Applications & Uses

Applications

• Bonds a wide variety of plastics in multiple configurations.
• Well-suited to bond dissimilar substrates

General Instructions

• Surfaces to be bonded should be clean and dry. Dispense a drop or drops to one surface only. Apply only enough to leave a thin film layer after compression. Press parts together and expose to UV dose when ready.
• An adequate bond should develop rapidly, depending on UV dose efficacy, and maximum strength is attained in 24 hours.
• Wipe off excess adhesive from the top of the container and recap. products, if left uncapped or exposed to sunlight, may deteriorate or cure prematurely.

Properties

Shear Strength:

20.67 MPa

Strain at Break:

175 %

850~1150 cps

Curing Performance

• Photoinitiation initiates the curing process. Handling strength is reached in a short time, and will vary based on UV dose efficacy, environmental conditions, bond line gap, and other factors.
• Product will continue to cure for at least 24 hours before full strength and solvent resistance is developed.
