Applications & Uses

Markets: Electrical & Electronics
Applications: Electrical & Electronics — Devices & Assemblies
Other Devices & Assemblies
Plastics & Elastomers End Uses: LEDs,
Lenses
Plastics & Elastomers Processing Methods: Injection Molding,
Liquid Injection Molding
Applications: For molding or casting hard, non-yellowing lenses for LED, solar or other applications where a hard, optically-stable silicone is needed

Viscosity is designed to be used with conventional Liquid Injection Molding equipment, and the material is self-leveling for casting application techniques
Instructions for Use: Mixing

Use with mix and dispense equipment in a 1:1 mix ratio. If mixing by hand, take care to minimize air entrapment.

Vacuum Deaeration

Remove air entrapped during mixing by common vacuum deaeration procedure, observing all applicable safety precautions. Slowly apply vacuum, up to 28 inches Hg, to a container rated for use and of volume at least four times that of material being deaerated. Hold vacuum until presence of air is no longer evident.

Substrate Considerations

Cures in contact with most materials. Exceptions include sulfur cured organic rubbers, latex, chlorinated rubbers, some RTV silicones and unreacted residues of some curing agents.
