Permanent industrial paint markers create markings on various surfaces, allowing users to classify, label, and identify items. These markings are durable and resist fading, making them ideal for production or other environments where long-term identification and classification are crucial. They are made with many different formulations that provide unique benefits, such as temperature resistance or the ability to glow under ultraviolet light. Some formulations are tightly controlled to comply with industry-specific restrictions such as in aerospace or scientific applications.
