materials are solventless, one part, room temperature stable
and are available in a range of viscosities and thixotropies as well as
a variety of cure options. UV and visible cure systems may be combined
with, or converted to, heat cure or two part/UV products.
Light
can be used to harden exposed regions and heat or time to finish
shadowed or deep areas. Cure temperatures as low as 80o C are possible
and for epoxy chemistry; tack free coatings can be obtained in as little
as 5 minutes at 100o C.
“Delay
cure” epoxy systems are options when opaque substrates are to
be bonded or as a means of achieving fast UV processing of epoxy adhesives,
with inexpensive CTECH™ lamps. For applications where weathering
is a concern ask for the “AY” additives package.
Some
rules of thumb follow: vinyl systems are used for fastest
fixture and for direct sunlight exposure. Epoxy systems generate
the highest bond strengths through humidity, water immersion, temperature
ranges and contact with chemicals. These systems work for glass to glass,
metal, ceramic and some plastics.
