SEALING WITH THERMAL-CURE SEALANTS
Tools and Equipment Required:
•
Foam brush or applicator
•
Thermal Cure sealant
•
Convection Oven capable of at least 100°C
•
Vacuum Chamber (optional)
Procedure
1. Place the clean part on a tray to catch excess sealant.
2. Apply the sealant to one side of the part using the foam brush. Be sure the entire side is coated.
3. After the part face is coated, let the sealant sit on the part for 5 to 10 minutes to saturate the part surface.
4. Turn the part over and apply sealant to the back side of the part.
5. Set the oven to 100°C. Remove any excess sealant and place the part in the oven for 1 to 1.5 hours or longer for parts with
thick cross-sections.
6. Remove the part and apply a second coat of sealant, repeating steps 2 through 5.
3. Remove the part from the sealant and shake off the excess.
4. Use compressed air to blow excess sealant off of inside features and out of cavities.
•
Air dry the part for 4 to 24 hours, depending on part density and size. You can speed drying by using an oven at low
heat (50°C).
