Momentive RTV5249 is a grey paste sealant with an alkoxy neutral cure, one-component, ready to use, electronic grade silicone adhesive sealant exhibiting high strength that will maintain a strong bond even when exposed to moist environments. RTV 5249 is a true neutral curing silicone sealant that releases methyl alcohol during cure while exposed to atmospheric moisture at room temperature. Unlike most alkoxy curing silicone sealants, Momentive RTV5249 cures very rapidly. RTV5249 offers a non-corrosive curing process that does not produce exothermic heat or corrosive by-products can be used on corrosion-sensitive electrical and electronic equipment with no adverse effect, it offers a fast green strength build, fast cure (approximately 4x faster than traditional alkoxy sealants) and is a low odour cure by-product. RTV5249 is a tough and resilient sealant with primerless adhesion to most metals, painted surfaces and plastics and is a UL recognized component, File number E-36952. Momentive RTV5249 has superior hydrolytic stability and has demonstrated that it is able to maintain adhesion to many substrates after 20 weeks immersion in 60°C water. RTV5249 offers excellent electrical insulation properties whilst eithstands exposure to harsh environments such as chemical, ozone, moisture and weathering and is compatible with sensitive metals and plastics. RTV5249 boasts good tear resistance and easy handling with no mixing, heating or solvent hazards. It can retain its elastomeric properties at temperatures of -75 to +400ºF.
