Reactive UV-Absorber combined with a Hindered Amine Light stabilizer for air-drying coatings especially for alkyd systems. ADD-7730 is developed on paint chemistry and transforms the ultra violet component of the daylight (300 – 400 nm) into harmless heat, thus eliminating the destructive action of UV-light and also provides significantly extended life time to coatings by minimizing paint defects such as cracking and loss of gloss. ADD-7730 contains a reactive group that cross-links with the alkyd-resins structure during the oxidative drying.

Storage, safety & handling
Should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 5 years from the date of manufacture. The expiry date is indicated on the container. The haziness and crystallization, which can take place upon storage at low temperature, has no influence on the quality of the product and can be reversed by heating.

coating systems. Especially suited for the dispersion of inorganic pigments.ADD-A40 can be used as supplied. The neutralizing alkali used in conjunction with the acrylic polymer can significantly impact the properties of the final coating. ADD-A40 releases ammonia during the drying process and therefore has little impact on water and alkaline resistance of the dry film. Use of ADD-A40 should be limited to pH 5 -10.5 and temperatures lower than 70°C due to potential loss of volatile ammonia.
