8、procedure for seam sealant. a. Arrange the sewn seam flat onto a hard surface in such a way as to expose the stitched areas. Prepare surface for sealing by removing surface contaminates (talc, etc.) with process suitable for the seam sealer (see Para 3.2.1.4). Apply sealant to both sides of seams st

9、itching. The sealant bond to the cloth (see para 3.2) shall be at least 15 pounds per linear inch when tested as specified in ISO 2411 b. Using a firm bristle brush, apply the sealant to the exposed seam, working the sealant under any overlapped seam flaps or so called “French Laps”. Having applied

10、the sealant, press the flaps back over and onto the drying sealant. c. Brush the sealant thoroughly over the stitching to penetrate and fill the needle holes. d. Allow sealant to dry for 10-20 minutes. High humidity retards drying of sealant e. Apply a generous second coat of sealant after the first

11、 coat has dried tack free. f. After the final coat has dried tack free, rub talc lightly onto the seams to avoid newly sealed areas from sticking together when folded. 3.2.1.3 Thread, stitching, and seams. a.
