What is the cation exchange capacity (CEC) of Laponite®?
For Type1 products, Laponite® B, XL21, JS, CEC is typically 90 to 100 meq/100g. For Type 2 products Laponite® RD, XLG, RDS, S482, XLS, CEC is typically 50 to 60 meq/100g. 37. Is Laponite® compatible with cationic surfactants? Laponite® products are anionic materials and will normally co-flocculate with cationic surfactants. 38. Can I use Laponite® to make conductive/ antistatic paints? Laponite® particles are intrinsically conductive and the product is widely used to make conductive/ antistatic treatments on surfaces such as paper and polymer films. In order for Laponite® to be an effective conductivising agent it must be present as the main component in the coating formulation. A typical conductivising formulation would contain 100 parts Laponite® JS to 10 – 20 parts emulsion resin binder at a total solids content of ~20%. When such a coating is applied onto a surface and dried, it ensures maximum and intimate contact of Laponite® particles with each other. As a result of this, the fi
