The gloss of bis-(2-dimethylaminoethyl) ether in high-end furniture painted surfaces
Introduction
In modern home decoration, the gloss of paint on high-end furniture is one of the important indicators to measure its quality. Gloss not only affects the beauty of the furniture, but also directly affects its durability and difficulty in maintaining. In order to improve the gloss of furniture paint surfaces, many chemical additives have been introduced into coating formulations, among which bis-(2-dimethylaminoethyl)ether (DMAEE for short) has become one of the key components to enhance gloss due to its unique chemical properties. This article will discuss in detail the application of DMAEE in high-end furniture paint surfaces, including its chemical characteristics, mechanism of action, product parameters and practical application effects.
1. Chemical characteristics of bis-(2-dimethylaminoethyl) ether
1.1 Chemical structure
The chemical formula of bis-(2-dimethylaminoethyl)ether is C8H18N2O, and its structure contains two dimethylaminoethyl groups, connected by an oxygen atom. This structure imparts DMAEE’s unique chemical properties, allowing it to exhibit excellent dispersion and stability in the coatings.
1.2 Physical Properties
| parameters | value |
|---|---|
| Molecular Weight | 158.24 g/mol |
| Boiling point | 210-215°C |
| Density | 0.92 g/cm³ |
| Flashpoint | 93°C |

1.3 Chemical Properties
DMAEE has the following chemical properties:
- Abstract: The amino group in the DMAEE molecule makes it alkaline, can react with acidic substances, and adjust the pH value of the coating.
- Disperity: DMAEE can effectively disperse pigments and fillers, improving the uniformity and gloss of the paint.
- Stability: DMAEE exhibits good stability under high temperature and light conditions and is not easy to decompose.
2. The mechanism of action of DMAEE in coatings
2.1Dispersive effect
DMAEE adopts adsorption of amino groups in its molecules with pigments and fillers surfaces to form a stable dispersion system. This dispersion can effectively prevent the agglomeration of pigments and fillers, and improve the uniformity and gloss of the coating.
2.2 Leveling
DMAEE can reduce the surface tension of the paint and improve the leveling of the paint. Increased leveling helps the coating to form a smooth surface during curing, thereby enhancing gloss.
2.3 Curing promotion effect
The amino group in DMAEE can react with the curing agent in the coating, accelerating the curing process of the coating. Rapid curing helps reduce defects on the paint surface and improves gloss.
3. Application of DMAEE in high-end furniture painted surfaces
3.1 Coating formula
In high-end furniture paint finishes, DMAEE is usually added to the coating formulation as an additive. Here is a typical example of a paint formula:
| Ingredients | Proportion (%) |
|---|---|
| Resin | 60 |
| Pigments | 20 |
| Filling | 10 |
| DMAEE | 2 |
| Solvent | 8 |
3.2 Application process
DMAEE’s application process in high-end furniture paint includes the following steps:
- Ingredients: Mix each component evenly according to the formula ratio.
- Dispersion: Use a high-speed disperser to disperse pigments and fillers in the resin, and add DMAEE to improve the dispersion effect.
- Leveling: Apply the paint to the surface of the furniture and use the leveling action of DMAEE to form a smooth coating.
- Currect: Curing the coating under appropriate temperature and humidity conditions, DMAEE accelerates the curing process and improves gloss.
