Silastic RTV silicone

Silastic RTV siliconeapplications Silastic RTV siliconewill reproduce the finest detail and are suitable for a variety of industrial and artrelated applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements. Silastic RTV siliconecanalso be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent) Operation Instructionof Silastic RTV silicone 1)Correctmixingratio ComponentAisSilastic RTV silicone,andcomponentBiscuringagentorvulcanizingagent,usuallythemixingratiowillbe2-3%.Suchasto100GSilastic RTV siliconeshouldbeadded2Gcatalystandthenmixthemtotally Note:theweightofthesiliconeandcatalystshouldbeweightedcorrectly.Accordingtolocalweather,themixingratiocanbe100to2underroom-temperature25 centi-degree;ifthelocalweatherisabout10 centi-degree,thenthemaximummixingratioshouldbe5%;Whenlocaltemperatureis-5centi-degree,noreactionwillhappenbetweenthesiliconeandhardener;oncethetemperatureoflocalweatheris38-45centi-degre,themixingratioofsiliconeandsiliconerubbershouldbe1%. 2)PreparationoftheOriginalmolds Firstly,youshoulddealcarefullywiththeOriginalmoldortheproductsyouwanttobemolded.IfnopolishingoftheOriginalmoldortheproductsyouwanttobemolded,thesurfaceoftheoriginalmoldorproductsisnotsosmoothorperfect,thentheproductsmadeoutofsiliconemoldswillbenotuptostandard. 3)Vacuum-PumpingProcess TomixtheSilastic RTV siliconeandcatalystwithastandardmixingratioandthendotheprocessofVacuum-Pumping.Bubbleswillcomeoutduringthemixingofthesiliconeandhardener,ifwithoutVacuum Pumping,thebubblescannotbereleasedfromthemixture,asaresult,therewillbemanybubblesinthefinishedsiliconemold.Thenthemoldhasalesstensilestrengthwhichwillaffectthereproductiontimes.Suchanunsmoothedsiliconemoldwillaffectthequalityoftheproductiondirectly. Frequently asked questions of Silastic RTV silicone Why isn’t thecasting molding silicon mold acid & alkali and aging resistant? It is due to the addition of the silicon oil. Normally we do not advise our customers to add any silicon oil into thecasting molding silicon rubber. If it is necessary, the ratio must be 5%-10%.
