~Features:
1.Two-component,neutral curing,odorless, non-corrosive cure system ，high adhesion, high strength capacity.
2.High optical transmittance and thermal stability, stress-relieving.
3.Good compatibility with other neutral silicone sealants.
4.Heated to cure to a elastomer.
5.Uncured, both the A and B components are thixotropic pastes, when mixed, cure quickly to an extremely tough elastomeric silicone rubber ensuring a durable, flexible, watertight bond upon exposure to atmospheric moisture.

6.Can be used for a long period at the temperature of -60~300 centigrade degree.

Main applications :  
1.It is good used for LED display,pixel tube for potting.
2.It is application for DC/AC module and circuit board which requires heat dissipation and high temperature resistance.
3.It can be broadly used for LED screen, wind power generator, PCB substrate, etc.
Limitations:
1.Is not appropriate for all will be leaking oil, plasticizer or solvent surface.
2.Not for frost or wet surface.
3.Is not suitable for the place of continuous immersion or year-round moisture.
4.Can not ontact with strong acids or bases.
5.Joints where abrasion and physical abuse are likely to be encountered.
6.Hasn’t performed adhesion and compatibility tests on project substrates, spacer materials and all accompanying accessories.

Installation:
1.Characteristic test:A structural glazing sealant should have at least its curing and adhesion characteristics periodically checked during fabrication and installation.
2.Surface preparation: Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application.Using proper materials and  and cleaning procedures is vital for sealant adhesion.
3.Cleaning materials:clean, fresh solvent; clean, white cloths free of lint or other lint-free wiping materials; primer (when required).
4.Cleaning procedures:Remove all loose material (such as dirt and dust), plus any oil, frost or other contaminants from the substrates to which the structural silicone will be adhered. Do not usedetergent to clean the substrate as residue may be left on the surface. Wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface before it evaporates. Change the cleaning rags frequently, as they become soiled. If cleaned areas are again exposed to rain or contaminants, the surface must be cleaned again.
5.Primers: LE331Silicone LED encapsulant will bond to many clean surfaces without the aid of a primer. For difficult-to-bond substrates, the use of a primer or special surface preparation should be evaluated.

Emergent Treatment:
Keep out of reach of children. Once it contacts skin or eye by accident, rinse the affected part with water for 15 minutes or turn to doctor for help immediately.

Shelf Life:
A component 1 years, B component 6 months from the manufacture date stored in cool & dry place below 27 ℃.

Color:

LE331 Silicone LED encapsulant is available in transparent.

Packing/ Mix Ratio:
