LITTLE BASTARD, A GREAT SMALL KAYAK








WHAT SORT OF RESIN DID I USE ?

AN EXTREMELY UNSCIENTIFIC BALLISTIC NYLON / RESIN STRETCH TEST



As I was curious to find out which coating would result in the strongest skin in terms of
not easy to dent ( stretch ) I've set up an extremely unscientific test.






A woven fabric is most stable in line with the main fibres but not at a 45 degree
angle, Let's see what we get if we pull hard in that direction for a few hours.





I cutted some samples from the fabric I coated earlier, drove two holes in each one
44mm apart. Nailed the lot to a heavy board and attached a 10kg weight for
about
two hours " dangling " time. And now for the result ... The loser is, Alkyd resin
stretched up till 57 mm. Acrylic got as far as 53mm. Then Epoxy resin
stretched
up till 49 mm and G4 one part Polyurethane came out as
the big winner, 47mm only. So Polyurethane it is going to be.



G4 is of rather thin consistency and at least 3 coatings are needed to make
the skin watertight, The first coating is fully absorbed in the fabric and even
the backside becomes '' wetted " and that's good. Subsequent
coatings
are needed to fill the open space in the loose nylon weave. As I grew
tired of the incredible stench I opted for a final  ( third ) coating of
Owatrol. The only thing to do now is paddle this boat and enjoy





Let's see how she goes ...
