Description

Momentive RTV615B – Clear Silicone Rubber Catalyst (0.1 lb Pack)

Momentive RTV615B Catalyst, when combined with RTV615A base, forms the well-known RTV615 silicone rubber compound. This addition-cure, crystal-clear silicone is widely used in electronics, aerospace, defense, and solar industries.

It provides:

• Excellent optical clarity, making it suitable for potting LEDs and solar cells to maximize light transmission.

• Outstanding environmental resistance, protecting against moisture, ozone, dust, and chemicals.

• Mechanical durability, with tensile strength of 920 psi (65 kg/cm²), elongation of 120%, and tear resistance.

• Electrical insulation, with dielectric strength of 19.7 kV/mm and volume resistivity of 1.8 × 10¹⁵ ohm·cm.

RTV615 cures at room temperature but can be heat-accelerated for faster processing. It cures in deep sections without exotherm, making it suitable for complex potting and encapsulation tasks.

Uses of the Product

• Potting solar cells for maximum light transmission.

• Encapsulation of LED assemblies for optical clarity.

• Protection of electronic components against vibration, moisture, and chemicals.

• High-reliability potting in aerospace and defense electronics.

• Clear protective coatings where component visibility is required.

Applications

• Solar Energy & Photovoltaics

• LED Lighting Systems

• Aerospace & Defense Electronics

• Industrial & Consumer Electronics

• Automotive Electronics & Sensors
