5.0 APPLICATION - GENERAL 5.1. Coatings shall be applied in accordance with the requirements of this specification guideline, to clean, dry surfaces during periods of favorable temperature and humidity conditions. 5.1.1. Surface temperature of the substrate should be at least 5°F above the dew point and rising, before any coating work is attempted. 5.1.2. No coating work shall be done at a relative humidity above 85%. 5.1.3. Coating application shall be restricted to ambient temperatures in the 55 to 90°F range. 5.1.4. Coating application shall be restricted to substrate temperatures in the 55 to 90°F range. 5.2. Surfaces to be coated shall have the specified surface preparation at the time of coating application. If surfaces have degraded or become contaminated subsequent to surface preparation and prior to coating, they shall be restored to the specified degree before coating application. 5.3. Stripe coat, using a brush, all welds, edges, corners, bolt heads, rivets. This operation shall be done before the application of the initial Futura-Bond 610HS coat. 5.4. Observe recommended recoat intervals between the initial application and subsequent overcoats. 6.0 PRIMER APPLICATION 6.1. Futura-Bond 610HS is a two component urethane primer that can be spray or roller applied over properly prepared metal surfaces at a dry film thickness of 2 - 4 mils and should be applied to all properly prepared surfaces. All Futura-Bond 610HS primed surfaces must be inspected prior to the application of Irathane 155. 6.2. Recommended application equipment: 30:1 ratio or larger airless spray unit with a minimum output of 2 ½ gallons per minute, Teflon packings and either nylon or Teflon lined material hoses. Spray tip sizes can range from 0.015 to 0.031inches. 6.2.1. Purge all lines and equipment with clean Xylene or Toluene thinner prior to and after spraying Irathane 155 to prevent a build up of material inside the spray unit and material hoses. Do not use Ketones, such as MEK, MIBK or Acetone. The use of Ketones will severely affect the cure of the Irathane 155. 6.3. Do not mix Futura-Bond 610HS until all surfaces are properly prepared and accepted for coating application. 6.4. Futura-Bond 610HS has a one and a half (1 1/2) hour pot life at 75°F, do not mix more material than can be applied in this period of time. 6.5. Futura-Bond 610HS may be thinned with acetone up to 15% by volume. N. Butyl Acetate may be added up to that allowable by local regulations. 6.6. Futura-Bond 610HS should not be applied in direct sunlight. 6.7. Refer to the current Futura-Bond 610HS Product Data Sheet for mixing and application instructions.

6.8. Futura-Bond 610HS shall be applied within eight (8) hours of the completion of abrasive blast cleaning and before any flash rusting occurs. 6.9. Futura-Bond 610HS has a minimum drying time of ten (10) hours and a maximum of twenty-four (24) hours, at 75°F for application of the Irabond UU 96. 6.9.1. If more than twenty-four (24) hours and less than forty-eight (48) hours drying time, at 75°F occurs with any Futura-Bond 610HS coat, an additional coat of Futura-Bond 610HS must be applied prior to the application of Irabond UU 96. 6.10. All of the above recoat times are temperature sensitive. Temperatures below 70°F will lengthen the recommended recoat times while temperatures above 70°F will shorten the recommended recoat times. 6.11. Uncured Futura-Bond 610HS shall be protected against damage from dust, detrimental foreign matter, and rain. 6.12. Before proceeding with the coating application it is necessary to generally inspect the substrate There must be no sharp corners and all edges should be rounded. Surface tension of the coating will cause reduced thickness in these locations and acceptable coating gauge may not be obtained. Acceptable rounded edges will be approximately 0.090 inches radius or larger. 7.0 ADHESIVE APPLICATION 7.1. Irabond UU96 should be used with Futura-Bond 610HS or if Irathane 155 recoat has exceeded as indicated in Section 8. 7.2. Irabond UU 96 is a one component adhesive system that can be spray or roller applied over Futura-Bond 610HS surfaces and should be applied at a 2-3 mil wet film thickness. 7.2.1. Power mix the Irabond UU 96 to a smooth uniform consistency. 7.2.2. Do not thin or cut Irabond UU 96. 7.3. Irabond UU 96 must be applied to the Futura-Bond 610HS within the recoat parameters indicated in Section 6.0. 7.4. The minimum recoat window for Irabond UU 96 is fifty (50) minutes and the maximum recoat window is five (5) hours at 75°F. TO AVOID ADDITIONAL WORK, DO NOT SURPASS THIS RECOAT WINDOW. 7.5. If the Irabond UU 96 recoat window is surpassed, by less than twenty-four (24) hours at 75°F, an additional coat of Irabond UU 96 must be applied. If it is more than twenty-four (24) hours, the surface must be abrasive blasted back to the original surface preparation requirements in accordance with Section 4.0 and primed with Futura-Bond 610HS.
