Perfect Vision RTV 100% Silicone Rubber adhesive/sealant is a paste-like, one component material which cures to a tough, rubbery solid when exposed to moisture in the air. Since it will not flow of its own weight, this sealant can be applied overhead or on sidewall joints and surfaces without sagging, slumping or running off. It will adhere to clean metal, glass, most types of wood, silicone resins, vulcanized silicone rubber, ceramic, natural and synthetic fiber, as well as painted and many plastic surfaces.


The Perfect Vision RTV 100% Silicone Sealant  has good resistance to weathering, vibration, moisture, ozone and extreme temperatures. It may be applied in sub-zero weather without loss of extrusion or physical property characteristics. 



  • Sealing windows in oven doors and flues on gas appliances, flanged pipe joints and access doors
  • Adhering auto and appliance trim, including metal, fabric and fabric backed plastics
  • Sealing trailers, truck cabs
  • Filleting and caulking joints in sheet metal stacks, ductwork, and equipment housings
  • Bonding gaskets in heating and refrigeration units
  • Sealing of marine cabins and windows
  • Ant abrasion coating

  • Formed-in-place gasket for gear boxes, compressors, pumps




Applying the Material: Tack-Free Time


The Perfect Vision SG3 Silicone Sealant  is supplied ready-to-use. Under pressure it flows readily from its container. The paste-like consistency makes it easy to work; a spatula or wooden paddle can be used for tooling the surface. The cure progresses inward  rom the surface. At conditions of at least 75°F (24°C) and 50% relative humidity, the sealant forms a tack-free skin within 20 minutes. Tooling is not practical after this skin begins forming and should be completed within 5 to 10 minutes of application, even though this may require alternate periods of applying and tooling. Likewise, if masking tape has been used to mark off the area, it should be removed before the tack-free skin forms.


Cure Time

Cure time is affected by relative humidity, degree of confinement and cross-sectional thickness of the sealant.  Up to 1/8” thick become rubbery solids in about 24 hours at room temperature and 20 percent relative humidity. Less moisture content reduces it slightly. In 24 hours, sections up to 1/8” thick cure to a rubber with a Shore A durometer hardness rating of about 25 points. After 3 days at room temperature, this durometer hardness levels off to about 30 points.
