    IF PLURAL COMPONENT EQUPIMENT IS REQUIRED STATE SO: Not required.

    (e) SPECIAL INSTRUCTIONS:

    PROVIDE INFORMATION FOR REPAIR PROCEDURES IF THE OVERCOAT WINDOW HAS BEEN EXCEEDED

    Refer to NAVSEA Standard Item 009-32 and applicable PPIs.

    Dry times are guidelines. Excessive film thickness, poor ventilation, and excessive humidity can cause deviation.

    *Antifouling must be applied before Amercoat 235 has cured hard. The film must be tack free, but still soft to fingertip pressure. ** For underwater hull applications, it is acceptable to launch based on the dry-time-to-launch of the antifouling.

    *Note that the final coat of Amercoat 235 should be tack free, but still impressionable with moderate fingertip pressure when applying the first coat of antifouling. This chart is presented as a guideline, but the coating should be inspected to ensure the dry state is

    sufficient for application of the antifouling according to these instructions.
