Who are perfectly designed for the use additives in Cement Tile Adhesive?

Landercoll® with Accurate®

Tile Adhesive

Brief Introduction

Cement Tile adhesives (CTA) are used to install tiles in residential and commercial buildings on floors or on walls.
Depending on the local construction technology, regional needs and building traditions, the choice of raw material, critical performance criteria as well as norms and regulations for testing adhesives can differ from country to country.
Depending on the requirements cementitious tile adhesives are either classified as C1 to achieve minimum values of 0.5N/mm² or as C2 with adhesion strengths of at least 1.0N/mm² respectively.

High performance and excellent working efficiencies

Landercoll® hydroxypropyl methylcellulose (HPMC K200) and Landercoll® Hydroxyethyl methylcellulose (HEMC EM200) are used in tile adhesives as a thickening and water retention additive.

Both types of additives control fresh mortar properties, rheology, and application performance as well as the final strengths of tile adhesives and grouts respectively.

Landercoll® promises high performance and excellent working efficiencies for the attachment of tiles to various substrates. Being slip-resistant and having better open time is the key to better adhesive requirements.

High bonding strength on different substrates

Accurate®VAE Re-dispersible Polymer Powder (4012N and 5011N) are used to improve deformability and high bonding strength on different substrates also under critical conditions.

It offers a number of benefits to the wet and dry-mortar properties of tile adhesives. When the dry-mix mortar is mixed with the required amount of water, the Accurate® VAE Re-dispersible Polymer Powder is completely in the aqueous phase. This is the precondition for a homogeneous film formation of the polymer during the subsequent setting of the mortar. In addition to the cement matrix the polymer matrix contributes to the bonding and compressive strength of the mortar.

Accurate® VAE Re-dispersible Polymer Powders are required in tile adhesive applications where – especially on different substrates – adhesion strength needs to be improved or special technical requirements (e.g. heat conditioning) have to be fulfilled. They also impart high flexibility or impact resistance and improved abrasion resistance once the mortar has hardened. Additionally, some tile adhesive formulations contain special performance Accurate® VAE Re-dispersible Polymer Powder which improve either the water repellency characteristics or the free flowing abilities of the mortar.
