Dow Chemical Launches Military-Grade DOWSIL™ 3145 RTV Sealant, Redefining Reliability Standards for Electronics​

Breakthrough in Material Science​
Amid growing demand for miniaturized electronics and extreme-environment applications, Dow Inc. (NYSE: DOW), a global leader in material science with 130+ years of innovation, introduces DOWSIL™ 3145 RTV one-part silicone. This gray adhesive/sealant meeting MIL-A-46146 specifications is revolutionizing sealing solutions for aerospace, automotive electronics, and industrial equipment.

Core Performance: Redefining Industry Standards​

1. ​Engineered Performance without Mixing​
   As a polydimethylsiloxane-based material, its 121g/min extrusion rate (TDS data) and zero slump (0.1in/0.2cm) enable precise vertical application. Achieving >90% strength within 24-72 hours after 78-minute tack-free time (25°C) dramatically reduces production downtime.

2. ​Extreme Environment Stability​
   DSC tests confirm elasticity retention at -42°C (TDS hardening transition data). Operating range (-45 to 200°C) coupled with 1035psi tensile strength and 670% elongation (TDS Typical Properties) ensures sealing integrity under thermal shock.

3. ​Military-Grade Endorsement​
   MIL-A-46146 Group II/III, TY I certification (TDS Mil Spec) validates performance against vibration, humidity, and salt spray. UL 94 recognition further expands consumer electronics applications.

Productivity Revolution: Every Drop Reduces Cost​
"Conventional thermal curing consumes 23% of production line energy," states Dow's Electronic Materials Technical Director. "DOWSIL™ 3145 eliminates oven investments, with 10-120 minute handling time (TDS Description) boosting line efficiency by 40%."
Accelerated curing below 60°C benefits cycle-sensitive operations like automotive electronics. Twelve-month shelf life (25°C) and diverse packaging (100ml syringes to 200kg pails) optimize inventory management.

Applications: From Microchips to Spacecraft​

• ​Advanced Electronics: 51 Shore A hardness (TDS Durometer) cushions components on PWBs while 190ppi tear strength (TDS Tear Strength) resists thermal stress
• ​Aerospace Sealing: Implemented in wire passthroughs, maintaining airtightness after -55°C thermal cycling (TDS Low-temp performance)
• ​Mechatronics Integration: 106ppi adhesion (TDS Primed Adhesion) ensures yoke assembly integrity through 50,000-hour vibration tests

Sustainability Commitment​
Dow's Product Stewardship (TDS documentation) governs the lifecycle: 96.2% non-volatile content reduces VOC emissions, nitrogen-purged packaging minimizes waste. Global technical teams on dow.com deliver customized solutions, actualizing "Material Science for Sustainable Development".
