Silicone adhesive comes in various forms, including traditional, high-temperature, RTV, and silicone rubber sealant. It is malleable without losing strength, making it popular in construction, manufacturing, automotive, and visual arts. It can be a two-part process or in one container. It is used for bonding, waterproofing, sealing, and caulking. It should be stored at room temperature and used within its expiration date.
Silicone adhesive is an adaptable form of heavy-duty glue that comes in several varieties, including traditional silicone adhesive, high-temperature silicone glue, room temperature curing (RTV) adhesive, and silicone rubber sealant. Even after curing, the silicone adhesive is malleable without losing strength or holding power. This flexibility has made it a popular choice in many different industries, including construction, manufacturing, automotive and visual arts.
The standard silicone adhesive comes in one of two varieties. One involves a two-part process that requires the user to mix both parts of the glue, the adhesive and the curing agent, together. This type of glue generally dries quickly and is quite thick, making it difficult to work with. There is also a variety of silicone adhesives available in one container, with both glue and curing agent already combined. Curing material begins to dry when it comes into contact with moisture in the air, so this variety of adhesive typically takes a little longer to dry, but is easier to apply.
A high-temperature silicone adhesive is a popular choice for those looking for a robust epoxy for use in an exceptionally hot environment. This form of silicone glue is used extensively in bonding automotive gaskets, waterproofing high voltage electrical equipment, and sealing heating and ventilation systems, including chimneys and ducts. High temperature silicone adhesive is manufactured with insulating properties and is able to withstand peak temperatures and extreme weather conditions.
RTV silicone adhesive begins to dry as soon as it comes in contact with air. It sets quickly at room temperature and can be used for a variety of purposes. It is a popular choice for use as a household glue and caulk, sealing holes or cracks in glass, metal, fabric, gaskets and vinyl.
Boat builders find silicone rubber sealant to be an effective way to waterproof a boat. The silicone rubber adhesive resists sudden changes in temperature and offers a watertight seal. It is commonly produced for both indoor and outdoor use, providing resistance to the elements and durability in the face of cracking and deterioration.
All silicone adhesives should be stored at proper room temperature per manufacturer specifications. The glue is most effective when used within the expiration date printed on the label, however, stored properly, it may last well beyond its shelf life. If you’re unsure about the effectiveness of an outdated product, be sure to test a small sample to confirm its flexibility and holding power. If curing takes an excessive amount of time, the product should not be used.
