Composition and Key Features of Sika 122

Sika 122 is a single-component, moisture-curing adhesive and sealant based on polyurethane. As a polyurethane-based product, Sika 122 combines several essential features that contribute to its overall effectiveness and performance:

1. High Adhesion Strength: Sika 122 is known for its superior bonding strength, allowing it to adhere strongly to a variety of substrates, including metals, concrete, plastics, wood, glass, and ceramics. The high initial tack and final bond strength make it ideal for applications requiring strong, reliable adhesion.
2. Flexibility: Unlike some rigid adhesives, Sika 122 maintains flexibility after curing. This is especially important in applications where there may be movement or thermal expansion and contraction. The ability to accommodate these changes without cracking or losing its bond is a significant advantage.
3. Durability: The product is highly resistant to aging, UV radiation, moisture, and temperature variations, which makes it ideal for outdoor and harsh environmental conditions. Whether it’s exposed to sunlight, rain, or extreme temperatures, Sika 122 continues to perform effectively, making it a trusted solution in many industrial sectors.
4. Weather and Water Resistance: Sika 122 offers excellent resistance to water and weathering, ensuring that the bond remains intact even in challenging weather conditions. This makes it an ideal choice for sealing applications exposed to the elements, such as automotive, marine, and construction projects.
5. Non-Sagging: Once applied, Sika 122 stays in place and does not sag, making it suitable for vertical and overhead applications. This is a valuable property for ensuring a clean and effective application, particularly in areas where gravity may cause the product to shift if it were not properly formulated.
6. Easy Application: Sika 122 is designed for easy application, whether using a manual or pneumatic gun. It comes in various sizes, including cartridges and sausages, to suit different project requirements. The product’s consistency makes it easy to smooth out and form the desired seal or bond.
7. Environmental Compatibility: As a solvent-free product, Sika 122 is environmentally friendly, emitting fewer volatile organic compounds (VOCs) compared to solvent-based alternatives. This is an important consideration in industries that require adherence to strict environmental regulations.
