Product Overview

The RTV5242 12C is an one-component alkoxy neutral cure electronic grade Silicone Adhesive Sealant exhibiting high strength that will maintain a strong bond even when exposed to moist environments. RTV5240 series sealant is true neutral curing silicone sealants that release methyl alcohol during cure while exposed to atmospheric moisture at room temperature. Unlike most alkoxy curing silicone sealants, RTV5240 series cures very rapidly. 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. The RTV5240 series has demonstrated that it is able to maintain adhesion to many substrates after 20 weeks immersion in 60°C water.
  • Fast green strength build and fast cure (approximately 4x faster than traditional alkoxy sealants)
  • Low odour cure by-product
  • Tough and resilient sealant with primerless adhesion to most metals, painted surfaces and plastics
  • Excellent electrical insulation properties
  • Withstands exposure to harsh environments such as chemical, ozone, moisture and weathering
  • Compatible with sensitive metals and plastics
  • Good tear resistance
  • Easy handling with no mixing, heating or solvent hazards
  • Retains elastomeric properties at temperatures of -75 to 400°F
