Technical Data Sheet AS1723 (ESP568-2) 1 Part RTV silicone adhesive sealant flowable non corrosive Introduction Property Test Method Value AS1723 is a translucent, liquid one part, non corrosive, Uncured Product condensation curing silicone elastomeric adhesive, specifically Colour: Translucent formulated to meet the needs of the electronics industry. It features Appearance: Viscous liquid fast skinning with good self levelling properties and is compatible Tack Free Time: 11 minutes * with many sensitive substrates including copper and brass, steel, 3mm Cure Through: 24 hours * aluminium and FR4, making this an ideal option for many Viscosity 72000 mPas electronics applications such as coating or shallow depth potting. * measured at 23+/-2C and 65% relative humidity. Key Features Cured Elastomer (after 7 days cure at 23+/-2C and 65% relative humidity) Self levelling Tensile Strength: BS903 Part A2 1.00 MPa Low odour Elongation at Break : BS903 Part A2 216 % Suitable for sensitive substrates Youngs Modulus: 0.30 MPa Modulus at 100% Strain: BS903 Part A2 0.43 MPa Use and Cure Information Hardness: ASTM D 2240-95 28 Shore A Specific Gravity: BS 903 Part A1 1.03 Typical Applications Thermal Conductivity: 0.20 W/mK Coefficient of Thermal Expansion: Assembly of electrical and electronic equipment Volumetric 884 ppm / C Sealing of corrosion sensitive devices Linear 295 ppm / C Shallow encapsulation of small circuits and connectors Min. Service Temperature: -50 C Max. Service Temperature: AFS 1540B 200 C Application and Cure Electrical Properties After removal of the package seal the product is ready for use. It can be applied manually or using a pneumatic caulking gun. Volume Resistivity: ASTM D-257 4.71E+15 .cm Following exposure to atmospheric moisture the product begins to Dielectric Strength: ASTM D-149 >18 kV/mm cure to a resilient, durable silicone elastomer. Full cure will depend Dielectric Constant at 1MHz: ASTM D-150 2.72 on the relative humidity and ambient temperature. At 20 to 30C Dissipation Factor at 1MHz: ASTM D-150 0.0011 and 40 to 70% Relative Humidity a 3mm section will normally cure in less than 24 hours. Adhesion Testing The volatile by-products of the curing mechanism are relatively inoffensive alcohols. AS1723 will adhere to most substrates but the use of a primer may (See Health and Safety Data) be required for some applications. Please contact your regional Full bond strength and physical properties will be achieved in 7 ACC Sales Manager for further information. days. Customers are advised to carry out their own tests on clean, Cure time depends on the thickness of sealant applied and the degreased substrates to ensure satisfactory adhesion is achieved area exposed to the atmosphere. It is recommended that a minimum thickness of All values are typical and should not be accepted as a specification. 1 mm is achieved between parts to obtain best adhesion to substrates.
