Applications & Uses+
Additol XL 123 N prevents the formation of stable foam during manufacture and during application of the coatings. Defoaming is better in polar systems than in non-polar systems. No direct influence on intercoat adhesion and recoatabilitiy is observed when the recommended amounts of additive are used.
Additol XL 123 N is particularly effective in two-component polyurethane-coatings based on acrylate and alkyd resins and in stoving alkyd/melamine systems. It is effective in preventing foam formation in critical coating applications such as dipping, curtain coating and airless spraying.
Additol XL 123 N serves as additive in solventborne coating systems to increase slip, crack and scratch resistance and to improve flow. Further advantages are the foam breaking effect (without influence on recoatability) and the prevention of pigment flooding.
Technical Details & Test Data+
Additol XL 123 N can be added to the ready-to-apply paint. For fully effective defoaming it is advantageous to add Additol XL 123 N right at the beginning of paint manufacture.
The recommended amounts for use range between 0.05 - 0.5 % Additol XL 123 N, calculated on total paint. On account of the large number of possible formulations, the optimum activity should be determined in preliminary trials
