relatively common synthetic resin based adhesive which bonds to many
materials both porous and nonporous. It is waterproof and resistant to
acid and most solvents. It is typically available as a 2-part liquid,
gel, putty, or paste.
harden as a result of heat and a chemical reaction between the two
parts of the mixture. They do not usually shrink as curing does not
rely on evaporation.
Epoxy has very
high wet and dry strengths. Setting time will vary based on the epoxy
type and can be from very fast (minutes) to very long (weeks). Some
varieties of epoxy contain metal powder such as aluminum, steel,
titanium, or brass to function as a filler.
formulas are non-shrinking and dry to a range of colors including
green, blue, gray, and black. Liquid, paste, and gel formulas typically
dry clear to tan in color. The liquids, pastes, and gels can generally
be cleaned and thinned using acetone, and are non-shrinking only if you
do not use thinner.
