Overview:
S-531 is a water-soluble special polyester resin containing hydroxyl groups. It has excellent adhesion to substrates such as PET and glass, and can be used as a temporary protective coating for glass, metal, and plastic. The coating becomes colorless and transparent after curing. It is easy to use and can be cured by self-drying or low-temperature baking. If it needs to be removed after curing, it can be done using room temperature water or by using ultrasonic water.
Characteristics:
* No VOC (Volatile Organic Compounds), with excellent environmental friendliness
* Strong adhesion, suitable for various substrates
* Easy to remove after coating, can be removed by ultrasonic water or normal temperature water
