Secondary sealant
Thiover is two-component polysulfide sealant of Thiokol series designed specially for application in the production of multiple glass panes. The sealant Thiover is manufactured in different packages depending on the method of its application (manual, with the use of equipment). The sealant Thiover does not contain the solvents and can be used for both single-stage and two-stage method of sealing.
