Sustainable coatings are environmentally friendly finishes used on various surfaces, such as wood, metal, and plastic. These coatings are designed to minimize harmful impacts on the environment by using natural or recycled materials, reducing volatile organic compounds (VOCs), and promoting energy efficiency during production and application. These coatings often include bio-based ingredients, which are derived from renewable resources like plants. By choosing sustainable coatings, consumers can help reduce pollution, conserve resources, and support a healthier ecosystem while still achieving durable and attractive finishes for their projects.
