Leveling test procedure ASTM D4062. What it is and how to use it?

Water-soluble paints based on winyl-acrylic, styrene-acrylic or pure acrylic emulsions contain thickeners in their formulations ensuring appropriate rheological properties at low, medium and high shear rates. Setting the ideal viscosity to ensure no sagging, Stormer-viscosity and ICI-viscosity requires a balancing of different rheological additives and dosages. Often, with selected rheological properties allowing for good application, no…

Formulating of latex paints using the relationship between PVC and CPVC

The formulation of latex paints, as well as paints in general, requires extensive knowledge of the basics of the raw material composition of paints, the raw material base and the amounts of use of individual raw materials. While the number of recommended dosages can be determined at the beginning from the doses oscillating in the ranges…

Effectiveness of thickeners in preventing sagging

Latex paint formulations for architectural applications are intended for the manufacture of DIY paints and for applications by professional painters who apply them with a brush, paint rollers and various spraying techniques. During their application, most substrates are placed on vertical surfaces, such as walls, furniture fronts or fences. Application to such surfaces carries the risk…

Development of hardness of acrylic WB paints by coalescing agents

The hardness parameter is usually associated with floor paints, parquet varnishes and other coatings that require high resistance to deformation under the pressure exerted on them by harder objects. However, hardness as a strength parameter also applies to coatings in other applications and is an indicator of how the coating acquires its parameters, and the development…

How to use start point formulations of architectural latex paints

Start point formulations is an inseparable document supplied with raw material samples and other technical materials, which allows both newcomers and the more experienced formulators to see how a given raw material can be used. Of course, it is good if the start point formulation in addition to the list of raw materials and their quantity…

Chemical resistance of decorative wood and architectural water-borne coatings

Chemical resistance is commonly associated with industrial coatings for tanks, floors onto which oil or gasoline may spill, or other places that are exposed to constant or intermittent contact with chemicals. With regard to waterborne decorative wall paints or wood coatings, chemical resistance is generally not expected, not to say that a certain group of chemicals…

Increasing sheen and gloss of latex paint coatings by wet rubbing

The requirement to easily remove stains from latex wall paints is nowadays an increasingly common standard in paint formulations not only of the premium class, but also of the higher-end random paints. Raw materials such as polymer dispersion, thickeners, surfactants, specially added additives, fillers, pigment volume concentration, etc., are responsible for the easy removal of stains.…
