1. Introduction

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 properties such as rapid drying, good adhesion, weather resistance, etc. As a multifunctional additive, DMAEE (dimethylaminoethoxy) plays an important role in environmentally friendly coatings. This article will discuss in detail the rapid drying and excellent adhesion of DMAEE in environmentally friendly coatings, and provide relevant product parameters and practical application cases.

2. Basic characteristics of DMAEE dimethylaminoethoxy

DMAEE (dimethylaminoethoxy) is a colorless to light yellow liquid with the following basic characteristics:

Chemical formula: C6H15NO2
Molecular Weight: 133.19 g/mol
Boiling point: about 200°C
Density: 0.95 g/cm³
Solubilization: Easy to soluble in water and most organic solvents
pH value: alkaline

DMAEE has excellent wetting, dispersing and stability, so that it can effectively improve the performance of the coating in the coating.

3. Application background of DMAEE in environmentally friendly coatings

The development trend of environmentally friendly coatings is to reduce VOC emissions and improve the environmentally friendly performance of the coatings. As a low VOC additive, DMAEE can significantly reduce the VOC content of the paint without affecting the performance of the paint. In addition, DMAEE also has excellentDrying properties and adhesion make it an important ingredient in environmentally friendly coatings.

4. Rapid drying effect of DMAEE in coatings

4.1 Drying mechanism

DMAEE can react with the resin and curing agent in the coating through the amino and hydroxyl groups in its molecular structure, accelerate the cross-linking reaction of the coating, thereby shortening the drying time of the coating. The specific mechanism is as follows:

Amino reaction: The amino group in DMAEE reacts with the carboxyl or epoxy group in the resin to form stable chemical bonds and accelerate the curing of the coating.
Hydroxy reaction: The hydroxyl group in DMAEE reacts with the isocyanate group in the curing agent to form a carbamate bond, further accelerating the drying of the coating.

4.2 Comparison of drying time

The following table shows the effects of different DMAEE addition amounts on the paint drying time:

DMAEE addition amount (%)	Table drying time (minutes)	Practical work time (hours)
0	30	6
1	20	4
2	15	3
3	10	2

It can be seen from the table that with the increase in the amount of DMAEE, the drying time of the paint is significantly shortened.

5. Excellent adhesion of DMAEE in coatings

5.1 Adhesion mechanism

DMAEE can form hydrogen bonds and chemical bonds with the surface of the substrate through the amino and hydroxyl groups in its molecular structure, thereby improving the adhesion of the coating. The specific mechanism is as follows:

Hydrogen bonding: The hydroxyl group in DMAEE forms hydrogen bonds with the hydroxyl group on the surface of the substrate, enhancing the adhesion of the coating.
Chemical bonding action: The amino group in DMAEE reacts with the active groups (such as carboxyl groups and epoxy groups) on the surface of the substrate to form stable chemical bonds and further improve adhesion.

5.2 Adhesion test

The following table shows the different DEffect of MAEE addition amount on coating adhesion:

DMAEE addition amount (%)	Adhesion (level)
0	2
1	1
2	0
3	0

It can be seen from the table that with the increase in the amount of DMAEE, the adhesion of the coating is significantly improved.

6. Synergistic effects of DMAEE and other additives

DMAEE not only plays a role alone in the coating, but also produces synergistic effects with other additives, further improving the performance of the coating. Here are the synergies of DMAEE and several common additives:

6.1 Synergistic effect with leveling agent

DMAEE is used in conjunction with leveling agents to significantly improve the leveling of the coating and reduce the surface defects of the coating. The specific mechanism is as follows:

Enhanced Wetting: The wetting properties of DMAEE can help the leveling agent be better dispersed in the paint and improve the leveling effect.
Surface tension reduction: DMAEE can reduce the surface tension of the coating, making it easier for leveling agent to spread on the coating surface and reduce surface defects.

6.2 Synergistic effects with defoaming agent

DMAEE is used together with defoaming agents to effectively reduce bubbles in the coating and improve the surface quality of the coating. The specific mechanism is as follows:

Reduced bubble stability: DMAEE can reduce the stability of bubbles, making defoaming agents more likely to destroy bubbles.
Accelerating bubble discharge speed: DMAEE can accelerate the bubble discharge speed and reduce bubble residues in the coating.

6.3 Synergistic effects with thickener

DMAEE is used in conjunction with thickeners, which can significantly improve the viscosity of the coating and improve the construction performance of the coating. The specific mechanism is as follows:

Intermolecular force enhancement: DMAEE can enhance the force between thickeners and increase the viscosity of the coating.
Rheological performance improvement: DMAEE can improve the rheological performance of the coating and make the coating easier to control during construction.
