DA-1450 is a water-redispersible vinyl acetate/ethylene copolymer powder, easily dispersible in water to create a stable emulsion. This soft and flexible resin, with a relatively high ethylene content, includes a fine mineral filler as an anti-blocking agent. is solvent-free, devoid of plasticizers, and requires no film-forming aids.

    Recommended Applications

    DA-1450 improves adhesion, flexural strength, plasticity, abrasion resistance and workability of modified compounds such as tile adhesives, thermal insulation systems, repair mortars and mineral plasters. It is therefore compatible with mortar additives used to achieve special processing characteristics. DA-1450 contains a fine, mineral filler as anti-blocking agent. It is free of solvents, plasticizers and film-forming aids.

    Recommended Uses

    Tile adhesives

    For thin-bed tile adhesives with good frost resistance and prolonged open time, we recommend using 1~5% DA-1450 and about 0.2 - 0.6 % of cellulose ether or other appropriate cellulose derivatives as water retention agent. DA-1450 prolonged its open time on construction adhesives. To obtain adhesives with greater plasticity, the proportion of redispersible powder should be increased, the amount of cement reduced.

    Thermal insulation systems

    To obtain adhesives with greater plasticity, it is advisable to use 3~6 % DA-1450 and 0.1 – 0.3 % of a suitable water retention agent such as cellulose ether. If the adhesives are required to bond sheets of extruded polystyrene foam, preliminary tests are essential.

    Repair mortars
    DA-1450 is suited for modifying repair mortars, especially concrete renovation mortars. DA-1450 improves their adhesion and flexibility. To achieve optimum results, between 1.0 and 6.0% DA-1450 based on the total weight should be added.

    Mineral plasters

    DA-1450 added to cement and lime-cement finishing plasters improved their adhesion and flexibility. Freshly prepared compounds modified with DA-1450 exhibit excellent non-slump behavior. To achieve optimum results, between 1.0 and 6.0% DA-1450 based on the total weight should be added.

    Processing Information

    For the production of powdered products such as dry mortars, tile adhesives, troweling compound. DA-1450 redispersible powder is mixed with the dry, finely divided additives in suitable mixers. Pressure or excessive shear in the mixer and the transferring line should be avoided, since this will raise the temperature, leading to agglomeration of the thermoplastic resin particles. After sufficient water has been added, mortars or trowelling compounds can be mixed by hand or machine. Since mixing by hand only generates low shear forces, it is best to allow the mixture to mature by leaving it to stand for 5 minutes, and then to stir it again.

    Storage & Handling

    Storage Information

    DA-1450 redispersible powder should be stored in cool and dry environment. It is recommended to use within 6 months, 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-1450 redispersible powder supplied in paper bags should not be stacked. Prolonged heavy pressure may cause caking. Storage under pressure should also be avoided.
