How to make the coating of the scratch card?
The coating of the scraping card is usually made of a special material covering it. Here is a common production method:
Preparation of substrate: Firstly, choose a suitable substrate, usually using paper, plastic, or other thin and sturdy materials.
Make coating mixture: Make coating mixture as needed. This typically includes coatings or inks as well as additives such as pigments, pigment solvents, polymers, and adhesives.
Coating: Apply the mixture evenly onto the substrate, which can be applied using methods such as scraping, spraying, or printing.
Drying and curing: After the coating is evenly applied, place it in an appropriate environment for drying and curing. This can be achieved through natural air drying or accelerated drying using heating equipment.
Add scraping layer: After the coating is completely dry and cured, add a layer of scrapeable metal foil or coating, usually silver gray.
Making patterns: Design and print the required patterns on the scratch layer, such as numbers, text, or images.
The above is a general method for making scratch card coatings. The actual production process may vary depending on the material and manufacturer.
