Product Description
DOWSIL 3145 RTV MIL-A-46146 Clear Adhesive Sealant For Electronic Module Sealing
Basic Properties

DOWSIL™ 3145 is a one-part, clear, room-temperature-curing silicone sealant compliant with MIL-A-46146 Group II TY I military standards. It features high tensile strength (864 psi), high elongation (626%), and excellent electrical properties (dielectric strength 485 V/mil), making it ideal for sealing and assembly in electronic devices.

Product Description

DOWSIL™ 3145 cures without mixing or heating, achieving tack-free in ~63.8 minutes at 25°C and >90% physical properties within 24-72 hours. Its non-flow特性 (0.092-inch slump) and low viscosity (168 Pa-sec at 10/s) enable precise dispensing, while offering superior unprimed adhesion to metals, ceramics, and glass (lap shear strength 336 psi on aluminum).

Key Features
  • Military Compliance: Certified to MIL-A-46146 Group II for reliability in harsh environments.
  • Electrical Insulation: Volume resistivity 4.4×10¹⁴ ohm*cm, dielectric constant 2.83 (100 Hz-100 kHz), ideal for high-frequency electronics.
  • Temperature Resistance: Operational from -45°C to 200°C long-term, with short-term tolerance to -55°C or beyond (verification required).
Applications
