Water-washable glass protective ink (also known as hot water peelable temporary glass protective ink) is a temporary protective ink specially designed for glass processing. It uses water-based acrylic/polyurethane resin as the main film-forming substance, and forms a dense protective film after curing. After processing, the film can be quickly and completely removed with warm water/low concentration weak alkaline water. It does not require strong acid, strong alkali, or highly polluting solvents. It is an environmentally friendly protective consumable that replaces traditional solvent-based peelable inks and strong alkali release inks.
This water-soluble glass protective ink is specially formulated to achieve superior printing results when used with our advanced screen printing machines and high-quality screen printing equipment. Our low-temperature water-soluble glass protective ink is designed for ease of use, featuring self-drying or quick-drying properties to ensure fast and efficient production. Unlike traditional inks, our low-temperature water-soluble glass protective ink is water-soluble. This property makes it easy to clean and significantly reduces the need for harsh chemicals. Simply rinse your printing equipment and screen with water to start the next project. This not only saves you time and effort but is also an environmentally friendly option.
Water-based glass protective inks have special requirements for the ink's properties. This ink is smooth and has excellent screen removal properties! This product is a green and environmentally friendly product! The water-based formula has a lower odor and is more environmentally friendly! Our products have obtained international air and sea freight certifications! Shipping is more convenient and faster! Commonly used colors are black and blue. Primarily used for protecting easily scratched products such as glass and metal sheets! This coating can be removed with 5% alkaline water (acid and alkali resistant).
