MAT70 - Butyl primary sealant
MAT70 is one-component, solvent free thermoplastic insulating glass sealant based on polyisobutylen which does not harden. Exposure to heat results in significant softening. The maximum final strength is only achieved after processing on a press. This results in physical adhesion. Very tight to water vapour, argon and sulphur hexaflourid. Adheres to all surfaces commonly used in the insulated glass industry such as glass, aluminium, zinc or stainless steel. MAT70 is used as a primary sealant in combination with a secondary sealant such as MAT77, HotMAT or any other sealants used in the manufacturing of insulated glass.
