A FRICTION REDUCTION SYSTEM FOR COATING PILES, DRILLED SHAFTS AND SHEET PILING PRIOR TO INSTALLATION IN ORDER TO REDUCE FRICTION IN CONSTRUCTION APPLICATIONS WHERE NEGATIVE SKIN FRICTION, DOWNDRAG FORCES, EASE OF INSTALLATION AND EXTRACTION ARE OF CONCERN.
ADVANTAGES
- Reduces peripheral anomaly activity in drilled shaft construction by creating an excellent plane between the drilled shaft casing and the cast-in-place concrete.
- Realize substantial friction reduction.
- Reduces uplift.
- Prolongs the life of piles, sheets and casings.
- Durable abrasion resistance.
- Save valuable time.
- Improved ease of installation, and an expeditious extraction process.
- Reduce maintenance costs.
- Reduce tidal friction on submerged piling.
- Better quality control of raw material selection when compared to that used in Bitumen coatings.
- More durable than Bitumen coatings
CONSTRUCTION BENEFITS
- More economical - fast curing allowing for more throughput per hour when compared to Bitumen coatings.
- Water-based coating, reducing the need for fire and HAZMAT protection associated with Bitumen coatings.
- Highly resistant to corrosion and chemicals common to construction.
- Surfaces stay clean reducing maintenance costs.
- Water-based, the environment is protected since toxins, chemicals, and harmful metals are not leached into the ecosystem as with bitumen coatings.
- Excellent bond breaking characteristics.
- Cleans up with water.
- Waterproof in a cured state.
- Stays in place even during hot weather conditions.
- Bonds to pile or casing.
- Provides excellent friction reduction between the earth and piling.
- Durable.
- Apply with conventional equipment.
- Replaces bitumen coatings which are unreliable, hazardous to work with, and difficult to maintain on the pile surface during driving, especially under high temperatures.

Water-base Slickcoat being applied to 65-foot piles.
Slickcoat cures at room temperature. Heat may be applied to speed up the curing process.
|
- Fast drying time for quick turn-around
- No sagging of the coating
- *No flash rusting
- The water-based coating allows for quick evaporation without the fear of fires
* Sandblasted, cold rolled steel should have a flash-rust additive applied to it if left in storage for any period of time before coating. The preferred flash-rust additive, Flash Shield Rust Inhibitor 104-K, can be supplied by Plastic Maritime or purchased from UltraChem LLC (phone 713-641-4245). If purchased from UltraChem, it should be cut 30:1 with water. It will delay flash rusting for 3 to 5 days. It is specifically formulated so that Slickcoat can be applied directly over it without loss of adhesion.

Type of Test:
Salt Fog Test
Tested for:
Kelly Hawkins, Hubbell Power Systems
210 N. Allen Street
Centralia, MO 65240
Applicable Standards: ASTM B117-2009
The numbers in parenthesis are instrument control numbers.
Refer to the record of performance for instrument details.
Equipment:
Autotech Salt Fog Chamber (5-3-048)
Environmental Laboratory
Procedure:
The pipe samples were placed in the Salt Fog chamber suspended on non-metallic
supports as shown in the photographs. Photographs of the samples were taken
initially, after 330.5 hrs, 542.2 hrs, 778.5 hrs, and at 1013.8 hrs.

Conclusion:
The best results were obtained from Samples F, G, and H, which were hot dip
galvanized before application of the Slick Coat. Samples C, D, and E performed nearly
well, except in the places where the Slick Coat had been damaged / chipped. Red rust appeared on the
outer diameter of the pipe where the coating had been removed. The different thickness of Slick Coat
did not appear to affect the corrosion resistance of any of the samples, black
or galvanized.
