VULKEM 116 10OZ

Vulkem is durable and flexible and offers excellent performance in dynamic joints and is an excellent choice for sealing expansion joints in commercial construction use. Vulkem 116 is also suitable for certain water immersion uses and is rated for 25% movement capability  

Vulkem 116 is an excellent general-purpose sealant designed for use on poured and precast concrete, masonry work, window and door perimeters, and similar types of construction joints. 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. Do not apply Vulkem 116 over damp, green, or contaminated surfaces. It may be used in any vertical or horizontal joint designed by accepted architectural/engineering practices. Joint width should be 4 times the anticipated movement but not less than 1/4 inch.

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 use. Vulkem 116 is also suitable for certain water  immersion use and is rated for 25% movement capability. The cure of the sealant can be accelerated with the  addition of the Vulkem Catalyst 45/116.  

• Service Temperature Range: -40° F to 185° F (-40° C to 85° C)
• It is also recommended that the sealant be stored at room temperature before applying it        
• Maximum Installation Temperature: less than 150° F (66° C) at the time the sealant is applied
• Minimum Installation Temperature: 40° F (4° C) and rising or above at the time the sealant is applied
• Average Cure Rate: Curing of polyurethane sealants occurs at approximately 1/16” (1.66mm) depth per day at 75° F (24° C) and 50% RH. The cure time will increase as the temperature and/or humidity decreases. A good rule of thumb is an additional 24 hours of a cure for every 10° F (-12° C) decrease in temperature.

Polyurethane sealant can be removed from the substrate or clothing by physically removing excess sealant by wiping, scraping, or cutting.   Residual traces of sealant can be removed by wiping the surface with a cloth or abrasive pad saturated with a solvent such as mineral spirits or xylene. Test a hidden area of the surface to be cleaned to ensure no adverse effects due to solvent interaction. Where abrasive pads are used, care should be exercised to ensure the surface appearance is not adversely affected.
