Key Performance Properties:

• A non-corrosive curing process that does not produce exothermic heat or corrosive by-products. Can be used on most corrosion-sensitive electrical and electronic equipment with no adverse effect
• Low modulus/high elongation sealant with primerless adhesion to most metals, painted surfaces and plastics, including polycarbonate and acrylic
• Compatible with most sensitive metals and plastics
• Withstands exposure to harsh environments such as chemical, ozone, moisture and weathering
• Good tear resistance
• Easy handling with no mixing, heating or solvent hazards
• Low odor cure by-product
• UL recognized component - file number E-36952
• Retain elastomeric properties at temperatures of -75° to 1400°F

Applications:

The RTV5220 series are low modulus/high elongation, alkoxy neutral one-part silicone sealants designed for use with glass, ceramic, metals, and plastics. RTV5220 sealants are well suited when bonding materials with large thermal coefficient of expansion properties, and dissimilar materials.

Because they are one-part products, there is no mixing required. The sealant can be easily dispensed from simple bulk dispensing pumps or cartridges. Base/catalyst ratio control, static mixer maintenance, butterfly testing for mix uniformity, yield loss from base purging, and other activities/costs associated with two-part sealants are eliminated.

GE Silicones became a part of Momentive Performance Materials in 2006.
