Technical Data Sheet
Aqueous Styrene acrylate polymer dispersion used to manufacture all types of adhesives, primers,
liquid membranes and textured finishes
Chemical Nature: Aqueous dispersion of an acrylic ester-styrene copolymer
DEXICRYL 492D is used to manufacturer building adhesives such as tile adhesives in paste form and panel adhesives, etc. The high binding powers of DEXICRYL 492D also allow it to be used to formulate primers, liquid membranes, textured finishes and sealants.
Formulations that contain pigments and fillers have to contain dispersing agents such as DEXICRYL D 034 in sufficient quantities to ensure that they remain stable in storage. More detailed information is given in our technical information leaflet on “DEXICRYL 492D and dispersing agents.”
The minimum film-forming temperature of DEXICRYL 492D can be lowered by adding a coalescent solvent in the required quantity. Further information is given in our technical information leaflet on “DEXICRYL 492D and film – forming agents”
Cellulose ethers and polyacrylates can be used to adjust the viscosity. Commercial deformers can be used to suppress
foam. It is usually sufficient to ass 0.05 – 0.2%, expressed as a proportion of the adhesive. The exact amount of defoamer has to determine in trials.
We would recommend adding preservatives to adhesives and sealants that contain DEXICRYL 492D to protect them from microbial attack over long periods in storage. The compatibility and efficacy of preservatives must be tested in trials.
