DA-1122

DA-1122 is a water-redispersible vinyl acetate/ethylene copolymer powder, easily dispersible in water and ideal for blending with inorganic binders such as cement, gypsum, or hydrated lime. It is particularly suitable for use in construction adhesives. This product is used in applications like mineral plasters, repair mortar, tile adhesive, and trowelling compound. Key features of This product include abrasion resistance, excellent adhesion, improved flexural strength, and enhanced workability.

    Application Information
    • DA-1122 improves adhesion, flexural strength, abrasion resistance and workability of modified compounds such as tile adhesives, repair mortars, mineral plasters and gypsum based compounds.
    • DA-1122 contains a fine, mineral filler as anti-blocking agent. It is free of solvents, plasticizers and film-forming aids.
    Application Information

    Tile adhesives:

    • For thin-bed tile adhesives with good frost resistance, we recommend using 1~5% DA-1122 and about 0.2 - 0.6 % of cellulose ether or other appropriate cellulose derivatives as water retention agent, and, if necessary, organic fibres to reduce slump.
    • Tile adhesives containing 3-6 % DA-1122 are also suitable for bonding tiles to tiles or, depending on formulation, of tiles to organic substrates, such as wood and wood products.
    • Repair mortars DA-1122 is particularly well suited for modifying repair mortars, especially concrete renovation mortars. DA-1122 improves the adhesion, flexural strength, abrasion resistance and workability.
    • We recommend adding 1 – 6 % redispersible powder.

    Mineral plasters:

    • DA-1122 added to cement and lime-cement finishing plasters improve their adhesion and flexibility. To achieve optimum results, between 1.0 and 6.0% DA-1122 based on the total weight should be added. In addition, 0.1 – 0.5 % cellulose ether or starch ether or a combination of the two should be incorporated.

    Gypsum based compounds:

    • The addition of DA-1122 to trowelling compounds and boards containing gypsum as binder increases flexural strength, impact resistance and adhesion.
    • To improve water retention, cellulose ether should be added.
    • DA-1122 is also extremely suited for use in the formulation of self-leveling compounds based on gypsum and anhydrite. The recommended amount is 1 – 6 %.

    Storage Condition
    • DA-1122 redispersible powder should be stored in cool and dry environment.
    • It preferably be used as soon as possible in summer.
    • Storage in high temperature and humidity conditions will increase the risk of caking.
    • Opened containers should be used as soon as possible, if not, should be resealed to prevent ingress of moisture from the air.
    • DA-1122 redispersible powder supplied in paper bags should not be stacked.
    • Prolonged heavy pressure may cause caking. Storage under pressure should also be avoided.
