1. Specifications

The human eye can not detect "pure" UV light, only visible light. A radiometer should be used to measure stray

UV light to confirm the safety of a UV light-curing process. A workstation that exposes an operator to more than

1 mW/cm

of UVA continuously should be redesigned.

UV light-curing of adhesives can be a regulatory compliant, "worker-friendly" manufacturing process when the

proper safety equipment and operator training is utilized. There are two ways to protect operators from UV

exposure: shield the operator and/or shield the source.

SHIELD THE OPERATOR

•

UV-Blocking Eye Protection – UV-blocking eye protection is recommended when operating UV light-

curing systems. Both clear and tinted UV-blocking eye protection is available from DYMAX.

•

UV-Blocking Skin Protection – Where the potential exists for UV exposure upon skin, opaque, UV-

blocking clothing, gloves, and full-face shields are recommended.

SHIELD THE SOURCE OF UV

Any substrate that blocks UV light can be used as a shield to protect workers from stray UV light. The

following materials can be used to create simple shielding structures or blind corners:

•

Sheet Metal – Aluminum, steel, stainless steel, etc. Sheet metal should be coated black or black

anodized to minimize reflection of UV and visible light toward operators.

•

Rigid Plastic Film – Transparent, UV-blocking plastics (typically polycarbonate or acrylic) are commonly

used to create shielding where transparency is also desired. These rigid plastic films are available either

water-clear or tinted.

•

Flexible Film – UV-blocking, flexible urethane films can be used to quickly create workstation shielding.

This UV-blocking, flexible urethane film is available from DYMAX.

HIGH-TEMPERATURE SURFACES

Surfaces exposed to high-intensity curing lights will rise in temperature. The intensity, distance, exposure time,

cooling fans, and the type/color of the surface can all affect the actual surface temperature. In some cases,

exposed surfaces can reach temperatures capable of producing a burn or causing damage to a substrate. In

these cases, care must be taken to ensure a more moderate surface temperature or appropriate protection/

training for operators.
