Polyurethanes offer a much higher tensile and shear strength than silicone sealants, making them ideal for heavy-duty projects like installing and repairing window frames, garage framing, roofing and sill plates. They are also resistant to corrosion and abrasions. These adhesives are also ideal for sealing cracks in walls and floors and repairing leaks in water fixtures, faucets, toilets and more.

When choosing the right construction adhesive, make sure to follow the manufacturer’s instructions for preparation and application. Different surfaces require different methods for getting them ready for the adhesive, including removing dirt and dust from concrete, scrubbing rust off of metal, and removing old caulking or glue from the surface. Once you have the surfaces clean, apply a smoothing agent to help get a uniform appearance.

Moisture Resistance

The moisture resistance of polyurethane adhesive sealants varies by formulation. Generally, these systems can withstand moisture well and are applicable in challenging environments and tricky locations where the substrates may be exposed to water or atmospheric humidity. This allows the adhesive to work effectively without damaging the substrates or allowing the bond to fail.

These construction adhesives can be used for bonding a wide variety of materials such as concrete, wood, plastics, galvanized steel and coated metal. They can also be used for sealing construction expansion joints. They are able to withstand a wide range of temperatures and have good elasticity.

One-component, moisture-curing PU is often used for door trim, instrumental panels and bonding steel frames to side glass windshields in transportation. Liquid, one-component PU has a fast tack and skin time and can be painted to improve the appearance of the final bond. This type of construction adhesive is available in cartridges, sausage packs and bulk formats to meet different needs and applications.

One-component, low modulus PU is a highly insulating and gap filling adhesive that can provide a flexible seal for construction joints. This enables them to withstand up to 50% movement without failing and also keep water and air out of the joint. These are commonly used for sealing a wide variety of construction materials including cement-based materials, brick, ceramic and glass, masonry and galvanized sheet metal. Rigid heat curing PU is another option for construction applications as it can be processed faster than its moisture curing alternative and forms stronger bonds.

UV Resistance

Unlike silicone sealants, polyurethane construction adhesive sealants are color stable, do not chalk or yellow and offer superior UV resistance. They are also durable and flexible, meaning they can withstand expansion and contraction due to weather changes. They do not drip or sag, and they are resistant to water, moisture, chemicals, salts and other contaminates.

Chemical Resistance

Polyurethane construction adhesive sealant is highly resistant to a variety of chemicals including hydrochloric acid, salt water, potassium hydroxide and many more. It can also withstand a wide range of temperatures and atmospheric hydrocarbons and is non-toxic to humans and animals.

Akfix offers a wide range of one-component and two-component liquid polyurethane adhesives that provide strong bonding and gap sealing for a wide variety of applications. These include construction, automotive, and industrial projects. Some of these products feature a wide operating temperature range and can be used with both metals and plastics. In addition, the adhesives are available in different viscosities for a choice of application thicknesses. There are even options that can be used as a caulking agent, or to fill small gaps and holes.

These adhesives can be applied to almost any surface and provide a high level of stress recovery polyurethane construction adhesive sealant to resist being bent or pulled. They also offer a quick curing time and can be painted to match the surrounding surface. They can be diluted with water to increase their viscosity for easier application and can even be applied to non-primed concrete.

Another advantage of these polyurethane construction adhesives is their excellent UV resistance. The reason for this is that polyurethane is an organic material and, unlike silicone, it does not deteriorate under UV exposure. This means that it can be used in outdoor applications without the risk of a loss of performance or strength over time. This can be particularly useful in the aviation industry, where the aircraft is exposed to extreme temperature changes from summer heat on the ground to below-freezing conditions at cruising altitudes.
