Wrinkle paint is a special paint that can form an irregular wrinkle-like surface after painting, which has unique beauty and decorative properties. Wrinkle paint is widely used in furniture, electrical appliances, industrial equipment, auto parts and other fields, bringing people an unusual visual enjoyment.
The principle of wrinkle paint is to use the different shrinkage coefficients of different components in the paint, which causes uneven stress in the coating during the curing process, thus forming wrinkles. Therefore, the formula design and coating process of wrinkle paint are very important, and multiple factors such as the solid content, viscosity, leveling, drying time, curing temperature, and coating thickness of the paint need to be considered.
In the formula of wrinkle paint, the main resin is the key component that affects the wrinkle effect. It determines the flexibility, adhesion, weather resistance and other properties of the coating. Generally speaking, the narrower the molecular weight distribution of the main resin, the more uniform the wrinkle effect and the higher the quality of the wrinkle paint.
Evonik's polyester resin DYNAPOL LH831-24N is a main resin designed for wrinkle paint formulations. It has the following performance advantages:
- The molecular weight distribution is relatively narrow, which can produce a uniform wrinkle effect and improve the aesthetics and decorativeness of the wrinkle paint;
- High solid and low viscosity, with a solid content of 70%, which can reduce the amount and cost of coatings, while improving the leveling and drying speed of the coatings;
- It has excellent adhesion and flexibility to metals and can be applied to substrates of different shapes and materials to ensure the integrity and durability of the coating;
- Good weather resistance, can meet the needs of indoor or outdoor building materials coatings, home appliance panel coatings and other fields, and ensure the color and gloss of the coating film.
Evonik polyester resin DYNAPOL LH831-24N is a very cost-effective polyester resin that can help you create high-quality wrinkle paint effects and make your products more outstanding.
Notes on recipe adjustment
When using Evonik polyester resin DYNAPOL LH831-24N as the main resin in wrinkle paint formulations, there are some precautions to be aware of. Here are some common questions and answers:
①Q: Can leveling agent be added to the formula?
A: It is not recommended to add leveling agent, because too high leveling will reduce the effect of wrinkles, resulting in less obvious or uneven wrinkles. If the leveling of the coating is not good, the viscosity or curing temperature can be adjusted appropriately.
②Q: Can matting powder be added to the formula?
A: You can add a small amount of matting powder to the formula to control the stability of the wrinkle paint and prevent the wrinkle paint from changing during storage or transportation. However, the amount of matting powder should not be too much, otherwise it will affect the glossiness and decorativeness of the wrinkle paint.
