How to use ATMP in coatings

Using Amino Trimethylene Phosphonic Acid (ATMP) in coatings is a specific and effective application to solve stability issues. Here is a comprehensive guide on how to use it correctly.

Primary Function of ATMP in Coatings

ATMP acts primarily as a dispersion stabilizer and anti-settling agent. Its main job is to prevent inorganic fillers and pigments (like calcium carbonate, kaolin, titanium dioxide) from forming hard, irreversible sediment at the bottom of the container during storage.

Step-by-Step Guide to Using ATMP

1. Dosage and Formulation

Typical Dosage: The effective dosage range is quite low, typically between 0.1% to 0.5% of the total weight of the coating formulation.

Start Low: It is crucial to begin with a lower dosage (e.g., 0.1%) and conduct stability tests. Overdosing can sometimes lead to viscosity changes or other unforeseen interactions.

Compatibility Check: Before full-scale production, always perform a lab-scale compatibility test to ensure ATMP does not cause flocculation, gelling, or loss of opacity with your specific resin and other additives.
