Application Procedure


Surface Preparation:

  • For sealing of active and live fluid and oil leakages:
  • Remove all dirt, barnacles, flaking paint, and algae/seaweed from the substrate.
  • Wipe area with a clean cloth to remove any film on the surface. Obviously you cannot degrease the fluid/oil, but wiping and turning a clean cloth often will remove any film on the surface.
  • Abrade the surface if possible. (Use mechanical means or a file to accomplish.)
  • The oxidation can be removed by mechanical means, such as water, grit-blasting, or by chemical means.
  • Make the repair as soon as possible to avoid surface contamination.

Technical tips for working with epoxies

  • Working time and cure time depends on temperature and mass:
    1. The higher the temperature, the faster the cure.
    2. The larger the mass of material mixed, the faster the cure due to exothermal reaction.
  • To speed the cure of epoxies at low temperatures:
    1. Store epoxy at room temperature.
    2. Pre-heat repair surface until warm to the touch.
  • To slow the cure of epoxies at high temperatures:
    1. Mix epoxy in small masses to prevent rapid curing.
    2. Cool resin/hardener components.

Mixing Instructions:

  • It is strongly recommended that full units be mixed, as ratios are pre-measured.
    1. Add hardener to resin.
    2. Mix thoroughly with screwdriver or similar tool while continuously scrape material away from sides and bottom of container until a uniform, streak-free consistency is obtained.
  • For smaller volumes
    1. place resin and hardener on a flat, disposable surface such as MonKit or plastic sheet. Use a Spatula or trowel/ wide-blade tool to mix the material.
  • For larger volumes
    1. Use a T-shaped mixing paddle or a propeller-type Jiffy Mixer Model ES on an electric drill. Thoroughly fold putty by vigorously moving paddle/propeller up and down until a homogenous mix of resin and hardener is attained. Thoroughly mix the components for at least 4 minutes to get uniform mixture.
    2. Avoid the formation of bubbles. Do not mix more than you are able to use within the pot life. If the container is partly used, it is to be kept tightly closed.

Application Instructions:

    • Insert a machine screw/cork where applicable to slow the leak pressure
    • When applying to a leaky surface, it is important that the Zero-Down-Time ETP be applied with sufficient pressure to force fluid/oil away from the interface between the adhesive and substrate.
    • Application by trowel or putty knife is normally sufficient to ensure this fluid/oil displacement.
    • Underneath patching can also be usefully carried out by preparing a 'poultice' on a piece of plastic sheet and placing this under hand pressure against the area being treated.
    • Ascertain the stoppage of leak
    • The plastic can be peeled away later, if desired.
    • Application to dry or damp surfaces can be achieved satisfactorily with trowel or putty knife.
    • Fiberglass cloth, SavesPast ART can be used to strengthen the patch or assist in bridging gaps or cracks.
    • Encapsulate using SavesPast SP, Steel Putty to reinforce the leakage repair and makes it permanently leak proof.
    • FOR BRIDGING LARGE GAPS OR HOLES
      1. Place fiberglass sheet, expanded metal, or mechanical fasteners between repair area and SavesPast TP prior to application.
    • FOR VERTICAL SURFACE APPLICATIONS
      1. SavesPast TP can be troweled up to ½” thick without sagging. Chemical immersion is possible after 24 hours.
    • FOR MAXIMUM IMPROVEMENT OF PHYSICAL & CHEMICAL PROPERTIES
      1. Cure at room temperature for 2.5 hours, then heat cure/elevated temperature for 4 hours @ 90°C.

    Smoothening

    If a smooth surface is desired, there are two possible ways to accomplish it.

    • For small or curved areas, apply a small amount of isopropanol alcohol or acetone to the top of the epoxy compound and smooth using either a gloved hand or trowel, as the solvent prevents sticking. The usage of water may produce a white film on the finished surface and do not mix the solvent into the epoxy.
    • For large or flat areas, a sheet of non-stick Polyethylene or Polypropylene can be applied to the surface. Once the material has been cured, it can be pulled off, leaving a smooth surface.

    Note: Reduction of the coating thickness is much easier when the coating is applied than after the very hard and abrasive resistant coating is cured

    Cure:

    • Variations in cure may arise due to the amount of material being applied, the thickness of material being applied, the surface temperature, and the product temperature. The cure may be increased by applying external heat to the prepared surface before application of the product. This can be done with heat lamps, hot air gun, ELECTRIC BLANKET or other heat sources. Do not use open flame. The cure may be decreased by cooling the product before mixing.

      Rule of thumb: Every increase of 10° C above room temperature leads to a reduction of pot life and cure time by 50%

    Machining:

    • Allow material to cure for at least four hours before machining, but wait no longer than 24 hours as the material will wear the tools. Machine using these guidelines:
      1. Lathe speed: 150 ft./min
      2. Cut: Dry
      3. Tools: Carbide Top Rake 6° (+/-2°) – Side/Front 8°F (+/-2°)
      4. Feed Rate (rough): Travel speed .020 Rough cut .020 - .060
      5. Feed Rate (finishing): Travel speed .010 Finish cut .010
      6. Polishing: Use 400-650 grit emery paper wet. Material should polish to a 25-50 micro inch.

    Chemical Resistance:

      • Chemical resistance is calculated with a 7 day, room temp. cure (30 days immersion) @ 25°C)
      • Please Refer the table : Clik Here

    SHELF LIFE

    • Store away from heat and direct sunlight. A minimum of 3 years should be expected if held in original unopened containers

    Product Limitation:
