Production savings resulting from the primary advantage of speed of cure include fewer part handling fixtures; less floor space requirements; ability to test parts soon after assembly, eliminating the possibility of scrapping a large quantity of work-in-process goods; and inventory reductions.
Secondary advantages are that UV adhesives often can replace solvent based adhesives, thus eliminating the problems associated with environmental regulations on solvent emissions. Energy savings are often substantial as UV curing products eliminate the need for long oven cures, or for gas fired fusing operations in glass assemblies.
UV products often require no premixing as is common with epoxies, and consequently there is no pot life problem and subsequent waste, and no expensive meter-mix equipment. Parts will not fixture or begin cure until exposed to UV light. Critical part positioning is therefore enhanced.
Loctite UV curing adhesives are extensively used in the electronics, automotive, medical and other industries, especially those where glass and transparent plastic components are involved. In the automotive industry, applications |

include headlamp and mirror bonding. In medical devices, Loctite's UV adhesives are used to bond plastic and glass tubing and needles to other metal and plastic parts. In electronics, these UV adhesives are used in the hard disk drive, floppy disk drive, video tape recorder, compact disc, speaker and office equipment industries, to name a few.
Loctite's UV range includes products for instant curing at low UV intensity. They are especially suited to the electronics, electrical, glass, ceramic and other industries for wire tacking, component .bonding, small part encapsulation and shallow potting. In addition, Loctite produces general purpose glass to plastic bonders, an optically clear product, as well as UV adhesives for conformably coating and masking printed circuit boards. Medical grades are also available. Loctite Corporation has also developed multicure products to enable opaque products to be fixtures instantly with UV light which allows the secondary cure mechanisms to fully cure the adhesive off the assembly line.
