GE Silicones RTV5222 Neutral Cure, One Component RTV Adhesive Sealant

Subcategory: Silicone; Thermoset; Polymer

Close Analogs:

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

Material Notes:
RTV5220 series sealants are alkoxy neutral cure, one-component, ready to use silicone adhesive sealants exhibiting low modulus/high elongation that will maintain a strong bond even when exposed to extreme movement. RTV5220 series3 sealants are true neutral curing silicone sealants that release methyl alcohol during cure while exposed to atmospheric moisture at room temperature.

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.
