Properties

PAT-ADD LE 1040 is a very efficient surface tension modifier, effective at very low concentrations. The product demonstrates excellent substrate wetting, thus avoiding the formation of craters, pinholes and poor substrate coverage of coatings applied onto critical substrates such as improperly cleaned substrates and low surface tension substrates. Moreover, PAT-ADD LE 1040 provides excellent surface smoothness, contributes to slip and mar resistance and counteracts pigment floating or foam formation. PAT-ADD LE 1040 is suitable for use in pigmented as well as clear coating systems.

Addition and Dosage

The optimal amount of PAT-ADD LE 1040 to be used is system and application related; in order to maintain proper recoatibility properties, excessive levels should be avoided. PATADD LE 1040 may be added to the formulation during any stage of paint production. The recommended dosage is between 0.05 to 1.0%, calculated on the total weight of the formulation. It is strongly recommended to evaluate performance and compatibility empirically, applying close-to-practice test conditions. The optimum concentration to be used depends on the individual requirements and conditions.
