Features

• Shorter processing time• Superior depth of cure• Cure-on-demand performance• Cure when exposed to UV or visible light• Resistant to corrosion• Manual, semi-automatic or fully

automatic dispensing

Applications

Perfect for a broad range of PCB, componentand micro assembly applications including:

• Electronic encapsulation • Wire tacking• Electrical potting • Sealing• Fixturing • Lens bonding• Conformal coatings

Advantages

UV Curing:

• Ideal for thin films, thin coatings and bondingapplications on heat-sensitive substrates

• Provides long pot life• No special storage required

Visible Light Curing:

• Ideal for curing through thicker sections• Cures through colored or UV-absorbing

materials• Poses fewer safety risks to eyes and skin• Lower energy consumption and

maintenance costs

LC-1214 color shift to

yellow indicates exposure

to curing light.

Red color of LC-1214
