The impact of harmful substances in marine antifouling paint on the marine ecosystem is one of the main reasons for prohibiting its use. The marine ecosystem is complex and sensitive, and harmful substances in marine antifouling paint may destroy the balance of this system.

The waterproof effect of polyurethane waterproof paint is closely related to the number of layers applied. In building construction, it is usually recommended to apply 2 to 3 layers of polyurethane waterproof paint to ensure that the coating thickness is uniform and dense to achieve the best waterproof effect.

The best bottom paints for epoxy resin paint are: 1. Epoxy bottom paint 2. Polyurethane bottom paint 3. Alkyd bottom paint 4. Inorganic zinc silicate bottom paint

The answer is yes! Under the premise of meeting the appropriate construction process, material selection and function enhancement (especially anti-slip treatment), marine paint is fully capable of long-term protection of decks.

Common types of bottom paint for rusty metal are: 1. Zinc-rich bottom paint 2. Epoxy bottom paint 3. Polyurethane bottom paint 4. Acrylic bottom paint 5. Phosphate bottom paint

For some special ships, such as merchant ships or fishing boats, which have long sailing time and are usually in a harsh environment, these ships may require thicker antifouling paint coatings, and the coating thickness is generally between 250 and 300 microns.

The shelf life of the primer after opening is closely related to the storage environment, but it is usually significantly shortened, about 6 months to 1 year. If the primer is not stored properly, the shelf life may be further shortened, and it may even be unusable within a few weeks.

The drying time of polyurethane waterproof paint is divided into three parts: surface drying time (4 to 8 hours), actual drying time (24 to 48 hours), and complete curing time (7 days).

Micaceous iron oxide is a natural mineral that is processed to form a flaky iron oxide pigment. Its main component is Fe₂O₃, and its color is usually gray-black or silver-gray. The flaky structure enables it to form a fish-scale-like arrangement in the paint, enhancing the barrier properties of the paint film.

The main difference between acrylic enamel paint and alkyd enamel paint is their composition and formula. Acrylic enamel paint uses acrylic resin, while alkyd enamel paint is based on alkyd resin, which is obtained by esterification of fatty acids and diols.
