METOLAT® 514

Salt of a polycarboxylic acid.

• Salts of polycarboxylic acids
• Dispersants for inorganic pigments and fillers
• Reduction of coating color viscosity
• Broadest compatibility
• Stabilization of pigment slurries

METOLAT 514 is an anionic dispersing agent with low foam tendencies suitable for many aqueous systems. It is recommended for most common pigments and fillers. METOLAT 514 is compatible with many emulsion polymers. It can be used over a wide pH range. METOLAT 514 reduces the mill base viscosity and provides higher pigment volume concentrations. It prevents the formation of settlements and stabilizes the system.

Ladder studies are recommended to determine optimum levels. Normal dosage ranges from 0.1 - 0.5 % METOLAT 514 on pigment and filler. It can be used alone or in combination with third dispersant technologies, e.g. polyphosphates (i.e. Calgon N) and tetra potassium pyrophosphates. Recommended mixtures of METOLAT 514 with polyphosphates are 1:2 to 2:1. Addition of more than 1% on total formulation may influence the water sensitivity of the paint film. It is recommended to dose METOLAT 514 before addition of pigments and extenders. Addition during production at a later time is possible.

METOLAT 514 is not sensitive to freezing. For better handling it should be stored between 5 and 25 °C. Aluminum containers are not suitable for the storage of METOLAT 514. The minimum shelf life in closed containers is 15 months from the date of manufacture.
