Amercoat 182 Spec Sheet.pdf

Product Data/ Application Instructions

• Formulated for application and cure underwater in fresh or salt water

• 100% solids epoxy

• Excellent cathodic disbondment resistance

• Excellent water resistance

• Effective corrosion barrier

• Excellent chemical and solvent resistance

Tideguard 182 is a special polyamide epoxy mastic for use on those areas of marine structures and pipelines which cannot be maintained effectively with conventional coatings or cathodic protection.

Many years of service around the world confirm the effec-tiveness of Tideguard 182 as a corrosion barrier.

Typical Uses

• Repair underwater pipe

• Repair underwater pilings and bracings

• Repair water line structures and retaining walls

Typical Properties – after 7 days @ 70°F (21°C)

Mechanical Density (ASTM D71 modified) 100 lbs/ft3

Hardness (ASTM D3363) 6H

Application Data Summary Adhere to all instructions, precautions, conditions and limitations during storage, handling, application and drying periods to obtain maximum performance. For conditions outside the requirements or limitations described, contact your PPG representative.

Surface Preparation Coating performance, in general, is proportional to the degree of surface preparation.

Steel – Surfaces should be abrasive blasted to remove rust, scale, old coating and barnacles. Abrasive blasting can be done with conventional equipment below the water as well as above.

Wet abrasive blasting and power tool cleaning can be used as long as a deep profile is created, and old rust scale is removed.

Below 65°F (18°C) workability is reduced and application more difficult. Above 80°F (27°C) working time decreases.

Tideguard 182 can be applied to surfaces as low as 50°F (10°C);

although curing is slower at lower temperatures, typical properties of cured material will not be affected.

Mixing Tideguard 182 coating is supplied as two components. Mix both components together until a uniform gray color is obtained with no streaks. Avoid over-mixing after the gray color is achieved as over-mixing will shorten the pot live.

Note: For in-water applications, consult applicable regulations concerning safety precautions and equipment.

Application Tideguard 182 coating may be applied by hand smearing to a thickness of 1⁄8 to 1⁄4 inch for long-term protection. Best results in manual application can be obtained by applying a ring or doughnut of the material to structural members above the water level and then smearing it down uniformly to, and below, the water level, making an effort to feather edge the top and bottom to the member. The applicator’s hands should kept wet at all times so that the material can be molded like putty to the structure. A little more effort is needed to keep the material in place as it is applied below the water level; this calls for patience in holding and working the product.

An alternate method of application to tubular members consists of carrying the product on to the surface with a membrane such as fiberglass cloth or canvas ducking. This method is preferred where wave action and/or currents make hand smearing impractical. The membrane should be cut in strips 2 inches longer than the pipe circum-ference. Hand smear the mixed coating to the membrane, wrap, and tie to the surface. The coated side of the membrane should be pressed carefully against the surface to displace water. When coating small diameter pipes, it is recommended that 4 or 6 inch fiberglass tape be used as the membrane. After coating, this can be spiralled on and tied to the surface.

It is sometimes helpful and desirable, especially in rough water, to apply a spiral wrap of polyethylene, glass fiber, burlap, cheesecloth, or other similar material over the freshly applied coating to help hold the coating in place during the initial curing operation.

To achieve the optimum thickness of 1⁄8 to 1⁄4 inch, the coverage per gallon should not exceed 6 to 12 square feet. A two-person crew can apply one gallon of mixed material in approximately 30 minutes.

Tideguard 182 coating is 100% solids and contains no flammable solvents.

Cleanup Clean all mixing equipment and application tools immediately with Amercoat 12 or T-10.

Safety Precautions Read each component’s material safety data sheet before use. Mixed material has hazards of each component. Safety precautions must be strictly followed during storage, handling and use.

CAUTION – Improper use and handling of this product can be hazardous to health.

Do not use this product without first taking all appropriate safety measures to prevent property damage and injuries. These measures may include, without limitation: implementation of proper ventilation, use of proper lamps, wearing of proper protective clothing and masks, tenting and proper separation of application areas. Consult your supervisor. Proper ventilation and protective measures must be provided during application and drying to keep spray mists and vapor concentrations within safe limits and to protect against toxic hazards. Necessary safety equipment must be used and ventilation requirements carefully observed, especially in confined or enclosed spaces, such as tank interiors and buildings.

This product is to be used by those knowledgeable about proper application methods. PPG makes no recommendation about the types of safety measures that may need to be adopted because these depend on application environment and space, of which PPG is unaware and over which it has no control.

If you do not fully understand these warnings and instructions or if you cannot strictly comply with them, do not use the product.

Note: Consult Code of Federal Regulations Title 29, Labor, parts 1910 and 1915 concerning occupational safety and health standards and regulations, as well as any other applicable federal, state and local regulations on safe practices in coating operations.

This product is for professional use only. Not for residential use.
