Rtv Silicone Sealant

Product Details:

PRODUCT DESCRIPTIONTechnology SiliconeChemical type Oxime siliconeAppearance Thixotropic pasteColour Clear / Black / WhiteComponents One component – requires no mixingCure Room temperature vulcanizingApplication Bonding /SealingAnabond 669 is a single component, non-slumping, lowodour, low volatile silicone adhesive/sealant. It isdesigned to provide reliable “formed-in-place” gasketsfor mechanical assemblies where high temperatures areexperienced. The material cures on exposure tomoisture in the air to form a tough, flexible, siliconerubber gasket. The product resists aging, weatheringand thermal cycling without hardening, shrinking orcracking. It has good adhesion to substratesaluminium, mild steel, glass, ceramics, corks and manyplastics.The product is used to seal various flanged surfaces anautomotive and general industry. Typical applicationincludes bonding of sensitive electronic components andsub assemblies, Weather sealing of most commonconstruction materials including glass, aluminpainted metal, granite and other stone, concrete, brickand plastics, ceramic tile grouting, sealing aroundshower-tub enclosures, tubs, sinks, urinals etc.

After skin formation, curecontinues inward from the surface. Optimum physical properties are reached after curing for 7 days at55±5% RH.The rate of surface/depth cure depends on the relativehumidity and temperature of the environmentof the adhesive and the area under the jointis extended at lower humidity levels.Curing tested at 30 ± 20C, 55 ± 5% RHSkin forming time –Surface cure, ATM-R017Depth cure, ATM-R015.Operating parametersApplication temperatureIn service temperatureShort exposureTypical properties of cured mCured for 7 days at 30 ± 20C, 55Physical PropertiesTensile Strength,ATM-R020 (ASTM D412)Elongation,ATM-R020 (ASTM D412)Durometer Hardness,ATM-R019 (ASTM D2240)General InformationThis product is not recommendedand/or oxygen rich systems and should not be selectedas a sealant for chlorine or other strong oxidizingmaterials.HandlingBefore handling, read product safety data sheets(MSDS) and container labels for safe use.Directions for useSubstrate preparationSurfaces to be adhered or sealed should be free of dirt,oil and other contaminants. For best performancethe surface with a solvent such as isopropyl alcoholacetone or methyl ethyl ketonecloth.A surface primer is recommended for hard to bondsurfaces, such as some plastics. Apply a thin coat ofprimer after cleaning the surface with solvent, and allowdrying for 5 to 10 minutes at room temperature.Note that the adhesive may not showpolyethylene, polypropylene, polyacetal or Teflon.Method of applicationAdhesive/sealant can be applied directly from itscollapsible tube or extruded from its cartridge.A plastic nozzle is supplied which can bedesired orifice and shape to facilitate application.Apply a continuous bead of adhesive/sealant toprepared surface in a uniform thickness. If spreading isrequired, use enough pressure to spread theadhesive/sealant and displace any trapped airThe adhesive/sealant bead size to be specified is afunction of anticipated gap size for the part and theflange width. Consult Anabond representative forequipment supplier and design recommendations.Shelf lifeWhen stored at or below 300C, in the original unopenedcontainers, this product has a shelf life ofthe date of manufacture.PackingAdhesive/sealant is availablealuminium tube, 300ml HDPE cartridges.
