Microwave-powered UV curing of heat-sensitive substrates

As efforts toward cleaner manufacturing operations increase every day, more wood, metal, plastic, glass and other heat-sensitive substrates, are being coated, bonded, sealed, encapsulated, marked, decorated, and then cured using UV lamps.

The robust Nordson® CoolWave 2® UV systems offer the most reliable, durable and cost-effective ultraviolet curing performance for a wide range of varied products and applications.

Dichroic-coated temperature stable glass reflectors for cooler operation
No internal gasketing virtually eliminates possibility of arcing
Greater application flexibility with range of precisely focused and flood reflector geometries

Wood and Building Products

Most woodworking and construction products are pre-finished using UV-curable stains, lacquers and top coatings to provide superior stain resistance and durability.

Wood Products:

Moldings and trim
Cabinets
RTA panels
Particleboard and MDF (medium-density fiberboard)
Pre-assembled furniture and case goods

Building Products:

PVC sheets and tiles
Pre-finished hardwood strip flooring and two- and three-layer engineered parquet
Cement-board siding
Window and door components

Automotive Product Manufacturing

UV curing is the preferred method in a number of automotive assembly operations that apply several UV-curable materials:

Liquids and powders used for exterior hard coats, protective topcoats and clear coats
Clear coatings for increased protection of interior trim
Printed inks for instrument panels and decorative overlays

Automotive Products:

Head/Tail reflectors
Exterior trim including moldings, weather stripping, alloy wheels, and body panels
Interior trim, such as dashboard panels, wood and PVC door and steering wheel trim
Decorative overlay for instrument panels

Electronic Product Manufacturing

Electronic manufacturing involves a very broad range of applications using adhesives and coatings and inks. The use of UV-curable adhesives is an effective method for potting, encapsulating or bonding small parts and interconnects, replacing more conventional methods.

Electronic Products:

Loudspeaker assembly
Die attachments
Strain reliefs
Magnet bonding
Flip chips
Wire tacking

UV-curable coatings and printed electronics are now commonly used during manufacturing to increase throughput, minimize handling, and allow for more efficient assembly processes.

Electronic Products:

Printed circuit boards
Cell phone keypads and displays
LCD displays
OLEDs
Semiconductors
Ribbon cables

Life Sciences/Medical Device Manufacturing

UV curing plays a significant role in the production of medical devices, from surface treatment, adhesive-based bonding, and pressure-sensitive applications, to product decorating with screen, offset, pad and ink jet systems.

Bonding Applications

Syringes
Guide wires
Tubing
Oxygenators
Medical tapes and transdermal patches

Marking and Decorating

IV bags
Syringes
Catheters
Arterial locators
Test strips

Coating Applications

Catheters
Guide wires

Wire and Cable Manufacturing

Bonding, marking and color-coding applications are routinely used in the manufacture of wire and cable manufacturing.

Wire and Cable Products:

Fiber optics are color coded for identification
UV-curable matrix material is used to bond optical fibers
Cable jackets are UV marked and coded for abrasion resistance

Optical Media (CDs/DVDs) Manufacturing

Reliable, durable quality is required in the manufacture of CDs and DVDs. UV curing delivers those results throughout the decorating, coating and adhesive bonding processes.

Optical Media Products:

Imaging of non-data side with screen-printed or ink jet ink
Clear coatings on data side to provide scratch and abrasion resistance
Optical Bonding of two plastic layers of media to produce DVDs

Pipe and Tube Manufacturing

High-speed pipe and tube manufacturing operations use clean, virtually instantaneous UV curing of the pigmented and clear coatings applied during production.

Pipe and Tube Products:

Galvanized tubing
Electrical and pneumatic conduit
Water pipes
