Acronal 81 D Acrylic BASF Acrylics/ Acrylates ADHESIVE >> Water-based >> Pressure sensitive (PSA) SEALANT Acronal® 81 D is used in high-performance pressure-sensitive adhesives and construction adhesives for PVC and other floorcoverings where superior plasticizer resistance is required. Acronal® 81 D is used for dispersion-based pressure-sensitive adhesives provided that the adhesive is applied in amounts ranging from 20-80 g/m², depending on the end-use application. Another field of application is in the manufacture of dispersion-based sealants for connection joints and expansion of up to 15% Acronal® 81D exhibits self-thickening when neutralized to pH levels above approximately 7.5, resulting in potential thickener cost savings. We recommend adding a preservative to adhesives and sealants that contain Acronal® 81 D to protect them from microbial attack, particularly if their pH lies in the neutral range. The suitability of such additives must be verified and monitored in trials. Commercially available antifoams are suitable for suppressing foam. The amount required must be determined in trials, though usually 0.05-0.2%, expressed in terms of the adhesive, is sufficient. Acrylic based resin. Used in high-performance pressure-sensitive adhesives and construction adhesives for PVC and other floorcoverings where superior plasticizer resistance is required.
