One of the most important aspects of a successful coating application is the ability of the applicator to successfully transfer the coating from the container to the surface. This guide has been prepared to assist the applicator in achieving that goal.
SUBSTRATE AND SURFACE PREPARATION
Proper surface preparation is paramount to the successful application of an industrial coating. The better the surface preparation, the better and longer lasting the performance of the coating.
Remove all oil, grease, dirt, soil, salts and contaminants from the surface to be coated.
Soluble salts and emulsifiable contaminants are best removed with pressurized water and specialized detergents.
Steel surfaces should be prepared to SSPC-SP 2 or SSPC-SP 3
Any remaining abrasive media must be removed from the surface. Coating performance will be compromised if applied over any residual media. A thorough vacuuming of the abraded surface is recommended.
If used over lead or asbestos materials all applicable state and federal regulations for proper surface preparation and encapsulation must be followed
IAG Multi-Functional: Conventional airless equipment 30:1 min pump ratio generating minimum operating pressure of 3000 p.s.i. .013 -.030 Tip Size 20° to 40° Fan Angle depending on section being sprayed
IAG Fire Retardant: 3500 - 4000 p.s.i. .037 tip with 4" to 6" fan conventional airless 68:1 or 74:1 pump with ram platie.
Brush or roller
Proper mixing is critical for achieving a consistent and uniform coating.
Any unmixed resin or hardener will not cure properly! Only adequate mixing will result in a successful coating.
AMP is a two-part system. Pour entire contents of Hardener part B into the Resin part A container. Mix with a ½" drill equipped with an industrial paddle. Mix at medium speed. Scrape the sides and bottom of the container and fold coating into itself and continue to mix until a homogenous mixture is obtained.
For best results, transfer entire contents into a clean container scraping bottom and sides of original container and repeat above mixing procedure.
Airless Spray: A single coat built up with a number of quick passes allows greater control over quantities, thickness and finish. In certain conditions it may be advantageous to apply multiple thin coats rather than one thick coat. However, it is necessary to ensure that the first coat is dry before applying additional coats
For brush application, a fully loaded brush should be used. A laying on stroke should be used.
A short- nap or foam roller may be used.
Application rates at an ambient temperature of 70°F Airless Spray 60 mils WFT Brush/Roller 14 mils WFT
Surface temperature should be a minimum of 5°F above dew point. Protect uncured AMP coating from moisture, rain or running water until the coating is completely dry.
AMP has a theoretical pot life of 60 minutes @ ambient temperatures (25°C/50RH).
During application, wet film thickness should be checked with a wet film gauge. Insert the teeth into the wet coating. The last tooth coated indicates the thickness achieved. Recommend minimum of 25 mil thickness.
AMP contains no solvents and does not exhibit any appreciable shrinkage. WFT should be equal to DFT.
Drying times are dependent upon a number of factors.
Thickness of AMP
Method of application
Anticipate a full cure time of 48 hours at 25°C.
AMP can be over coated with itself as soon as the previous coat has dried. Based on airless spray application at ambient temperature and 50% humidity, 18 hours is the recommended time before over coating.
Pump, mixer and hose should be cleaned according to the equipment manufacturers specifications. AMP can be cleaned with conventional solvents such as acetone or isopropyl alcohol.
STORAGE, HANDLING & SAFETY
AMP, like most epoxy compounds, possesses the ability to cause skin and eye irratation upon contact. Certain individuals may also develop an allergic reaction after exposure (skin contact, inhalation or vapors, etc.) which may manifest itself in a number of ways including skin rashes and an itching sensation. Handling this product at elevated temperatures may also generate vapors irritating to the respiratory system. Always read material safety data sheets before using these or any other chemicals.
Store product in a dry and clean environment in original unopened containers. Recommended storage temperature is between 50° and 80°F.
