The following evaluation comprises my report concerning Liquiguard PC for base coat use on various pieces of new aluminium and used steel stock procured by my company in advance of routine powder coating.

All metal samples were initially outgassed and and then prepared and powder coated under the same stringent conditions including powder mill thickness of 0.03 mils and similar placement of the same part in the curing oven, in order to compare them as closely as possible.

 
Metal prep-use steel : Media blasting, soap/water, acetone
Metal prep-use new aluminium         : Soap/water, acetone
Outgassing temperature     : 425 degrees
Outgassing duration            : 60 minutes
Powder gun voltage setting : ± 5,000 kv
Relative humidity                : 33%
Ambient temperature         : 56º
LiquiGuard dry/set up time : 15 Minutes
Oven temperature – flow out : 425º (7 Minutes)
Oven temperature – curing : 400º (20 Minutes)

 
 
Following the initial outgassing and cool-down period, LiquiGuard PC was sprayed onto the samples using a commercial spray gun, lightly blown dry with compressed air, and allowed to set up undisturbed for fifteen minutes.

Although the samples would initially somewhat repel powder adhesion, once a very light layer of powder was applied, it produced very nice adhesion results, attracted the powder extremely well, and seemed to be smooth and even.

The most impressive part of my evaluation pertains to the total absence of any outgassing whatsoever during the curing cycle. Even on the thinnest gauge aluminium I could find, there was no outgassing at all, as is typical in the industry, and as all powder coaters have come to expect when dealing with aluminium. I am extremely impressed with and excited by the results I received using LiquiGuard PC on aluminium. It may well be every professional powder coater’s “dream products”. The sample coated with LiquiGuard PC are smooth, orange peel is minimal, and produce superior aesthetic results to the trained eye.

Thank you very much for this latest opportunity to assist your company with its testing and product development.
