BUTYL
Butylver Standard is a premium PIB-based primary sealant designed for high-quality insulating glass units, providing an effective first barrier against moisture ingress and gas loss.


Made from polyisobutylene, Butylver Standard is a single-component, solvent-free sealant used to seal spacer edges in insulating glass systems. It offers strong adhesion to glass and spacers, excellent resistance to water vapor and gases, superior UV resistance, and long-term color stability. With zero shrinkage, high shear resistance, and very low thermal conductivity, it helps maintain the structural integrity, energy efficiency, and clean appearance of insulating glass units during handling and long-term use. Butylver Standard also holds CEKAL certification and complies with international quality standards.
