 10 mils of ConoGlaze. After a 12-hour cure, vacuum excess sand and seal with an additional 10 mils of ConoGlaze.
For areas subject to heavy loads and physical abuse, trowel a second 1/16-inch thickness of Basecoat No. 240 over the Saturant in lieu of the ConoGlaze topping. Finish with a short nap roller to eliminate voids and to remove trowel marks. Allow to cure at least 48 hours at 70°F prior to chemical exposure.
No. 501 200 ft2 per gallon at 8 mils.
No. 240 A unit will cover 70 ft2 at a thickness of 1/16-inch.
No. 241 100 ft2 per unit.
ConoGlaze (if specified)
No. 202 160 ft2 per gallon at 10 mils
*Coverages are theoretical and will vary depending upon surface conditions, porosity, application techniques and project specific conditions.
The Epoxy Matte Reinforced System will take an initial set in 18 hours at 70°F. Do not allow water or chemicals on the material surface for a minimum of 48 hours. For temperatures below 70°F, cure a minimum of 72 hours prior to water or chemical exposure.
ConoWeld Primer No. 501 is available in one-gallon and three-gallon kits.
Basecoat No. 240 is packaged in a unit that includes:
Hardener 1 half-gallon can
Liquid 1 gallon can
Powder 1 bag with 36.7 pounds
Saturant No. 241 is unitized as follows:
Hardener 1 half-gallon can
Liquid 1 gallon can
ConoGlaze No. 202 is available in one-gallon, three-gallon, and five-gallon units.
*Unitized packages are filled by weight, not volume. Container size does not indicate volume of contents. Fiberglass matte is to be purchased locally.
All equipment should be cleaned by scrubbing with a stiff brush and xylene or MEK at the end of each working period or when build-up becomes pronounced.
Sauereisen Epoxy Matte Reinforced System components have a shelf life of one (1) year when stored in unopened, tightly sealed containers in a dry location at 70oF. Avoid freezing. If there is doubt about the quality of the materials, consult a Sauereisen representative.
