Vulkem 116 Gray Polyurethane Sealant – 10.1 Oz, Exterior Moisture-curing Gun-grade Sealant

Discover the bold Vulkem 116 polyurethane sealant for exterior joints: a single-component, moisture-curing formulation designed for gun-grade application. This durable, sealant excels in dynamic joints and is ideal for concrete, masonry, and around window and door openings. It features long-standing primerless adhesion to porous substrates, delivering reliable bonding without extra priming. This exterior-use sealant tolerates outdoor moisture and accommodates joint movement up to 25 percent.

How It Helps You: This exterior sealant provides strong, weather resistant sealing that helps prevent air and water intrusion while accommodating structural movement for longer service life.

• Primerless adhesion for porous substrates such as concrete and masonry improves bond strength and reduces surface prep, making it an efficient concrete sealant solution.
• Moisture-curing, one-component polyurethane chemistry delivers reliable, gun-grade performance for exterior joints without mixing.
• Exceptional flexibility with movement capability up to 25 percent, ideal for expansion joints and dynamic concrete joints in exterior constructions.
• Suitable for certain water immersion applications under approved conditions, expanding use in exterior settings where wet exposure occurs.
• Gray 10.1 oz cartridge format matches architectural finishes and provides convenient application for exterior projects.

Why This Product Stands Out: Choose Vulkem 116 for a proven, long-lasting exterior sealant that resists weather, movement, and moisture. Its primerless adhesion to porous substrates, tough polyurethane chemistry, and suitability for concrete, masonry, and window or door perimeters make it a reliable choice for commercial construction. Trust this gray cartridge to deliver durable seals, simplify installation, and extend the life of exterior joints.
