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
provides visualization
aid for positioning.
