Clear Silicone Adhesive DOWSIL 3145 RTV One Part for Electronic Component

DOWSIL 3145 RTV Electronic Component Sealant Clear One-Part Silicone Adhesive

Product Introduction of DOWSIL™ 3145 RTV MIL-A-46146 Adhesive Sealant-Clear

Part 1: Basic Properties

DOWSIL™ 3145 is a one-part, clear, room-temperature vulcanizing (RTV) silicone sealant compliant with MIL-A-46146 Group II Type I. It features high tensile strength (864 psi), elongation (626%), and dielectric strength (485 V/mil). No mixing required, ideal for electronic and industrial sealing.

Part 2: Product Description

DOWSIL™ 3145 cures via moisture to form a flexible elastomer with broad temperature resistance (-45°C to 200°C) and weatherability. Its non-flow properties suit vertical applications, and cure speed can be accelerated with mild heat (<60°C). Typical uses include electronic module sealing and PWB assembly.

Part 3: Key Features

1. Military Compliance: MIL-A-46146 Group II tested for harsh environments.
2. ​Electrical Stability: Volume resistivity 4.4×10¹⁴ Ω·cm, dielectric constant 2.83 (100 Hz–100 kHz).
3. ​Fast Processing: Tack-free in 63.8 min (25°C), 90% properties in 72 hours.

Part 4: Applications

1. Electronics: Sealing sensors/relays against moisture and contaminants.
2. ​Aerospace: Avionics housing sealing per MIL-SPEC.
3. ​Automotive: Waterproofing ECU modules and wire harnesses.
