modified polyurethane seasoning agent - Introduction
Modified polyurethane brightener is a commonly used chemical additive with the following properties:
1. bright effect: modified polyurethane brightener can give the surface of the object good gloss effect, make it look more beautiful, smooth.
2. scrub resistance: modified polyurethane brightener can increase the surface of the object scrub resistance, make it more wear-resistant, durable.
3. protection performance: modified polyurethane brightener can form a layer of protective film to prevent the surface of the object from pollution, oxidation and other violations.
The main uses of modified polyurethane brighteners are:
1. wood products: can be used for wood flooring, furniture and other wood products surface coating, increase its brightness and durability.
2. metal materials: can be used for metal surface coating, improve the brightness and oxidation resistance of metal.
3. plastic products: can be used for surface treatment of plastic products, so that it has a better gloss effect.
The preparation method of modified polyurethane brightener is mainly obtained by chemical synthesis, and the specific preparation method is different due to the structural and functional requirements of various modified polyurethanes.
in the use of modified polyurethane brightener need to pay attention to its safety information:
1. Avoid touching eyes and skin. If there is contact, rinse immediately with plenty of water.
2. avoid inhalation of its steam or dust, if there is inhalation, should be quickly away from the scene, keep the respiratory tract unobstructed.
3. in the use of the process should pay attention to a well-ventilated place, avoid operating in a confined space.
4. If accidentally swallowed, seek medical attention immediately.
When storing the modified polyurethane brightener, it should be kept in a dry, cool, dark place to avoid contact with fire or oxidant.
