Why Is Butyl Sealant Not Sticking? Common Causes and How to Fix Them

Butyl sealant is known for its excellent adhesion and sealing properties. However, in practice, there are situations where it does not adhere properly, detaches from the surface, or fails to provide the expected sealing performance. In most cases, the issue is not related to the material quality, but rather to

Butyl Compounds in Sealing and Vibration Isolation of Railway Cars

Butyl compounds are one of the key materials used in modern railway rolling stock. Thanks to exceptionally low gas permeability, high resistance to ageing, and very good vibration damping properties, butyl rubber (IIR) is widely used in railcar sealing systems, acoustic insulation, and vibration isolation systems in rail vehicles. Products

Precast Concrete Fabrication: How to Ensure Long-Term Joint Tightness with Butyl Technology?

Modern precast concrete fabrication is synonymous with speed and precision. However, even the most accurately manufactured reinforced concrete element is only as good as its weakest point — the installation joint. It is precisely at the connections between elements that the greatest number of failures occur, related to water infiltration,

Building Airtightness (Blower Door Test) and Butyl-Based Products

Why Has Airtightness Become a Key Quality Parameter? Modern energy-efficient and passive construction requires not only high thermal insulation performance, but above all control of uncontrolled air infiltration. Air leakage through building envelope assemblies leads to energy losses, interstitial condensation, reduced occupant comfort, and an increased risk of mold growth.
