I'm not finding any chemical makeup specs on DN
site for the topcoat product, does anyone have such, or do the containers/ instructions include this and safety notice? I am curious of the hazards and ventilation requirements etc... Does DN
I will use and completely endorse the DN
product if it is the easiest and most cost effective coating available for our purposes, but if I can find other products with same qualities or better I think its worth looking into and sharing here?
Moisture cure urethane seems to be the type of creature we are dealing with, and there are quite a wide array of these coatings, some with marine apps that look interesting.
A little (very tiny) light bulb flickered in my head when thinking about these urethanes. Years ago when touring a custom paint shop who did a lot of airbrush work and such here in Cali I remember something... They were using components that when I asked if I could have a sample they gave me some, but told me it would be useless in several days as it was self-catalyzing. As they said "it kicks" when contacted by air and once started the whole can will go.. This sounds very much like the type of stuff you guys are dealing with...
When I asked how they could store the products for periods of time without it curing on them they showed me a dispensing type rack that seemed to have containers with lids that not only drew off the product but replaced the missing volume with a condensed gas fed by a network of tubing to each container on the rack.
Essentially they were doing what you guys are with the Bloxygen stuff, making me think, why couldn't you make a small scale replica of this dispensing system with a couple valves attached to the lid of a container, one draws product from the bottom through a tube in container, the other receives the pressurized gas from a canister / tube assembly. Thus the product in the container would be under pressure making it easy to dispense and any time you draw an amount of product you would be replacing (equalizing) the containers volume with no air being permitted to enter the environment?
This sound plausible to anyone? And do we have any chemistry guys aboard? would such an easy compressed gas source such as CO2 canisters or airbrush propellant be viable or would that have negative reaction with the product? Wondering what readily available type of compressed canister gas would be most economical?
Just my thoughts for the day... maybe I've been breathing too many fumes, I did primer coat quite a number of baits this afternoon... Here's my primitive system and results... Hence why I would really enjoy finding a topcoat that is user friendly both in application and storage.
