Aerolite is a
urea-formaldehyde gap filling adhesive which is water- and heat-resistant. It is used in large quantities by the
chipboard industry and also by wooden boat builders for its high strength and durability. It is also used in
joinery,
veneering and general woodwork assembly. Aerolite has also been used for wooden aircraft construction, and a properly made Aerolite joint is said to be three times stronger than
spruce wood.
