DIPICRYL 490D

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
Application
DIPICRYL 490 D is used to manufacture building adhesives such as tile adhesives in paste form and panel adhesives, etc. The high binding power of DIPICRYL 490 D 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 DIPICRYL D 304 in sufficient quantities to ensure that they remain stable in storage. More detailed information is given in our technical information leaflet on“DIPICRYL 490 D and dispersing agents.”
 
The minimum film-forming temperature of DIPICRYL 490 D can be lowered by adding a coalescent solvent in the required quantity. Further information is given in our technical information leaflet on“DIPICRYL 490 D 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 DIPICRYL 490 D to protect them from microbial attack over long periods in storage. The compatibility and efficacy of preservatives must be tested in trials.
