Ideally, an assembly adhesive should offer and desired strength upon curing. More
importantly, it should allow the user to decide when and where (during the
production cycle) curing will take place. Over the past decade, many manufacturers
have begun using ultraviolet-curable, structural-strength aerobic adhesives and
coatings, because they just offer those features.
These materials were originally used for glass bonding, structural pothng, headlamp
assembly, and other automotive applications. Today, the range of applications has
expanded to include electronics assembly, medical disposables, jewlery, glassware,
auomotive, electrical equipement and more.
Unlike many other adhesives, UV-curables readily bond dissimilar substrates, even
inherently incompatible substrates. And they offer rapid curing at room temperature
to true structural strength. Moreover, they tend to be fairly forgiving of moderate
amountsof surface contamination and less precise juncture tolerancesl
Aerobic acrylic adhesives serve as bonding agents and can be also used ( at the
speed required by an efficient assembly process) as high-adhesion protective
coatings, sealants, and pottings. An important benefit is the ability to readily and
subtly modify formulations to impart differing cured properties, yielding custom
formulations for specific end uses. As a results, the product-line of Dymax UVadhesives
compromises more than 150 standard formulations and 1200 custommade
adhesives.
