Application: 810 may be used directly from the dual  cartridge unit or plural component pump.  Mixing of the product  is through a static mixer. 

Surface Preparation: Surface is to be free of all contaminants that would act as a bond breaker.  The area to be sealed should be sound to the degree that good bonding of the product will result when properly applied.  The area should be dry.

Curing Time: Back in service time –traffic-  1 to 1.5 hours approximately. Re-coat 30 minutes to 45 minutes @ 70°F.  Full cure in 6 to 8 hours @ 70°F.  

Concrete: Must be cured at least 28 days. All surfaces must be dry and dust free.

Shelf Life: Six Months, store between 70°F and 90°F.

Packaging: 21 and 54 ounce duplex cartridge kits, 10 gallon kits (5 gallon pails) and 110 gallon kits (55 gallons per drum).

VOC Content: 0gms/1 or 0.0 lbs/gal

Limitations: Do use on wet surfaces or expose part A to moisture.  Keep out of direct sunlight, store at room temperature. Do not allow the product to stand in the static mixer.  Use at 5 degrees F above dew point. Keep cartridges warm when using product in cool conditions.

⚠️ Do not expose boxes of cartridges to sunlight or store in hot areas as this will accelerate gel time.  Important:  Hot conditions will speed the set time of the product, while cool conditions will slow the set time.

Modular Fiberglass Tank Bonding

• Fiberglass Sumps – modular tank sections bonded in the field with Madison’s 810 series product.

• 810 – slow system, duplex cartridges, high chemical resistance applied using a pneumatic duplex gun. Set time approximately 5 to 8 minutes.

1. Surface Preparation

• Clean & Dry: Ensure the substrate is completely dry and free of dust, dirt, oil, or any contaminants that act as a bond breaker.

• Concrete Prep: Concrete must be fully cured for at least 28 days before application.

• Fiberglass/Tank Channels: Clean the channel thoroughly and abrade (sand) the surface as needed to ensure an optimal mechanical bond.

2. Dispensing & Application

• Setup: Apply directly from a duplex cartridge unit (using a manual or pneumatic gun) or a plural component pump through a static mixer.

• Execution: Apply the mixed material smoothly into the joint or repair zone. If bonding tank perimeters, move quickly and continuously around the perimeter.

• Note: Do not allow product to stand still in the static mixer to prevent premature clogging.

3. Curing & Return-to-Service

• Touch-Dry / Re-coat: 30 to 45 minutes at 70°F.

• Light Traffic / Back in Service: Approximately 1 to 1.5 hours.

• Full Cure: 6 to 8 hours at 70°F.

Advantages

• Vertical hold directly from the cartridge or static mixer

• Can be sprayed over with polyurea

• High chemical resistance, fuel resistant.

• Highly adhesive to many substrates

• Fast set, trowel-able

• Bonds to plastic, urethane, polyurea, fiberglass, steel, wood and concrete

• Cartridge dispensed

• Can be sanded and painted quickly

Use Areas

• Rapid “bug-hole” filler for polyurea spray applications or floor applications

• Plastic repairs

⚠️ Speed is temperature dependent Sanding Time depends on set time of product.  Faster set provides faster sand time.  Hot conditions speed the set time, cool conditions slow the set time.

Various Set Times: 820 is designed to set with several gel/set time speeds:  820-45/60 is 45 to 60 seconds gel time, 820-60/120 seconds, 820-240/360.  The product set time is temperature dependent, i.e., warm or hot conditions will speed the set time and cool conditions will slow the set time.

Color:  The product is black or non-pigmented having a whitish color when mixed properly and after it has set.  820 has no odor and is 100% solids.

Application: The product is mixed and applied via a 1:1 duplex cartridge or a plural component 1:1 ratio pump fitted with the proper static mixer.

Surface Preparation: Surface is to be free of all contaminants that would act as a bond breaker.  The area to be sealed should be sound to the degree that good bonding of the sealer will result when properly applied.  The area should be dry.

Plastics:  Abrade as needed, solvent wipe and prime.  Consult Madison for various substrate primers.

Concrete:  Must be cured at least 28 days. All surfaces must be dry and dust free.

Limitations:  Do use on wet surfaces or expose part A to moisture.  Keep out of direct sunlight, store at room temperature. Always shake the part B before using.  Do not allow the product to stand in the static mixer.  Use at 5 degrees F above dew point. Keep cartridges warm when using product in cool conditions.

Shelf Life:  Six months; store between 40°F and 100°F.

Finish:  This product has a High Gloss finish and can be sanded and painted as needed.

Pot Life:  No potlife, dispensed from pumps or cartridges. 

Curing Time:  Depends on set time of the product. Recoat 2-8 hours @ 70°F.  Full cure in 24 to 48 @ 70°F.   This product is for use by professional applicators only. Wear Protective Clothing. Read MSDS before using this product. DOT/Flash Point – Non-flammable Liquid Classification, not regulated.

1. Surface Preparation

• Clean & Dry: Ensure the substrate is completely dry and free of dust, dirt, oil, or any contaminants that act as a bond breaker.

• Plastics: Abrade the surface as needed, execute a solvent wipe, and prime (consult manufacturer for substrate-specific primers).

• Concrete Prep: Concrete must be fully cured for at least 28 days and be completely dust-free before application.

2. Dispensing & Application

• Setup: Always shake the Part B component thoroughly before use. Apply directly from a 1:1 duplex cartridge unit (using a manual or pneumatic gun) or a 1:1 ratio plural component pump through a proper static mixer.

• Execution: Apply the mixed material smoothly into the joint, crack, or vertical profile. Trowel and move the thixotropic gel as needed for structural filling.

• Note: Do not allow product to stand still in the static mixer to prevent immediate curing and clogging.

3. Curing & Return-to-Service

• Touch-Dry / Re-coat: 2 to 8 hours at 70°F (highly dependent on the specific speed grade selected).

• Sanding Window: Highly dependent on product set time; faster speed formulations allow for a significantly accelerated sand-and-paint window.

• Full Cure: 24 to 48 hours at 70°F.
