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.
Electronic
applications cover the full range of adhesive, sealant, coating
and potting requirements. Guidelines for product selection are primarily
based on speed of cure to allow handling of assembled product and subsequent
environmental exposures.
Epoxy
based systems have the best humidity, water and chemical resistance
and produce tack free surfaces almost immediately, even with low power
UV lamps. This type of chemistry can often develop acceptable bond
strengths within seconds of exposure but final properties are realized
12-24 hours at ambient or after post UV heat treatment. Vinyl systems
produce final properties almost immediately after UV cure and provide a
complimentary set of products to offer to customers.
