Since that dark day when Walmart quit carrying Devcon 2 ton epoxy, I've started buying Devcon 2 ton in quantity. I buy the 9 oz stuff.
Problem: Where to find a cheap dual-syringe to facilitate ease of application.
I often mix only a small quantity and the dual-syringe is the most accurate way to do that.
Anyone know of a source for double-syringes other than buying the Devcon in the one ounce package and using the syringe over again? (The syringe that comes with the 1 ounce package does not like to be used again...you can do it, but it is difficult and the handle will break easily.)
Since walmart stopped selling this, I went to a different clearcoat and I was not happy with it, so I ordered the 9 oz bottles and did some research while waiting for it to arrive. I wanted to weigh it out instead of messing with the syringes. The technical data says 1:1 ratio either by volume or weight.
Color - Clear
Mixed Viscosity- 8,000 cps
Mix Ratio by Volume- 1:1
Mix Ratio by Weight- 1:1
Mixed Density- 9.17 lbs/gal.: 1.10 gm/cc
Working Time- 8-12 min. (28 gm @ 72°F)
Fixture Time- 30-35 min. @ 72°F
Functional Cure- 2 hrs. @ 72°F
Full Cure- 12 hrs.
Service Temperature-Dry, -40°F to 200°F
I know this is not really a answer to your question, but perhaps another option.
P.S.- I picked up a cheap scale at Harbor Freight.
Hope this helps.
