1、The Role of Formulations in the Ageing Process of Vinyl Acetate Based

Vinyl acetate (VAc)-based emulsions represent one of the main media used by modern and contemporary artists. Their long-term behaviour is still not completely understood, especially due to the scarce knowledge on the influence of other compounds in the formulation, which may impact ageing over time.

In the chemical industry, vinyl acetate is a critical organic compound with broad applications and significant economic benefits. its high-concentration use has been restricted due to environmental pollution risks during production. In recent years, with rising environmental awareness and technological advancements, the application of low-concentration vinyl acetate has gained increasing attention. This paper explores the roles and prospects of low-concentration vinyl acetate in various fields.

1. Applications in Coatings

Coatings are indispensable in modern industries for protecting metal surfaces from corrosion, enhancing aesthetics, and improving durability. Traditional coatings often contain high concentrations of vinyl acetate, resulting in high costs and harmful volatile organic compounds (VOCs) that pose environmental and health risks. In contrast, low-concentration vinyl acetate coatings have lower VOC content, making them more environmentally friendly and safer for humans and ecosystems.

Low-concentration vinyl acetate coatings are widely used in construction, automotive, and furniture industries. For example, in construction, they serve as exterior wall coatings with excellent weather resistance and decorative effects. In automotive manufacturing, these coatings reduce paint film thickness, lower production costs, and maintain gloss and color vibrancy. In furniture production, they are used as wood finishes to protect wood while enhancing aesthetic appeal.

2. Applications in Plastics

Plastics are ubiquitous in modern life, employed in packaging, construction materials, and consumer goods. Traditional plastics with high vinyl acetate content face performance limitations and environmental concerns. Developing low-concentration vinyl acetate plastics has become a key research focus.

Low-concentration vinyl acetate plastics exhibit improved mechanical and processing properties, such as higher melting points, enhanced chemical resistance, and better UV stability. These advantages expand their potential in packaging, construction, and household goods. For instance, in packaging, they can produce eco-friendly food bags and beverage bottles. In construction, they are used to manufacture doors, windows, and flooring that balance aesthetics and functionality.

3. Applications in Pharmaceuticals

In pharmaceuticals, vinyl acetate is a crucial intermediate for synthesizing drugs. Ensuring its safety and environmental friendliness is a major concern, as high-concentration formulations may harm health and ecosystems. Developing low-concentration vinyl acetate drugs is thus a priority.

Low-concentration vinyl acetate drugs have lower toxicity and irritation, making them suitable for children’s medications and oral drugs. They also reduce environmental pollution and production costs. For example, in pediatric drugs, they enhance safety and stability while minimizing adverse reactions. In oral medications, they improve bioavailability and efficacy while mitigating environmental impacts.

As an eco-friendly chemical, low-concentration vinyl acetate holds vast potential in coatings, plastics, and pharmaceuticals. With stricter environmental policies and technological progress, its applications will expand further. challenges related to cost, technology, and regulations must be addressed. In the near future, low-concentration vinyl acetate is poised to play a larger role in the chemical industry, contributing to sustainable development.
