Description
Crestomer 1196PA is a low density, structural gap-filling core adhesive for use in sandwich construction where requirement is
for a strong, tough, highly impact-resistant structure. It is based on Scott Bader’s innovative urethane acrylate technology and
exhibits exceptional impact strength and toughness. Crestomer® 1196PA has been formulated to bond core materials such as
rigid PVC foam and balsa to cured or semi-cured FRP skins. Using Crestomer® 1196PA gives a significantly tougher and more
durable structural bond than a polyester resin/ glass structure or polyester bonding adhesive. In addition, Crestomer® 1196PA
provides significant weight savings, reduced styrene emissions and greatly improved cosmetics with the elimination of core
print through.
