The demand for LED encapsulants is absolutely skyrocketing as uses and applications for LED lighting expand daily. Sign industry professionals are constantly looking for the best products that protect the LED installations that they are making for clients. Chem-Set potting and encapsulating products provide a crucial protective barrier between the LED lighting mechanism and moisture and environmental contaminants.

Let’s shine a spotlight on two popular LED encapsulants available here at Chemical Concepts.

ChemSet 412 Clear Electronic Potting Silicone

ChemSet 412 Clear Electronic Potting Silicone is a low viscosity, two-component, addition cure, silicone elastomer which will cure at room temperature or at elevated temperatures. It has a low viscosity, which allows for ease of flow around complex parts, providing electrical insulation and shock resistance.

A Few of Its Key Features:

• Medium viscosity.
• Fast room temperature cure.
• Low linear shrinkage.
• Transparent.

Specifications:
Durometer: 40, Shore A
Tensile Strength: 650 psi
Refractive Index: 1.40
Elongation: 150 %
Viscosity: 4,900 cps
Mix Ratio: 1:1
Gel Time: 28 minutes
Color: Transparent
Thermal Conductivity: 0.18 W/m-K
Specific Gravity: 1.00

Chem-Set 033 Gel

Chem-Set 033 Gel is a clear, tough, moderately cross-linked silicone elastomer, which has good room temperature cure adhesion to many substrates. Silicone gels are used to provide protection from vibration and thermal or mechanical shock. Silicone gels also provide excellent moisture protection.

Compared to the ChemSet 412 this encapsulating silicone is self healing and repairable.

A Few Potential Applications:

• Coating.
• Encapsulating.
• Potting.

Additional Details:

• Color: Transparent
• UV resistant
• Moisture protection
• Excellent dielectric strength
• Self healing and repairable
• Provides protection from vibration and thermal/mechanical shock
• Room temperature cure
• Can be accelerated by mild heat
• Operating temperature -55C to 204C (-67F to 400F)
• Self leveling
• Offered in side x side cartridges 50MLs to1500MLs
• Easy 1:1 ratio

Additional Products to Help With Your Installation

Once you settle on the product that will work best for your particular installation need, make the installation even go even more smoothly by getting the installation products that work seamlessly with the adhesives and gels.

Like the Nordson TAH 190-620 Static Mixer for 50ml Cartridges. The TAH 190-620 or Nordson 7701487 is a Bayonet style static mixer with 20 mixing elements and an element diameter of 6.35 mm (.250 in). This static mixer has an H Tapered tip allowing for fine adhesive dispensing. The 190-620H mixer is one of our most popular Nordson TAH nozzles for mixing and dispensing.

Or the TAH 190-620LL Luer Lock Mixing Nozzle for 50ml Gun. This TAH 190-620LL Series 190 Spiral Bayonet Mixer with Luer Lock contains manifolds and valves that separately ports two component materials directly into the mixer.
