Testing Pre-Cats and Conversion Varnishes
By Bernie Bottens | Posted: 03/22/2012 9:53AM
This begins a series of articles on new products that I have tested. Over the next few weeks, I will take each in turn and give you a glimpse of what happens with these coatings when you pick up the gun and spray. Then I’ll talk a bit about why you would want to use these particular coatings.
I’ve not had the pleasure as of yet of spraying the Chemcraft or the Sherwin Williams zero formaldehyde products. Hopefully, someday soon I’ll get that chance. So please, other than that it’s my job to work with M.L. Campbell on a daily basis, I also get opportunities to work with other products. But on this occasion, it was a matter of our need to bring these products to market and that means that my thumbs up is necessary before we place a stocking order. Why shouldn’t you benefit form that opportunity?
It was a busy week at work. Most weeks are like that but this one was also rewarding in that the day finally arrived when we were scheduled to do some new product testing. Along with that testing came the opportunity for me to fulfill my promise to those of you who read my articles. For months I have asked that you stay tuned because I would report back when I had the opportunity to spray the new zero formaldehyde products from M.L. Campbell. We also took this opportunity to test their new two-component water-borne polyurethane. And, we did a side-by-side comparison between their two pigmented conversion varnishes.
Why would someone want a zero formaldehyde coating? I am certain that there are those who read this who will be waiting a long time for that need to arise. And, for some, it will, perhaps, never come depending upon your niche market and your clientele. However, for those of you who spray solvent-based lacquers, these new products open up a whole new list of opportunities.
• Formaldehyde exposure is not healthy for anyone be it finisher or home owner.
• There is no formaldehyde release in the course of applying curing, installing and using these.
• They are, in addition, Greenguard certified.
• Their odor is very different – much less pungent and much less bighting both during application and afterward when drying/curing.
• They atomize easily and lay down very well right out of the can.
• They dry really hard.
• They scuff sand better and sooner than their formaldehyde-containing stable mates.
• They have great clarity.
• The “feel” under the fingers is wonderful.
• The look is really good.
