Anonymous users2024-01-24PU paint is actually the English abbreviation of two-component polyurethane paint. The ratio varies from factory to factory, generally from 3:1 to 5:
1, which refers to the ratio between the paint paste (colored) component and the hardener (generally colorless and transparent). The amount of thinner should be determined according to the initial viscosity of the paint, the ambient temperature when spraying, the painting method and the thickness and appearance requirements of the film. It is recommended that you find someone who can spray paint for advice.

Anonymous users2024-01-23You see whether it is water-based paint or oil-based, water-based paint is environmentally friendly and non-toxic, and oily paint is generally an organic solvent and is toxic. After the oily multi-ventilation is dried, the organic solvent will become moldy and will be no longer toxic.
The solid content of the varnish produced by each manufacturer is different, and the amount of curing agent and diluent added is also different. >>>More
The curing agent is generally general, but there are good and bad, it depends on the solid content of the curing agent, if the solid content is low, then the paint film is not easy to dry and the paint film hardness is not enough.
It is written on the packaging of the paint!
Generally, the ratio of paint to solid and dilute is: 1 or. >>>More
At present, the domestic true yellow-resistant curing agent is mostly mixed with 75% solid yellow-resistant solidifier, trimer curing agent and TDI curing agent contained in Mitsui from Germany and Japan. The proportion is inconvenient to disclose, forgive me.
p-hydroxybenzene sulfonic acid, also known as phenol sulfonic acid, has a molecular formula of C12H10N2O4S and a molecular weight, which is mainly used for resin curing, the most important additive in the acid tin plating process, and also has the effect of acid resin foaming for organic intermediates. >>>More
