DOWSIL™

Liquid silicones for electronics

They flow into narrow gaps to bond, coat and encapsulate parts, and to carry heat away. We recommend room-temperature or heat-cure grades to suit your process.

Dispensing & curing equipment

Equipment matched to your material

We choose the dispensing method that suits the material and your process conditions, and propose dispensers and curing units suited to your process.

After confirming conditions through trial dispensing and on-site demos, we build and install equipment, from benchtop units to systems that fit into your line, and support you into production. UV LED curing units replace conventional lamp systems, cutting power use and maintenance costs. IR LED curing units cure with near-infrared light, taking far less time than chamber or oven processes.

Ask about equipment Dispensing & curing uses

What we propose

We review the material, the dispensing method and the equipment together.

Dispensing method

We choose dispensing, spraying, hot-melt or filling to suit the material and the part.

Dispensing equipment

Benchtop robot dispensers and turntable or 3-axis dispensers, configured for your process.

Curing equipment

UV and IR LED curing units, built into the dispensing system or set up separately.

Line & auxiliary equipment

We also review filling, packaging and conveying equipment, presses and other upstream or downstream steps.
