Advantages of Polyester Resins for TGIC Based Formulations in Outdoor Applications
1. Excellent Weather Resistance
Polyester Resins For TGIC Based Formulations show excellent weather resistance in outdoor environments. Its cured product has high hardness and good wear resistance, which can effectively resist the erosion of natural factors such as ultraviolet rays, wind and sand, and rain, and maintain long-term stability and aesthetics. The resin has strong chemical corrosion resistance and can resist the erosion of various chemicals, ensuring the durability and reliability of the coating.
2. Fast Curing Characteristics
Polyester resins for TGIC based formulations have the characteristics of fast curing and can achieve efficient curing at lower temperatures. Compared with traditional coatings, this resin shortens the curing time and improves production efficiency. For example, Y29803, Y29803A, Y29810 and other types of resins can be cured in just 12 minutes at 200°C, which improves the overall production cycle of the production line and meets the high requirements of the modern coatings industry for production efficiency.
3. Environmentally friendly and harmless characteristics
TGIC based polyester resin uses TGIC as a curing agent, and no harmful substances are released during the curing process, which meets environmental protection requirements. The cured product of this resin has good adhesion and wear resistance, which can reduce rework and scrap rates caused by coating defects and improve production efficiency. Its environmental protection characteristics also make this resin more popular in outdoor applications, which meets the needs of modern society for environmentally friendly coatings.
How to choose the right TGIC based polyester resin
1. Select the resin type according to the application scenario
Selecting the right Polyester Resins For TGIC Based Formulations requires selecting the right resin type according to the specific application scenario. For example, Y29803 is suitable for general industry, Y29803A is suitable for high gloss, anti-bending, fast curing, and baking resistance, and Y29810 is suitable for building materials grade and good weather resistance. When choosing, the application scenario and product type should be considered to ensure that the performance of the resin matches the demand, thereby improving the quality and reliability of the coating.
2. Consider the curing speed and curing temperature
The polyester resin for TGIC based formulation has the characteristics of fast curing and can achieve efficient curing at a lower temperature. When choosing, the appropriate curing speed and curing temperature should be selected according to the actual situation of the production line and the production efficiency requirements. For example, resins such as Y29803, Y29803A, and Y29810 can be cured in just 12 minutes at 200°C. The appropriate curing speed and curing temperature can improve production efficiency and meet the high requirements of production efficiency in the modern coatings industry.
3. Consider viscosity and acid value
The viscosity range of polyester resin for TGIC based formulation is usually 3.0-8.0 Pa·s (200°C), and the acid value range is usually between 28-58 mgKOH/g. When selecting, the appropriate viscosity and acid value should be selected according to the coating process and coating quality requirements to ensure the uniformity and adhesion of the coating. Appropriate viscosity and acid value can improve the quality of the coating, reduce coating defects, and improve production efficiency.
4. Consider the characteristics of the resin
Polyester resin for TGIC based formulation has the characteristics of high gloss, bending resistance, fast curing, good weather resistance, boiling water resistance, and salt spray resistance. When selecting, the resin with corresponding characteristics should be selected according to the specific application requirements to ensure the performance and reliability of the coating. For example, Y29803A is suitable for high gloss, bending resistance, fast curing, and baking resistance, and Y29810 is suitable for building material grade and good weather resistance. Appropriate resin characteristics can improve the quality and reliability of the coating and meet the needs of different application scenarios.
