BASF Melagard MC is a world-renowned high-quality UV absorber with excellent performance and is widely used in polymer materials such as plastics and coatings. As for the dosage of its added preparations, it is necessary to carefully study and consider the weathering life, beauty and cost of the product in order to make the best of its material properties. If referring to the original BASF model and industry experience, the recommended addition amount is usually between 1% and 3%. Or one to three parts by mass of the substrate, according to the type of material, the use environment, light intensity and the desired durability.
If used in plastic products, usually one to two percent to cover to prevent the polymer from fading and aging in sunlight. In case of high outdoor exposure, or the material has its own light resistance, it can be adjusted to about 300% as appropriate. If it is used for coatings, paints, etc., it can also work within 200%. However, it should be used in combination with antioxidants and other light stabilizers to combine the formula. In addition, Melagard MC has good dispersibility and is easy to mix evenly. However, it should be prepared to prevent agglomeration and ensure uniform distribution in the microstructure of the substrate to show its protective effect.
However, excessive addition is not easy to cause damage, not only increasing costs, but also causing changes in the viscosity and mechanical properties of the formulation system, and even affecting the transparency and color of the product. It should not be ignored. And when used in combination with other auxiliaries, it is especially recommended to refer to the comprehensive formula to avoid antagonism or poor compatibility. For the best effect, first conduct a small-scale test, from low to high, and gradually consider the obtained weather resistance and aesthetic performance, and gradually obtain the appropriate "gold" content.
Therefore, Melagard MC is recommended to add one to three mass percent in conventional polymer materials. However, the final dosage should be weighed and adjusted according to the product type, application environment, formulation system and desired performance, and be carefully verified. Only by carefully observing the proportion and joining the public materials can it exert its excellent effect, extend the life of the product, and demonstrate the ingenuity of the manufacturer.
