Bostik not only provides PIB primary sealants, but has improved the technology to offer both curing and non-curing primary sealants. These offer improved gas retention and long-term durability. Curable primary sealants and non-curing primary sealants are specially formulated to compensate for the shortcomings of standard PIB.

Markets: 

EvoStik is specially formulated for use in the production of dual seal insulating glass units. It provides a true dual seal and was the first of its kind in the insulated glass market. EvoStik can be co-extruded with other curable technologies on linear extruders. It can also be used as a spacer bar adhesive.
