60/40 Polyester Epoxy Resin for Fast Curing Hybrid Powder Coatings

 

 

◇ Introduction:

 

HH2686 is a carboxyl polyester resin designed for 60/40 hybrid powder coatings.

The so-called leveling property of the coating refers to the smooth and smooth state of the coating film after the coating is applied. The surface with good leveling property should have no irregularities such as orange peel, brush marks, ripples, and shrinkage holes.

The factors affecting the leveling of powder coatings mainly include three aspects:

1. Leveling additives: Add appropriate leveling additives to the formula of powder coatings. When the powder coating is melted, these additives can quickly reduce the surface tension of the coating, promote the rapid flow of the coating before curing and film formation, eliminate or reduce orange Surface defects such as skin, brush marks, ripples, shrinkage holes, etc.

2. The melt viscosity of powder coatings: For thermosetting powder coatings, in the process of melt flow, along with the cross-linking curing reaction, the higher the temperature, the faster the curing reaction, the faster the viscosity of the system rises, the shorter the flow time, the faster the leveling Sex is restricted. Therefore, the melt viscosity of powder coatings cannot accurately reflect the final leveling property of the coating film, and the effects of baking process, heating rate, cross-linking curing temperature, etc. on the leveling property of the coating film must be considered at the same time.

3. Baking process: There is a heating process during baking after powder coating is applied, and the heating rate has a considerable impact on the leveling of the coating; under different heating rates, the dynamic viscosity changes with temperature. The trend is basically the same, that is, the beginning The viscosity decreases with the increase of temperature and reaches a minimum value, and then the viscosity increases with the increase of temperature, which is caused by the cross-linking reaction. More importantly, the faster the heating rate, the smaller the minimum value of the viscosity, and the higher the corresponding temperature, the better the curing of the coating film and the better the leveling of the coating film.
