In this article, we will explore what Vulkem 116 is, its properties, and the different applications it is commonly used for. So, let's dive in and discover the world of Vulkem 116 polyurethane sealant.

Introduction to Vulkem 116 Polyurethane Sealant

Vulkem 116 is a premium-quality, one-component polyurethane sealant manufactured by Tremco. It is specifically formulated to provide exceptional adhesion and long-lasting protection against water, moisture, and other damaging factors. The sealant undergoes a curing process when exposed to atmospheric moisture, transforming into a tough and flexible material that can withstand extreme weather conditions.

Substrate Compatibility: Ideal for Diverse Materials

Vulkem 116 is renowned for its wide range of substrate compatibility, making it a go-to choice for multiple applications. The sealant adheres excellently to concrete, masonry, metals, wood, glass, and certain plastics. This versatility is an essential characteristic as it allows for consistent and reliable sealing across different substrates.

Sealing Joints and Gaps: Ensuring a Weatherproof Barrier

One of the primary uses of Vulkem 116 polyurethane sealant is to create watertight and airtight seals in construction and industrial settings. The sealant is commonly employed to seal joints and gaps in various structures, ranging from buildings and bridges to tanks and parking decks. Vulkem 116 provides a strong and durable bond, reducing the risk of water infiltration and ensuring long-term protection against leaks and air penetration.

Waterproofing Concrete and Masonry: Enhanced Durability

In the construction industry, waterproofing is a critical step in maintaining the longevity and structural integrity of concrete and masonry structures. Vulkem 116 sealant acts as a protective layer, preventing water penetration and reducing the risk of moisture-related damage such as cracking and spalling. By applying the sealant to vulnerable areas, such as expansion joints and gaps between different building elements, contractors can significantly enhance the durability of the structure.

Expansion Joints: Accommodating Movement and Thermal Changes

Buildings and structures are subject to movement caused by factors such as temperature fluctuations, settling, and seismic activity. Expansion joints play a crucial role in allowing controlled movement and relieving stress, preventing structural damage. Vulkem 116 polyurethane sealant is extensively used in sealing and protecting expansion joints, ensuring they remain flexible and functional. The sealant's elasticity enables it to accommodate movements caused by thermal expansion and contraction, thereby maintaining the joint's effectiveness and preventing leaks.

Traffic Deck Coating: High Performance and Slip Resistance

Vulkem 116 is commonly employed in traffic deck coating applications where heavy foot traffic or vehicular movement is expected. The sealant provides excellent adhesion and durability when used as a topcoat or a waterproof membrane. Moreover, Vulkem 116 exhibits a high coefficient of friction, resulting in slip-resistant surfaces. This quality is especially crucial in areas prone to wet conditions, such as parking structures and pedestrian walkways, ensuring safety for all users.


Vulkem 116 polyurethane sealant is a reliable and versatile product that finds its applications across various industries. With its superior adhesion, flexibility, and durability, Vulkem 116 offers exceptional protection against water infiltration, weathering, and structural damage. Whether it's sealing joints, waterproofing structures, or coating traffic decks, this polyurethane sealant has proven its effectiveness time and time again. When it comes to ensuring long-term stability and reducing maintenance costs, Vulkem 116 is a go-to choice for professionals looking for a high-performance sealant solution.
