I selected AWLGRIP for my boat.
AWLGRIP topcoat uses a polyester urethane resin ...........Awlcraft 2000 uses an acrylic resin.
The difference is molecular size. Quoted from AWLGRIP volume 3 brochure
"Polyester molecules are much smaller than acrylic molecules. A given volume of polyester resin contains many more molecules than the same volume of acrylic resin. Thus the polyester has more reaction sites than the acrylic. When both are fully crosslinked, the polyester forms a tighter, tougher film. The more dense crosslinking provides a harder, more abrasion resistant film, with better chemical resistance than the acrylic film". |
