What are the characteristics of aging of epoxy floor paint film?
The deterioration of floor paint is a common issue that affects both aesthetics and functionality. One of the earliest signs of aging is the loss of shine, which occurs due to prolonged exposure to ultraviolet (UV) rays. These rays trigger photochemical reactions that break down the epoxy resin components in the paint, leading to a gradual loss of luster. For decorative floor paints, gloss is a critical metric, as a matte finish diminishes the visual appeal entirely. Proper topcoating with suitable architectural finishes can enhance radiance, plumpness, and vividness. This not only depends on the correct choice of paint but also reflects the skill level of the application process.
Discoloration is another prominent sign of aging, where the paint shifts from its original hues, turning darker, lighter, or even developing milky tones. This phenomenon results from UV-induced photochemical changes, with the nature of the pigment playing a crucial role. Different pigments possess varying degrees of lightfastness, affecting how well they retain their color over time.
Peeling and flaking represent advanced stages of paint degradation. These issues stem from the breakdown of the epoxy resin’s molecular bonds under UV radiation and oxygen exposure, causing separation between the resin and pigment particles. Additionally, the crystalline structure of the pigments contributes significantly to this process. Flaking usually occurs when the coating has already suffered severe damage or complete loss, indicating compromised protective qualities and diminished aesthetic integrity.
Poor-quality epoxy resin paints often lead to issues like peeling, cracking, and overall unsatisfactory performance. When renovating such surfaces, conflicts arise between new materials and existing pavements, necessitating careful planning. Removing old coatings typically involves mechanical methods like polishing or high-pressure spraying, with mechanical polishing being the most popular due to its efficiency compared to manual techniques or pressure washing.
