What is polyurethane epoxy resin yellowing resistance agent?

Polyurethane epoxy resin yellowing agent is a special additive that is widely used in coatings, plastics and composite materials to prevent or slow down the yellowing of these materials when exposed to light, heat or other environmental factors. This yellowing not only affects the appearance of the product, but may also lead to a decrease in material properties such as weakening strength and reduced toughness. Therefore, yellowing agents are particularly important in applications where materials transparency and color stability are required for a long time, such as automotive parts, optical lenses and architectural glass.

Chemical structure and function

The core of the yellowing resistance agent of polyurethane epoxy resin is its unique chemical structure, usually composed of amine compounds, hydroxy compounds and other functional additives. This type of compound has excellent antioxidant properties and ultraviolet absorption capacity, which can effectively capture free radicals and decompose peroxides, thereby preventing chain reactions from occurring. Specifically:

1. Amine compounds: As the main antioxidant component, amine compounds can bind to oxygen molecules to form relatively stable products and reduce oxidation.
2. Hydroxy compounds: These substances terminate the radical chain reaction by providing hydrogen atoms, which helps to prevent oxidation.
3. Other functional additives: including ultraviolet absorbers and light stabilizers, etc., further enhancing the overall effect of the yellowing agent.

Working Principle

When a material containing a yellowing agent is exposed to light or high temperature, the active ingredients in it respond quickly, starting a series of complex chemical reactions to protect the substrate from damage. The following are its main working mechanisms:

• Free Radical Capture: Yellowing agents can recognize and capture free radicals triggered by light, preventing them from attacking surrounding polymer chains.
• Energy Transfer: By converting the absorbed ultraviolet light into harmless heat and releasing it, the damage caused to the material by direct energy transfer is avoided.
• Decomposition of peroxides: For the peroxides that have been formed, the yellowing agent can decompose them into more stable substances to prevent them from continuing to participate in the degradation reaction.

Application Fields

Due to its outstanding performance, polyurethane epoxy resin yellowing agents are widely used in many industries, especially in products that require high transparency and long life. The following are some typical application scenarios:
