The importance of anti-yellowing agents
Extend service life
The presence of anti-yellowing agent allows the epoxy resin coating to resist time erosion and significantly extend its service life. For flooring, this means that even after years of use, the initial shine and color can still be maintained without frequent refurbishment or replacement.
Enhance aesthetics
As one of the core elements of interior decoration, the flooring directly affects the living experience. The anti-yellowing agent ensures that the floor always presents a fresh and bright effect by preventing the coating from discoloring, adding more vitality and warmth to the home.

Reduce maintenance costs
Once the floor coating without anti-yellowing agent turns yellow, it often requires re-sanding, painting or even replacing the entire floor, which undoubtedly adds an additional financial burden. Products that use anti-yellowing agents can maintain good condition through simple cleaning and maintenance, greatly reducing the cost of later maintenance.
Environmentally friendly
Some high-quality anti-yellowing agents are made of renewable resources and have low emissions of volatile organic compounds (VOCs), which meets the requirements of modern society for green and environmental protection. In addition, the reduction of the need for waste disposal caused by yellowing also indirectly promotes the development of a resource-saving society.

Correct usage method
Stir well
Always stir thoroughly the mixture of anti-yellowing agent and epoxy resin before use to ensure that all ingredients are evenly distributed. Failure to do so may result in insufficient local protection or uneven coating.
Control dosage
Too much or too little anti-yellowing agents will affect the final effect. It is generally recommended to add it according to the manufacturer’s instructions, and if necessary, you can determine the best ratio through experiments.
Construction Environment
Environmental conditions such as temperature and humidity are crucial to the performance of anti-yellowing agents. Ideally, construction should be carried out in an environment with a temperature of 15-30°C and a relative humidity below 75% to ensure the smooth progress of the coating curing process.
Super maintenance
The newly laid floor coating takes some time to fully cure. During this period, heavy objects or chemical contact should be avoided to prevent damage to the protective layer formed by the anti-yellowing agent.
Mechanism of action of anti-yellowing agent
Absorb UV rays
Ultraviolet rays are one of the important factors that cause epoxy resin to turn yellow. Anti-yellowing agents usually contain ultraviolet absorbers (UVAs), these substancesMass can selectively absorb ultraviolet rays and convert them into thermal energy to release them, thereby avoiding the direct effect of ultraviolet rays on the epoxy resin molecular chains, causing molecular bond breakage and free radical formation.
Capture free radicals
Under light or heating conditions, free radicals may be generated inside the epoxy resin, and these unstable chemically active species will further induce chain reactions, resulting in changes in molecular structure and discoloration. Antioxidant components in anti-yellowing agents (such as hindered amine compounds) can quickly bind to free radicals to terminate their chain reactions, thereby protecting the resin from damage.
Prevent oxidation reactions
The presence of oxygen will also accelerate the aging process of epoxy resin. Certain anti-yellowing agents delay the occurrence of oxidation reactions by forming a protective film or isolating oxygen from the outside, preventing it from contacting with the resin.
Stable molecular structure
Some high-performance anti-yellowing agents can also enhance the stability of the molecular chain of epoxy resin, making them more resistant to external environmental changes. For example, by adjusting the crosslink density or optimizing the molecular arrangement, the resin is less susceptible to external stimulation and deterioration.
