Overview
Built for the job.
1K seam sealer nozzles are for use with our 1K seam sealers.
The SEM 29352 1K Seam Sealer Nozzle is a single-component sealant designed for sealing seams and joints in automotive body repair. It is supplied in a nozzle format for precise application on panels, trim pieces, and structural components where a reliable, flexible bond is required.
Key technical features include a work time of 5-10 minutes at 70 °F (21 °C), allowing sufficient open-time for placement before the material begins to set. Full cure is achieved in 24 hours for a 4 mm film thickness under the same temperature conditions, providing rapid return to handling and subsequent coating steps. The formulation adheres well to aluminum, OEM primer, steel, and other primed substrates, making it suitable for a range of body shop applications.
Use with appropriate personal protective equipment-gloves, eye protection, and respiratory protection when ventilation is limited-as the product should be stored in a cool, dry, well-ventilated area to maintain its shelf life.
