Welcome to the wonderful world of bio based foams. We have tried two different kinds and had similar results with both of them, just not worth the hassle for a little break in price.

When you say substrate good, what was the substrate temp? What was the moisture content of the substrate? Air temp? What kind of heaters were you using if any? What temps were you spraying at? What pressure? What was the substrate, wood, metal, etc?

Tried twenty sets of bio based foams in two different trailers from GA to AZ. We ran designed experiments across temp, pressure, bbl temp and mix times. In short we never found a consistant solution. The bio stuff is junk.

There are many bio-based foams out there, just because you had bad experiences with a couple doesn't mean that they are all bad. It is unfortunate that there are alot of foam companies that are unable to help you when you are having problems. I get more and more calls from guys having trouble with the foam and their supplier is unwilling or unable to help.

I disagree, I have tried several bio based and none of them have been as good as the BASF that I spray. I also enjoyed spraying Demilec Heatloc until they switched to bio based. The junk sucks.
