AS1700

Technical Data Sheet AS1700 (1070) 1 Part neutral thixotropic adhesive sealant Introduction Property Test Method Value AS1700 is a specially formulated neutral cure silicone sealant Uncured Product designed for use with sensitive electronic assemblies. Colour: Translucent It is described as an alkoxy 1-part room temperature vulcanising Appearance: Translucent paste Tack Free Time: 10 minutes * (RTV) silicone sealant. The Alkoxy cure system produces a silicone sealant with excellent adhesion to most common substrates 3mm Cure Through: 36 hours * Extrusion Rate: 290 g / minute Viscosity mPas Key Features * measured at 23+/-2C and 65% relative humidity. Non corrosive Cured Elastomer Excellent primerless adhesion to many substrates (after 7 days cure at 23+/-2C and 65% relative humidity) Excellent dielectric properties Tensile Strength: BS903 Part A2 2.43 MPa Low odour Elongation at Break : BS903 Part A2 545 % Youngs Modulus: 0.54 MPa Use and Cure Information Modulus at 100% Strain: BS903 Part A2 0.61 MPa Tear Strength: BS903 Part A3 12.3 kN/m Typical Applications Hardness: ASTM D 2240-95 30 Shore A Specific Gravity: BS 903 Part A1 1.1 Assembly of electrical and electronic equipment Linear Shrinkage: 1 % Sealing of corrosion sensitive devices Thermal Conductivity: 0.20 W/mK Shallow encapsulation of small circuits and connectors Coefficient of Thermal Expansion: Volumetric 810 ppm / C Application and Cure Linear 270 ppm / C Min. Service Temperature: -50 C After removal of the package seal the product is ready for use. Max. Service Temperature: AFS 1540B 200 C It can be applied manually or using a pneumatic caulking gun. Following exposure to atmospheric moisture the product begins to Electrical Properties cure to a resilient, durable silicone elastomer. Full cure will depend on the relative humidity and ambient temperature. At 20 to 30C Volume Resistivity: ASTM D-257 2.1E+15 .cm and 40 to 70% Relative Humidity a 3mm section will normally cure Dielectric Strength: ASTM D-149 18 kV/mm in less than 24 hours. Dielectric Constant at 1MHz: ASTM D-150 3.00 The volatile by-products of the curing mechanism are relatively Dissipation Factor at 1MHz: ASTM D-150 2.5E-3 inoffensive alcohols. (See Health and Safety Data) Adhesion Testing Full bond strength and physical properties will be achieved in 7 days. 2 Overlap Shear Strength: ASTM D 1002 kg/cm Copper 3.98 Cure time depends on the thickness of sealant applied and the Aluminium 4.00 area exposed to the atmosphere. Stainless Steel 304 3.04 It is recommended that a minimum thickness of Polycarbonate 5.22 1 mm is achieved between parts to obtain best adhesion to substrates. Customers are advised to carry out their own tests on clean, degreased substrates to ensure satisfactory adhesion is achieved Revision date 12/12/2005 All values are typical and should not be accepted as a specification.
