What Is The Difference Between Water-based Varnish And General Varnish
Nov 11, 2023
The main differences between water-based varnishes and traditional varnishes are their composition and performance characteristics. Traditional varnishes usually use organic solvents as diluents, while water-based varnishes use water as the diluent. This difference has several consequences, which we will explore in detail below.
Environmental protection:
Water-based varnish does not contain organic solvents, so it has higher environmental protection. The use of organic solvents in traditional varnishes can produce volatile organic compounds (VOCs) that evaporate in the atmosphere and negatively impact air quality and health. In contrast, water-based varnish has lower volatility, which reduces environmental pollution and has less impact on human health.
Drying Time:
Water-based varnishes generally have faster drying times. Since water can evaporate more quickly, the painted surface will dry faster. This means that during the construction process, water-based varnish can improve production efficiency and reduce waiting time.
Taste and Odor:
Because water-based varnishes do not contain organic solvents, they emit less odor during the painting process. This helps improve the construction environment and reduce workers’ risk of exposure to harmful gases. In contrast, the organic solvents in traditional varnishes may produce a stronger chemical odor.
Drying time requirements:
Water-based varnishes generally require shorter drying times, but require waiting for complete drying to achieve best results. This means that after application, special care needs to be taken not to expose the coating to wet or humid conditions so as not to affect the final quality.
Durability: Traditional varnishes generally offer high durability and resistance to chemical attack. They provide good protection in a variety of environmental conditions and are highly resistant to chemicals. However, water-based varnishes may be slightly inferior to traditional varnishes in this regard and may require more attention and maintenance after application to ensure long-term performance.
To sum up, the differences between water-based varnish and traditional varnish involve ingredients, environmental protection, drying time, durability and odor. The choice of varnish depends on the specific application needs and factors of concern to ensure the best finish and protection.
