Re: Fillers, primers and UV protection

[DuncanMcFadyean <101234.3202@compuserve.com>]

The weight of other primer- fillers (which are heavily loaded with TiO2 and
Barytes) typically work out at a mind-numbing SG of 2.0 to 2.4  If water is
10lbs/imp. gal. then this works out to a weight of 20 to 24 lbs/imp.gal (ie
dry-film density, what you buy in the tin is less because of the solvent
present).

The potential weight savings with a lightweight alternative are huge.

Would be glad of any and all further information you can obtain.
