Butyl Sealant Frequently Asked Questions

What is Butyl Sealant?

Butyl sealant is a highly flexible synthetic rubber-based sealant that is widely used in the construction industry. It has excellent adhesion and weatherability and can effectively seal joints and gaps for glazing, roofing and sealing applications.

What are the key properties of Truemei butyl sealants?

Truemei butyl sealants have excellent moisture and air barrier properties, excellent flexibility, excellent adhesion to a wide range of substrates, aging and weathering resistance, and compatibility with other building materials.

What is the difference between butyl and silicone sealants?

While both butyl and silicone sealants are widely used in construction, they differ in their chemical composition and properties. Butyl sealants are solvent-based and cure by solvent evaporation, while silicone sealants are moisture-cured.

Can Butyl Sealants be painted?

Yes, butyl sealants can be painted after they are fully cured. It is recommended that a compatible latex or oil-based paint be used and that a compatibility test be performed prior to application. Proper surface preparation may be required to ensure good paint adhesion.

What are the applications for Truemei butyl sealants?

Truemei butyl sealants have a wide range of applications, including glazing systems (for sealing insulating glass units and window frames), roofing and waterproofing installations, sealing joints in precast concrete panels, and sealing gaps in metal buildings and curtain walls.

What are the typical cure times and application temperatures for butyl sealants?

Butyl sealants cure by solvent evaporation and cure times vary depending on temperature, humidity and joint configuration. Typically, they reach a non-stick state in 24-48 hours and are fully cured in 7-14 days. Truemei butyl sealants can withstand a wide range of operating temperatures, typically from -40°C to 80°C.
