Multi-Cure® 9-20801 cures upon exposure to UV light, heat and/or activator and is designed for rapid mounting of heat-sensitive components on printed circuit boards to provide highly conductive bonds to heat-dissipation elements such as heat sinks. 9-20801 thermal interface material is a Multi-Cure® material specially formulated to cure with heat or activator between opaque substrates. Most high-speed processes call for dispensing 9-20801 on the substrate surface and then applying a thin layer of Dymax 501-E activator to the opposite component surface. The parts are mated and then exposed to light. This exposure cures the edges of the component in seconds so the parts are fixtured allowing for immediate handling and movement to the next step in the process. Material between opaque surfaces will cure over time, typically minutes or hours. Light cure allows for exposed areas to cure in seconds, fixturing parts in place so a secondary cure can effectively cure shadowed areas without interruption to process flow.

Dymax materials are solvent free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.

Compare Dymax UV/Visible Light-Curing Spot Lamps
Dymax spot-curing systems provide very high intensity (3,000-8,000 mW/cm2 (320-395 nm)) over a small area (typically <½", 5 mm diameter). These intensities usually result in a 0.5-5 second cure time. Dymax spot-curing systems utilize an integral timed/manual shutter and typically require little external shielding. An intensity adjustment feature aids users in both validating and controlling a UV light-curing process.
Spot lamp systems are ideal for curing small areas quickly and can be easily integrated into an automated assembly process or used as a turnkey bench-top system.

Compare Dymax UV/Visible Light-Curing Flood Lamps
Dymax UV light-curing flood-lamp systems offer moderate to high intensity (75-225 mW/cm2) over a large area (5" x 5" or 8" x 8" (127 mm x 127 mm or 203 mm x 203 mm)). These lamps are ideal for curing areas larger than ½" (12.7 mm) in diameter or curing many small parts simultaneously.
Dymax UV light-curing flood-lamp systems can be incorporated into conveyors, automated assembly systems, or used as turnkey bench-top units.

Compare Dymax UV/Visible Light-Curing Conveyor Systems
Dymax conveyors incorporate either flood or focused-beam curing systems. The benefits of light-curing conveyors include consistent cure times and the ability to cure larger parts. Another benefit of conveyors is that they completely shield operators from UV light. Dymax conveyors have 12" wide belts, and can be configured for 6" and 12" width curing. Conveyor speed is tightly controlled and typically ranges from 1-27.5 feet per minute (although faster conveyors are available). Dymax light-curing conveyors can be outfitted with different types of lamps and up to four lamps on a single conveyor.
1These conveyors require 120 volts. 230 volt conveyors are also available.
