1. Using a PDS
Use this guideline to properly review a PDS:
! WARNING – Review SDS and PDS prior to starting coating work.
! WARNING – Review SDS for Personal Protective Equipment (PPE) requirements.
| Step | Action |
| 1.1 | Obtain the most current copy of the SDS and PDS for the product. |
| 1.2 | Review the SDS for information relating to occupational safety and health for the chemicals in use. |
| 1.3 | Obtain the PDS from supervision, Mandros office, online, or from product supplier.
◆ Caution: Reviewing the PDS is critical to proper mixing and application of the material, and not following the PDS can cause coating failures. |
| 1.4 | Review the Product Description, Performance Characteristics, and Recommended Uses to ensure that the product is a good fit for the application. |
| 1.5 | Review the Product Characteristics
• Volume of Solids: to understand at what thickness the coating should be applied (wet mils) and how that relates to cured/ dried coating thickness (dry mils). • Mixing ratios: to understand what proportions the components must be mixed at for the system to perform properly. • Recommended coverage rates: to understand how much material is needed for the amount of surface area that requires coating. • Drying schedule: to understand: o When it is safe to touch o When it is safe to handle o How long until you can recoat as well as the length of time available to apply additional coatings before additional surface prep is needed. o Time until it is fully cured • Shelf life and pot life: to understand o How long the product is good for after its manufactured date. o How long you have to work with the product once it’s mixed. • Sweat-in Time: when applicable, to understand the amount of time to wait after material is mixed until it can be used. • Flash point: to understand the lowest temperature at which vapors of the material will ignite • Proper solvents to use for thinning and cleanup |
| 1.6 | Review Recommended Systems section to verify compatibility of coating with various primers, intermediate coats, or top coats on different substrates. |
| 1.7 | Review Surface Preparation section to determine how substrate should be prepared prior to coating application. |
| 1.8 | Review Application Conditions to ensure that coating materials are applied within the environmental parameters.
• Air temperature • Material temperature • Surface temperature • Relative humidity • Dew point |
| 1.9 | Review Ordering Information and verify proper container sizes and quantities are onsite before mixing. |
2. Using an Application Data Sheet or Application Bulletin
Use this guideline to properly review an ADS.
| Step | Action |
| 2.1 | Much of the information in the ADS is the same as the PDS. If you need more detail on the product characteristics, review the ADS information more thoroughly. |
| 2.2 | Application Procedures: This section describes how the material should be mixed and applied. |
| 2.3 | Application Equipment: This section describes the proper equipment and equipment specifications needed to apply the material correctly. |
| 2.4 | Performance Tips: This section describes techniques to most effectively apply the material. |
