Adhesion of polyurethane paint
Polyurethane paint adhesion refers to whether the paint Coating can firmly adhere to the surface of the substrate after coating. Good bonding performance can ensure that the Coating is not easy to peeling or disbonding.

Difference Between Adhesion and Bond Strength
Adhesion and bond strength are two important indicators for evaluating the bonding performance of materials. Adhesion mainly tests the adhesion of thin coatings to hard substrates, focusing on the failure mode; while bond strength focuses on the tensile strength of thicker coatings or building materials, focusing on the final tensile value. The two are applicable to different fields and test methods.

How to Improve the Adhesion of Polyurethane Furniture Topcoat?
How to improve the Adhesion of polyurethane furniture topcoat? In the painting practice of polyurethane paint, it is found that when water-based putty or colloidal putty is used as a base and then closed with shellac paint, the Adhesion of polyurethane film is not satisfactory, peeling, blister phenomenon is serious, and heat resistance is poor. The thicker the nymph glue primer, the worse the Adhesion of the polyurethane cool Varnish film.
- What is the chalking of the paint film and how is it determined?

Why can't polyurethane paint be diluted with ordinary diluting agent?
Why can't ordinary diluting agents be used to dilute polyurethane paint? One of the components of polyurethane paint is a compound containing isocyanate groups, which chemically reacts to form a polymer when it encounters a compound containing a group.

Why is shellac not declared a primer for polyoxygenated paint finishes?
Why is shellac not declared as a primer for polyoxy paint finish? Because shellac primer has a good sealing effect, people have been accustomed to using shellac paint as a base to make woodware for a long time, but it has been proved by practice that shellac paint is used as a primer for polyurethane paint finish. Adhesion difference between the base and the topcoat often occurs, and even a large area of peeling occurs. What is the reason?
Selection
Polyurethane paint adhesion refers to the adhesion ability between the paint film and the substrate, that is, the degree of adhesion between the paint film and the bottom layer. The detection can use the shear disbonding test, which applies a certain shear force between the paint film and the substrate, and then measures the adhesion strength of the paint film. Better adhesion means that the paint film can firmly adhere to the substrate and is not easy to disbond.
