Today
when the technical workers of FLDC coating factory talk about this topic, we need to understand the differences between the two paints.
There are many types of paints and coatings. Many coatings have similar performances and names that are difficult to distinguish. Among them,
acrylic polyurethane topcoat and acrylic paint are commonly used industrial anti-corrosion coatings. There are many differences in performance between the two.
Let’s take a closer look.
First
let’s take a look at the commonalities between acrylic polyurethane topcoat and acrylic paint, that is, the similarities:
1. Excellent weather resistance: Excellent outdoor weather resistance and UV resistance, and the paint film will not powder after long-term use.
2. Full gloss: The paint film has good gloss, beautiful paint film, and high brightness.
3. Similar construction process: Both can be sprayed and brushed.
4. Good decorative effect: The paint film has various colors, and all colors can be modulated, including plain colors, colors and silver.

The differences are mainly reflected in the components, curing agents, diluents, construction processes, components, drying methods, supporting systems and application areas.
| Differences | Acrylic polyurethane topcoat. | Acrylic topcoat |
| Components | Two-component coatings. | Single-component paint |
| Curing agent | A special curing agent is required. | No curing agent required |
| Diluent | Matching acrylic polyurethane curing agent. | Matched with acrylic curing agent |
| Applicable period | The mixed paint must be used up within 6 hours. | Unlimited use time |
| Composition | Component one is hydroxyl acrylic resin, additives, solvents, and component two is polyurethane resin. | Methacrylate, additives, pigments and fillers |
| Drying method | The main paint and curing agent undergo cross-linking and curing reaction. |
Physically dry |
| Supporting system | And two-component epoxy primers, zinc-rich primers, polyurethane primers, epoxy micaceous iron intermediate paints and other matching coatings. |
Coated with acrylic primer |
| Application areas | Large steel structures, building exterior walls, mechanical equipment, bridge structures, tank anti-corrosion and other fields. |
Used for construction machinery, equipment and machinery coating |
Acrylic polyurethane topcoat and acrylic paint have their own characteristics, and users can choose according to their needs.
Many countries require the use of bridges, steel structure projects, etc. It has a good anti-corrosion effect. The anti-corrosion coatings, steel structure anti-corrosion paints, and engineering anti-corrosion coatings produced by Fulaid have good stability and strong resistance to ultraviolet rays. Outdoor coatings can be protected for more than 20 years
