A d h e s i v e a p p l i c a t i o n a n d curing c o m b i n e d in o n e s y s t e m Xenon Corporation, MA, USA, has achieved the combination of an adhesive dispensing system with an ultraviolet light source in a single hand-held assembly for the curing of small-area applications. In the RC-256, the light source draws on pulsed uv curing technology from Xenon and is emitted from a 'liquid-lite-pipe'. The adhesive is dispensed from a storage tank through a concentrator nozzle. The output end of the liquidlite-pipe and the adhesive nozzle are brought together in a hand-held assembly, as shown in Fig. 3. Typical applications for the RC-256 include: fibre optic connections; printed circuit board cover coat reworking; wire tacking; and surface mounting.

Advertised for locking bolts, holding pins, filling holes and tacking wires, Bond it (Fig. 2) from Cotronics, NY, USA, is a second generation cyanoacrylate adhesive. It is said to form a bond in 1 0 - 4 5 seconds with a variety of materials other than Teflon-type plastics. It is further claimed that it will act as a filler and set by itself to a hard, machinable plastic.

Chloroprene rubber-type adhesives manufacture Designed specifically for use in the preparation of adhesives in a solvent medium, Butaclor M A 42, a type of chloroprene rubber, is offered as a means of economizing in the milling process of adhesives manufacture. It does not contain microgel and, compared with standard chloroprene rubber types, it is said to enable the manufacturer to use 1 0 - 2 0 % less polymer to obtain adhesives with the same viscosity. It is therefore possible to improve the rheological behaviour of the adhesive while maintaining the same bonding properties.

Air Products and Chemicals Incorporated, PA, USA, specialists in developing curing agents, has recently introduced Amicure 101, a curing agent for use in epoxy resin systems. Suitable for use in

adhesive systems, Amicure 101 is said to improve pot life, shorten gel time, and lead to high heat distortion temperatures in formulations. A low viscosity liquid, it has been developed as an alternative to MDA. A data sheet giving details of Amicure 101 may be obtained in Europe from: Air Products
