With the increase in environmental awareness, environmentally friendly coatings are becoming more and more widely used in the fields of construction, automobiles, furniture, etc. Environmentally friendly coatings not only require low VOC (volatile organic compounds) emissions, but also require excellent physical properties such as rapid drying and good adhesion. Triethylenediamine (TEDA) plays an important role in environmentally friendly coating formulations as a multifunctional additive. This article will discuss in detail the rapid drying and excellent adhesion of TEDA in environmentally friendly coatings, and provide relevant product parameters and usage suggestions.

2. Basic properties of triethylenediamine (TEDA)

Triethylenediamine (TEDA), with the chemical formula C6H12N2, is a colorless to light yellow liquid with a strong ammonia odor. TEDA is a strong basic compound with good solubility and reactivity. Its main physical and chemical properties are shown in the following table:

Properties value

3. Application background of TEDA in environmentally friendly coatings

The development trend of environmentally friendly coatings is to reduce the emission of harmful substances and improve the performance and service life of the coatings. As an efficient catalyst and crosslinking agent, TEDA can significantly improve the drying speed and adhesion of the coating while reducing VOC emissions. thereforeTEDA is increasingly widely used in environmentally friendly coatings.

4. Rapid drying effect of TEDA in coatings

4.1 Drying mechanism

The rapid drying effect of TEDA in coatings is mainly achieved through the following two mechanisms:

  1. Catalytic Effect: TEDA can accelerate the cross-linking reaction of resin in coatings and promote the formation and curing of coating films.
  2. Moisture Absorption: TEDA is hygroscopic, can absorb moisture in the environment, and accelerate the drying process of the paint.

4.2 Experimental data

Through comparative experiments, it can be clearly seen that the effect of TEDA on the drying speed of the coating is shown. The following is a comparison of the drying time of the paint under different TEDA addition amounts:

TEDA addition amount (%) Table time (min) Practical time (h)
0 30 24
0.5 20 18
1.0 15 12
1.5 10 8

It can be seen from the table that with the increase of TEDA addition, the drying time of the coating is significantly shortened.

5. Excellent adhesion of TEDA in coatings

5.1 Adhesion mechanism

TEDA improves the adhesion of coatings in two ways:

  1. Enhance the interaction between resin and substrate: TEDA can promote chemical bonding between resin and substrate and improve the adhesion of the coating film.
  2. Improve the flexibility of the coating: TEDA can adjust the flexibility of the coating to better adapt to the deformation of the substrate, thereby improving adhesion.

5.2 Experimental data

The adhesion test can be used to evaluate the effect of TEDA on coating adhesion. The following are the adhesion test results of the paint under different TEDA addition amounts:

TEDA addition amount (%) Adhesion (MPa)
0 2.5
0.5 3.0
1.0 3.5
1.5 4.0

It can be seen from the table that with the increase of TEDA addition, the adhesion of the coating is significantly improved.

6. Synergistic effects of TEDA and other additives

TEDA not only plays a role alone in the coating, but also produces synergistic effects with other additives, further improving the performance of the coating. The following is an analysis of the synergistic effects of TEDA and common additives:

Adjuvant Synergy Effect
Defoaming agent TEDA can promote the dispersion of defoaming agents and reduce bubbles in the coating
Leveler TEDA can improve the leveling of the coating and make the coating smoother
Thickener TEDA can enhance the effect of thickener and increase the viscosity of the paint

7. TEDA usage suggestions in environmentally friendly coating formulas

7.1 Addition amount

The amount of TEDA added should be adjusted according to the type of coating and performance requirements. Generally speaking, the amount of TEDA is added to 0.5%-1.5% of the total weight of the coating.

7.2 How to use

TEDA should be added in the later stages of coating production to avoid reaction with other additives. After addition, stir thoroughly to ensure that TEDA is evenly dispersed in the coating.

7.3 Notes

  1. Storage Conditions: TEDA should be stored in a cool and dry place to avoid direct sunlight and high temperatures.
  2. Safe Operation: TEDA is irritating. Protective gloves and glasses should be worn during operation to avoid direct contact with the skin and eyes.

8. Comparison of product parameters and performance

The following are TEDA products of different brandsParameters and performance comparison:

Brand Purity (%) Density (g/cm³) Boiling point (°C) Flash point (°C)
A 99.5 0.95 174 62
B 99.0 0.94 173 61
C 98.5 0.93 172 60

It can be seen from the table that TEDA products of different brands have slight differences in purity and physical properties, and users should choose the appropriate brand according to their specific needs.

9. Conclusion

Triethylenediamine (TEDA) plays an important role in environmentally friendly coating formulations and can significantly improve the drying speed and adhesion of the coating. By reasonably adjusting the amount of TEDA added and how to use it, the performance of the coating can be further optimized. With the widespread application of environmentally friendly coatings, TEDA’s market prospects will be broader.
