Sikaflex 221 polyurethane - 300 ml, black

Sikaflex 221 is a high-quality one-component polyurethane adhesive and sealant, which is distinguished by its versatility and reliability. The product hardens under the influence of moisture from the air and forms an elastomer with high resistance to aging and weathering. Thanks to its elasticity and resistance, it provides a durable and secure sealing or bonding even under higher loads. The sealant has a low odor and is easy to work with, which makes it suitable for professional applications. After hardening, Sikaflex 221 can be sanded and painted, which further facilitates finishing activities and provides an aesthetic result. It is compatible with various painting and processing systems, which allows its wide application in construction and industry.

The product shows excellent adhesion to various types of surfaces without the need for pre-treatment in most cases. It is suitable for metal, metal primers and paints for metal coatings, ceramic tiles and plastic. This makes Sikaflex 221 a reliable solution for bonding and sealing a variety of elements in construction and industrial environments. Thanks to its resistance to aging and permanent elasticity after hardening, the product is suitable for use in applications where materials are exposed to vibrations, movements or temperature changes. This makes it the preferred choice for sealing connection joints, assembly work and bonding elements where reliability over time is required.
