Tremco JS334
JS334 is a solvent-free, one-component, hotmelt butyl-based sealant specially developed for the manufacture of insulated glass units. JS334 functions as the outer barrier or secondary seal in either single or dual-seal systems. JS334 can be used in conjunction with a PIB primary sealant such as JS680 for dual-sealed units.
Packaging: 6.5kg carton
Colour: Black
JS334 is designed to seal the perimeter of the insulated glass unit, retaining the structural bond between the panes of glass and spacer and forming an outer barrier to moisture and gas. JS334 is compatible with all types of manual and robotic dispensing equipment and can be applied with a hotmelt machine such as HM1500 EX.
