- Primerless Adhesion on Most Common Construction Surfaces
- One-Part Grainy Textured Finish
CRL Vulkem® 116 Sealant is a one-part moisture curing, gun grade polyurethane sealant. Vulkem® 116 is durable, flexible, and offers excellent performance in moving joints. No primer is required on most construction materials, and it applies with conventional caulking guns.
Basic Uses
Vulkem® 116 is an excellent general purpose sealant designed for use in precast masonry, glazing, window frame perimeters, and similar types of construction joints. Suitable for continual immersion in water with the appropriate primer. Designed for exterior and interior use, the light, grainy texture has proven very popular for matching textured substrates like stucco and masonry, and for smooth metal storefront joints. The light texture blends and hides tooling marks, and the wavy effect that is inevitable when tooling sealants.
