( 2 ) Neoprene glue must be mixed with accelerator in the proportion of 100 percent
glue plus 5 percent accelerator over and above the volume of glue (100% glue
plus 5 % accelerator equals 105% total). The can of glue is marked to indicate
thirds of a container. One-third of a container of glue can be mixed with one full
bottle of accelerator.
( 3 ) Polyurethane glue and methyl-ethyl-ketone (MEK) solvent are used to glue
strongan fabric and molded PVC parts such as the keel, roll up floor, carrying
bag, carrying handles, and D-rings (except towing D-rings). Do not use PN
7096 glue on neoprene coated fabrics such as the buoyancy tubes, except
when one of the Strongan or PVC items identified above is being glued to
hypalon neoprene fabric.
NOTE:
The PN 7096 is for a 750 cc container of polyurethane glue and 3 small bottles of
accelerator. The mixing procedures are identical to those for the neoprene glue
(100% glue + 5% accelerator =105%). The part number changes with different
size containers as follows:
PN 7096 one 750 cc Container
PN 7097 six 750 cc Containers
PN7124 one 250 cc Container
Mixing Glue. Verify that the glue you are using is fresh. Check the expiration date on the
b.
container. Stir the glue to dissolve any solids that settle to the bottom of the can.
( 1 ) Both the PN 7098 (neoprene) and PN 7096 (polyurethane) glues must be
mixed with a precise amount of their accelerator before they are used. A clean
container should be used to mix the glues. A plastic container can be used
providing it withstands toluene and MEK solvents. A clear plastic container
marked in cc s is useful for mixing glue in the correct proportions. A plastic
eyedropper with graduated markings in cc s is useful for measuring the 5
percent accelerator which must be added to the glue. Refer to appendix D for
solvent resistant container part numbers.
( 2 ) Wooden stirring sticks ( tongue depressors) are normally used for mixing the
glue with the accelerator. The glue must be stirred for two minutes after the
accelerator is added. Mix only the amount of glue you plan to use in 60
minutes. Glue becomes unusable after 60 minutes indoors and after 30
minutes outdoors and must be discarded.
