Dow Corning® 896 PanelFix for Panel Bonding

DESCRIPTIONDow Corning 896 PanelFix forPanel Bonding is a one-part,neutral curing alkoxy siliconesealant specifically designed fornon-glass facade applications tostructurally bond two substratestogether. Neutral alkoxy siliconescure at room temperature onexposure to water vapor in the air,giving off a small amount ofalcohol (Methanol).GREEN STRENGTHDow Corning 896 PanelFix forPanel Bonding provides highdurability and immediate GreenStrength directly after application.Once applied and fully cured,Dow Corning 896 PanelFix forPanel Bonding is able to withstanddynamic and permanent loads.Please come back to ourDow Corning Technical ServiceExperts to calculate and define thecorrect joint dimension accordingto the final service life conditions.The property of instant GreenStrength can eliminate or decreasethe usage of tapes for pre-fixingdepending on the panel sizes. It istherefore able to enhanceproductivity, can save time andlabor cost. Dow Corning 896PanelFix for Panel Bondingprovide very good durability and issuperior to organic sealants due toits UV- and temperature resistance.The immediate Green Strength isabout 4-5 times higher thanstandard sealant which givesadditional safety during theproduction and assembly process.High humidity level and highertemperatures accelerate the cureprocess and lead to earlier skinformation.Green Strength is continuouslybuilding up during cure. Adhesionto the substrates is developed at thesame time as product cures.Although the strength build up isquite fast, the sealant will developits final properties once completelycured. It is recommended to installthe units only, once fully cured. Incase the units are installed beforecomplete cure, a suitable mountingaid such as specific tapes, may berequired. A further requisite for ahigh quality bonding applicationconsists in an appropriate jointdimension. Depending onparameters such as glass weight,window sizes, but also framematerials and temperatures, jointdimensions may vary. The jointthickness depends on the expectedmovement and the joint widthdepends on the applied dynamicand permanent loads. More specificinformation about bonding isavailable from our TechnicalService.. For each bonding projectseparately and depending oncustomer requirements,Dow Corning ConstructionIndustry Technical Service willprovide a tailor-made solution.For further information pleasecontact your local technical serviceengineer, who can help determiningthe required joint dimensions.COLORDow Corning 896 PanelFix forPanel Bonding is available inwhite color.HOW TO USEDow Corning 896 PanelFix forPanel Bonding is a ready to usesilicone sealant. It providesexcellent strength and adheres to awide range of most common PanelBonding materials such as mineralsubstrates, metal (anodizedaluminum, stainless steel, etc.) andglass.Dow Corning 896 PanelFix forPanel Bonding can be used formanual applications using a manualgun for cartridges or sausages. It isalso suitable for semi-or even fullyautomated robotized applications.Due to its low stringing , and HighGreen Strength, Dow Corning 896PanelFix for Panel Bondingprovides good ease of use,workability and a highercompressive strength in an uncuredstate.There is far less squeeze out asseen with standard sealants.As it is a moisture curing sealant,the reaction starts at the surfaceexposed to moisture and cures indepth. The deeper the joint is, thelonger it takes the sealant to curecompletely. The initial GreenStrength takes over initial loads,but to provide full strength andmovement capability with elasticrecovery it needs to be fully cured.Moisture has to migrate further tothe already cured skin and as thisskin becomes thicker, the reactionslows further down. Thecombination of initial GreenStrength overlapping with thestrength build up during curemakes the Dow Corning 896PanelFix for Panel Bondingsuperior versus standard one partand silicone sealants.As 1-part silicones need moistureto cure, the joint depth is limitedto 14-15 mm as a maximum.Joints deeper than that will notcompletely cure. The deeper thejoint is, the longer it takes to fullycure.CleaningSubstrates must be clean prior toapplication to ensure adhesiondurability. All surfaces must beclean from contaminants andresidues such as grease, oil, dust,water, frost, surface dirt, oldsealants or glazing compounds andprotective coatings. Solvent shouldbe wiped on and off with clean, oilandlint-free cloths. Metal, glassand plastic surfaces should becleaned by solvent procedures.Solvent should be wiped on and offwith clean, oil- and lint-free cloths.Dow Corning ® R40 Cleaner isrecommended for cleaning ofmetallic and glass surfaces.
