: I have always cringed at your insistence on using a roller to apply
: resin instead of my dump-and-spread method with a squeegee. I've
: always felt that a roller tended to froth-up the resin too much.
: However, It seems that several years ago something changed in
: the MAS formulation which caused more bubbles. I have to work
: harder to avoid bubbles now than I used to. If MAS had more
: tendency to foam/froth up before relative to other brands it
: appears that the characteristic has increased.

: I have talked to the folks at MAS about the issue and they insist
: that nothing has changed, but I am not the only one who has
: noticed. Your comments here suggest that we probably aren't
: imagining things.

: I am still getting good results with my methods, but the care I
: take is slowing me down.

: I second your comments about being cognizant that different resins
: work in different ways. I can't say I have ever been happy with
: all of your recommendations for clear layups because they didn't
: leave much room for variations in how different epoxy systems
: handle. I.e. rolling vs squeegee.

: EpoxyWorks magazine from Gougeon/West System just had a good
: article about bubble free coating and they recommend flow
: coating, pouring from the bottom of the container and using a
: blow torch to eliminate bubbles, so it is obvious that there are
: many ways to approach the problem. I guess it does say something
: about the safety of using epoxy around open flames if a blow
: torch is OK.

I use West's 105/207 and I too use the roller method, specially for fill coats and the bubbles disapear. I suspect it has much to do with the viscosity of the resin, but it may well be something else.

Course I also varnish with the roller and get no bubbles in the varnish either, so technique obviously has something to do with it.
