Description
FENZI Butyl Primary Sealant is the ideal solution for internal insulation in insulated glass units, acting as the primary vapor and gas barrier. The product is based on high-quality polyisobutylene (PIB) and supplied as a one-component, totally solvent-free sealant. It is engineered to provide minimal permeability to water vapor and gases, high resistance to ageing, and excellent adhesion to glass and metal spacer systems. The sealant can be safely used in combination with FENZI Thiover Polysulphide and other conventional secondary sealants, ensuring reliable long-term IG unit performance.
Spec & Technical Data
The PIB-based formulation ensures stable sealing performance with very low vapor and gas permeability, supporting the integrity of insulated glass units over time. The solid slug form allows consistent application on IG production lines, while compatibility with polysulphide and other secondary sealants makes it suitable for standard double-sealing systems. Designed for professional IGU manufacturing, the sealant delivers durability, reliability, and premium quality performance.
