Product Description

DOWSIL 734 Flowable Adhesive Sealant - For Fine Joint Sealing & Field Repairs

Product Introduction of DOWSIL™ 734 Flowable Adhesive Sealant

Part 1: Basic Product Attributes

DOWSIL™ 734​ is a one-component, flowable silicone adhesive sealant with an acetoxy cure system. It cures at room temperature upon exposure to airborne moisture, offering self-leveling properties and ease of application. The cured material forms a tough yet flexible rubber, ideal for fine joint sealing and electronic component protection.

 


Part 2: Product Overview

DOWSIL™ 734​ is engineered for industrial sealing and bonding, featuring fast tack-free time (13 minutes) and deep curing (3mm depth in 24 hours). With outstanding dielectric properties (volume resistivity: 1×10¹⁵ Ω·cm) and thermal stability (-65°C to +180°C), it performs reliably in harsh conditions. Note: Acetic acid released during cure may corrode certain metals.

 


Part 3: Key Technical Properties

Property Unit Value Test Method
Viscosity at 25°C mPa·s 45,000 ASTM D1084
Tack-Free Time minutes 13 CTM 0099
Tensile Strength MPa 1.5 ASTM D412
Elongation at Break % 315 ASTM D412
Dielectric Strength kV/mm 17 ASTM D149
Volume Resistivity Ω·cm 1×10¹⁵ ASTM D257
Operating Temperature Range °C/°F -65 to +180 (-85 to +356) CTM 0159A
