Product description:
LOCTITE SI 5700 is an ultra clear, two-part silicone which cures at room temperature and can be accelerated by heat. Thanks to polyaddition technology, the product releases no by-products, has low shrinkage, is non-corrosive and health and safety friendly. LOCTITE SI 5700 provides high transparency with a high transmission rate and is used for potting applications in the Lighting, Electrical and Optical industries for LED channel or lenses, optical sensors or coating processes.

Steps to achieve the best adhesive results:
1. For best performance the mating surface should be clean and free of grease. Use LOCTITE SF 7063.
2. Special surface treatments can increase the bond strength and durability.
3. Best results are achieved utilizing a helix 8mm diameter, 24 element mix nozzle.
4. Dual Cartridges:
Insert the cartridge into the application gun and start the plunger into the cylinders using light pressure on the trigger. Next, remove the cartridge cap and expel a small amount of adhesive to be sure both sides are flowing evenly and freely. Attach the static mixing nozzle to the end of the cartridge and begin dispensing the adhesive. Purge and dispose of the first 3 - 5 cm from the end of the mix nozzle, as it may not be sufficiently mixed.
Bulk Containers:
Utilize volumetric dispense system to ensure proper mix ratio and utilize mix nozzle to obtain adequate mixing.
5. Excess uncured adhesive can be wiped away with organic solvent (e.g. Acetone).
6. Certain materials can inhibit the curing of LOCTITE SI 5700, such as organotin compounds, sulfur-containing materials and amine-containing materials.
