Application Procedure


Surface Preparation:

  • It is essential that all surfaces to be treated are properly prepared to obtain a strong bond between the substrate and the product as the metal putties only develop Physiochemical bonding with the substrate. Please refer SURFACE PREPARATION STANDARDS for more details.
  • The metal putties only develop Physiochemical bonding with the substrate. Please refer SURFACE PREPARATION STANDARDS for more details.
  • Thoroughly clean the surface with SavesPast ACR, Cleaner to remove all oil, grease and dirt.
  • Grit blast surface area with 8-40 mesh grit, although roughening using mechanical alternatives such as wire brush or abrasive disc can be used to leave a clean surface, free of scale, rust and other foreign substances., to create increased surface area for better adhesion to achieve desired profile is 50-80 microns.
  • Note for saline surface exposed metal surface: For metals exposed to sea water or other salt solution, grit-blast and high-pressure-water-blast the area, then leave Overnight to allow any salts in the metal to “sweat” to the surface. Repeat blasting to “sweat out” all soluble salts.Perform Chloride contamination test to determine soluble salt content (should be no more than 40pm).
  • Clean surface again with SavesPast ACR, Cleaner to remove all traces of oil, grease, dust or other foreign substances from the grit blasting.
  • Repair surface as soon as possible to eliminate any changes or surface contaminants/flash rusting/oxidation.

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:

    • Spread mixed material on repair area and work firmly into substrate to ensure maximum surface contact .Apply a very thin scratch or smear coat directly to the prepared surface to maximize surface contact before proceeding to apply additional product to the desired build.
    • Ensure product has been worked into all cracks and voids to eliminate air bubbles. If applying several coats or layers, any previouslyapplied product must be roughened if it has been left to cure for more than 24hours.
    • Do not "feather-edge” epoxy.
    • 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.

        TEMPERATURE 5°C (41°F) 10°C (50°F) 15°C (59°F) 20°C (68°F) 25°C(77°F) 30°C (86°F)
        Movement or use involving no loading or immersion 4 hrs 3 hrs 21/4hrs 1 3/4 hrs 1 hr 3/4 hr
        Machining and/or light loading 6 hrs 4 hrs 3 hrs 2 hrs 1 1/2 hrs 1 hr
        Full electrical, mechanical or thermal loading 4 days 2 days 1 1/2 day 1 day 20 hrs 16 hrs
        Immersion in chemicals 5 days 4 days 3 days 2 days 1 1/2 days 1 day
       
      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
