A comparison and guide to choosing Azichem glues: Osmokoll Mono, Osmokoll Bic, Unikoll and Sanakoll

Polymer-modified cement adhesives are essential for the success of any construction project. These materials must ensure a strong bond between elements of different nature. The products we offer are designed to provide maximum compatibility between various materials and to be resistant to water, heat, and aggressive substances, ensuring maximum durability of the bond created.

Azichem offers a range of products for bonding and protecting surfaces, each with unique characteristics and specific applications. In this article, we will explore the main differences and features of four products: Osmokoll Mono, Osmokoll Bic, Unikoll, and Sanakoll.

Osmokoll Mono: Waterproofing and Flexibility

Osmokoll Mono is a waterproofing, osmotic, single-component cement adhesive, classified as C2TES1. It is available in two versions: gray and white. It is formulated with hydraulic binders with low soluble salt content, adhesive resins, selected sands, and additives that enhance workability and adhesive performance. This combination allows for a highly deformable product along with reduced water permeability.

One of Osmokoll Mono's strengths is its excellent adhesion after thermal cycles, with values well above the limits of its category. Additionally, the zero vertical slip facilitates, speeds up, and provides absolute precision during installation operations.

It is ideal for bonding coatings on horizontal and vertical surfaces, both indoors and outdoors, including large-format tiles and pool coatings, thanks to its ability to adhere even to low-porosity materials.

Osmokoll Bic: Maximum Adhesion in a Two-Component Version

Osmokoll Bic is a two-component cement adhesive, also classified as C2TES1. Its formulation is similar to the mono version, but the presence of special polymers in component B allows for greater versatility and extraordinary adhesion values.

All adhesion values (after heat action, water immersion, freeze-thaw cycles), certified according to EN 12004 standards, are far above category limits. Osmokoll Bic is perfect for all types of coatings on horizontal and vertical surfaces, and it is the ideal adhesive for pool coatings and outdoor surfaces, even in aggressive environments, as its two-component structure provides maximum stability and resistance to external factors.

Unikoll: Versatility and Stability

Unikoll is a single-component cement adhesive, classified as C2TE, with zero vertical slip. Formulated with fine hydraulic binders and starch derivatives, it is designed to provide excellent adhesion even for large-format coatings.

It is ideal for bonding tiles, ceramics, gres, and natural stones, both indoors and outdoors. Its zero vertical slip property makes it particularly suitable for applications on vertical surfaces.

Sanakoll: Solution for Thermal Bridges and Damp Masonry

Sanakoll is a single-component adhesive-smoothing compound based on hydraulic lime and flexible polymers. It is designed for use on various substrates and offers surface leveling properties.
It is particularly useful for leveling applications and for treating thermal bridges, damp, and damaged masonry, thanks to its composition that promotes adhesion under critical conditions.

It is part of the SANAGEB bio-building line, which offers products made with components free from recognized or potential harmfulness, ensuring the best health during application and service life, without any issues related to end-of-life disposal.

Sanakoll, combined with our SANATEX membrane, forms our SANADRY system, a micro-coating that provides a solution to rising damp, mold, and condensation problems.

Comparison and Choices

Main Features:

• Osmokoll: Single-component, waterproof, flexible, zero vertical slip.
• Osmokoll Bic: Two-component, waterproof, flexible, maximum adhesion.
• Unikoll: Single-component, versatile, with zero vertical slip.
• Sanakoll: Single-component for the Sanadry System, ideal for thermal bridges and damp masonry, bio-building line.

Finally, we remind you that choosing the right product depends on specific installation needs, and it is always necessary to follow the guidelines indicated in UNI 11493 “Ceramic tiling on floors and walls. Instructions for design, installation, and maintenance.”
