VINAVIL ®TECHNICAL DATA SHEETCRILAT 243004WD001 - 12/09P 1 - 2CRILAT 2430 is a solvent free, water based vinyl-acrylic pressure sensitive adhesive. A goodbalance of internal cohesion and adhesion characterizes the adhesive film. The dispersion has avery good mechanical and chemical stability, even at higher temperatures. The adhesive is notimmediately tacky when applied; this allows its use as a repositionable tape or label in someapplications.1.

Thepseudoplasticity of the dispersion suggests not to use it in gravure coating, unless properlydiluted or if a rough surface ot the coating is needed.To clean surfaces from wet adhesive, it is suggested first to wash with water and then, if needed,with polar solvents.To clean from dry adhesive, the use of MEK, acetone, ethyl acetate is suggested.Adhesion propertiesThe measurements are made by coating a PETP film, thickness 23 m, with 18 -20 g/m2 dryadhesive.Data, information and suggestions are provided for guidance purpose only.
