840 Denier Junior Ballistic: Original & Primo 


Back in stock is our Original and Primo 840 den. Jr. Ballistic Nylon. Both are proven on countless 1000s of skin on frame kayaks, canoes and other small boats.  Both are lightweight, shrinkable,  and a perfect marriage for our 2 part urethane system. Also with our rare earth pigments,  both can be tinted while still staying very translucent. With our coating system, the 840 den is the recommended fabric for kayaks, canoes, and other small water craft.

840 Original Characteristics: OUT OF STOCK!!  SEE 840 PRIMO or EXTRA TUFF

The  840 den original fabric has been the preferred cloth of Aleut Kayaks (Baidarka’s) and or for boats with complex curves. It has a more open weave construction,  allowing the fabric to stretch more and thus suck in convex curves.  This looser weave also allows more shrinkage when completed. The down side to this is the needle holes created under stress are slightly larger then you will experience with the 840 primo. Also we do not recommend dying any of  the skins, but if you must, the 840 original fabric will take the dye better and less likely of issues in long term use. As with all we recommend using our rare earth pigments for tinting. 68" wide.

840 Primo Nylon Characteristics:

The 840 Primo has been the favorite for many who build hard chine boats.  Works great on west Greenland Kayaks, and other boats with more flat panel shapes.

The 840 Primo is extremely shear.  Its very flat and smooth and is the most simple for finishing. Always gives a flat glass finish.  The 840 Primo will give you a more translucent boat. Also due to its denseness, it will take less coating, thus it will be lighter weight than the 840 original upon completion.  This denser construction also will give you the smallest needle pulls.  Because of its tight weave it does not stretch as much as the 840 org and it is recommended sewn wet (especially in warm climate).  We do not recommend using the acid nylon dyes with the 840 primo. The weave is very tight and the dye makes a barrier. This barrier does not  allow the coating to saturate and integrate with the fabric as well. We have seen delamination issues, and dye wash from the inside after 3-5 years of use. 68" wide.

 In result of customer requests and saving resources, we will offer these goods by the foot.
