Preparation of the Substrate Coatings
Objectives: Students will
- prepare the substrates (surfaces) with various coatings for physical testing.
*** The teacher may choose to prepare the substrates the day before the classroom activities will be performed.
- Reynolds Heavy Duty aluminum (cut into 50 mm x 150 mm strips)
- Microscope glass slides
- Various coatings (including paints, epoxies, and waxes)
- Paint brushes
- Tongue depressors
- Newspapers and boxes for splatter control
- Follow manufacturer’s instructions on coating containers.
- Wear eye protection, lab coats or aprons, and gloves.
- Eye protection and gloves are extremely important in this activity, as paint tends to get everywhere.
- Preparations and paintings should be done in an adequately well-ventilated area.
- Obtain the necessary number of microscope slides and strips of aluminum as you will need.
- Thoroughly clean the slides with lab detergent and acetone prior to preparation.
- Label each slide and/or aluminum foils with identifying numbers and letters on the underside of the substrate you plan to coat.
- Apply a very thin and even coat on the selected number of substrates for each coating that you will be testing.
- Let dry thoroughly in an undisturbed area.
- Examine the substrates and coatings after the coating is completely dry.
