Best Practices for 3M 4200
-
Surface Preparation
There are waxes, coatings, sealants, grease, oil and other contaminants used in the marine industry, making it very important to clean all surfaces to be bonded before applying 3MTM Marine Adhesive/ Sealant 4200.
-
Application
Abrading the surface with a180 grit to 220 grit abrasive, will enhance the bond strength. Cut the plastic nozzle tip to the desired bead size. Puncture the seal in nozzle end of the cartridge and screw the plastic nozzle in place. Remove the bottom end seal of cartridge and place the cartridge in a caulk gun dispenser. Apply Fast Cure 4200 to the seam or part to be bonded. Position parts. Tool material to desired appearance. Tooling of adhesive can be accomplished by using a tongue depressor. If a finger is used, rubber gloves are recommended. Remove excess with General Purpose Adhesive Cleaner, P.N. 08984.
-
Clean-Up
For cleaning 3MTM Marine Adhesive/Sealant Fast Cure 4200 before it is cured, use a dry cloth to remove the majority of sealant, followed by a cloth damp with 3MTM General Purpose Adhesive Cleaner, P.N. 08984. Cured material can be removed mechanically with a knife, razor blade, piano wire or by sanding.
