3M 200 mL Controlled-Flow Seam Sealer (8329)

3M 200 mL Controlled-Flow Seam Sealer (8329) is a two-part urethane-based sealant specifically designed for automotive applications. It offers precise application and a controlled flow rate, making it ideal for sealing joints on sloped surfaces where excessive material flow can be a concern.KEY FEATURES AND BENEFITS: Controlled Flow: Limits material flow to 1-2 inches on non-level surfaces, preventing waste and ensuring consistent film thickness. Fast Curing: Cures completely in 2 hours and is ready for painting in approximately 40 minutes, allowing for efficient workflow. Excellent Adhesion: Adheres well to properly prepared surfaces such as 2K urethane, 2K epoxy primer, and clean, sanded paint. Durability: Withstands torsional stress, vibration, and extreme weather conditions. Flexibility: Resists cracking and shrinking, ensuring long-lasting performance. Self-Leveling: Creates a smooth, even finish for a professional appearance.SPECIFICATIONS: Color: Black Work Time: 3 minutes Cure Time: 2 hours Paint Time: 40 minutes Size: 200 mL cartridgeHOW TO USE: Surface Preparation: Scuff the primed surface using a Scotch-Brite General Purpose Hand Pad (Ultrafine). Remove dust and debris using clean, compressed air and a dry cloth. Product Preparation: Insert the cartridge into the applicator gun. Remove the retaining collar and plug. Extrude a small amount of material to ensure proper mixing of both parts. Attach the 3M Mixing Nozzle and lock into place with the retaining collar. Discard the initial mixed material. Application: Apply the sealer evenly to the prepared surface. Allow the sealer to cure for a minimum of 40 minutes before proceeding with painting. If curing exceeds 24 hours, lightly scuff the sealer before painting.
