JIS A 6203:2015 PDF Download

JIS A 6203:2015 is a standard that provides guidelines for the use of polymer dispersions and redispersible polymer powders as cement modifiers. The purpose of this standard is to ensure the quality and performance of these additives when used in polymer-modified mortar or concrete applications.

Polymer dispersions are liquid materials that contain finely dispersed polymer particles. They are used to enhance the properties of cement-based materials, such as improving adhesion, flexibility, and water resistance. Redispersible polymer powders, on the other hand, are solid materials that consist of polymer particles that can be easily dispersed in water. These powders also contribute to the improvement of various properties of cement-based materials.

The standard sets out requirements for the composition, physical properties, and performance characteristics of both polymer dispersions and redispersible polymer powders. It specifies the criteria for determining the solid content, viscosity, pH value, minimum film formation temperature, and various mechanical properties of these additives.
