Vulkem 116 Polyurethane Sealant

Vulkem 116 is a one-part, moisture-curing, gun-grade polyurethane sealant.

It is durable, flexible, and offers excellent performance in dynamic joints.

Vulkem 116 has a 30-year history of delivering superior primerless adhesion to porous substrates, which makes it the choice for sealing expansion joints in commercial construction applications. Vulkem 116 is also suitable for certain water immersion applications and is rated for 25% movement capability. The cure of the sealant can be accelerated with the addition of the Vulkem Catalyst 45/116.

    • General-purpose sealant for use on poured and precast concrete, masonry work.
    • For use on vertical or horizontal joints. 
    Coverage Rates: 308 linear feet of joint per gallon for a 1/4 in. x 1/4 in. (6mm x 6mm) joint.

    Cure Time: Vulkem 116 generally cures at a rate of 1/16 in. (2mm) per day at 75ºF (24ºC) and 50% relative humidity. It will skin in 5 hours and be tack free in 30 hours. The cure time will increase as temperatures and/or humidity decrease. A good rule of thumb is one additional day for every 10ºF decrease in temperature.
    Clean Up:     Excess sealant and smears adjacent to the joint interface can be carefully removed with xylene or mineral spirits before the sealant cures. Any utensils used for tooling can also be cleaned with xylene or mineral spirits.
    Limitations:     Do not apply Vulkem 116 over damp or contaminated surfaces. Vulkem 116 is approved for exterior use only. Do not use this product inside an occupied building even if there are no occupants present during use.
