Primary sealant

Primary sealant PIB 1000 - WinStyle

Primary sealant is the main sealant in a glass unit, the main function of which is to create a vapor barrier that provides the tightness, vapor and gas tightness of the glass unit.
As a primary sealing layer in glass units, both one-component and double-sided tapes are used. The one-component thermoplastic sealants are based on isobutene polymers, which are applied to the frame using an extruder. The double-sided tapes have various coatings – acrylic or modified rubber –are easy to use, do not require special equipment, but in terms of quality characteristics they are significantly inferior to sealants. Tapes coated with butyl rubber sealant have high quality characteristics, but their use increases the cost price.

WinStyle offers the following primary sealing products:
