Dilution ratio and usage guide for silk screen glue
Screen printing adhesive is a widely used adhesive in the screen printing industry, used to fix and protect printed patterns on the screen. The dilution ratio and usage guidelines of glue are crucial for achieving high-quality screen printing results. This article will introduce the dilution ratio and usage guide of silk screen glue to help readers better understand and use silk screen glue.
1、 Dilution ratio of silk screen glue
The dilution ratio of silk screen glue is usually determined according to actual usage needs. Here are some common dilution ratio references:
1. Use of original solution: Some screen printing adhesives can be used directly with the original solution without dilution. This type of glue is usually used for some finer printing patterns, requiring the glue to have a high concentration and viscosity to ensure the clarity and quality of the printing.
2. Dilution ratio of 1:1: This is a common dilution ratio, which involves mixing a portion of glue with a portion of water. This dilution ratio is suitable for some medium density printed patterns. The concentration and viscosity of the glue are moderate, which can effectively fix the printed patterns and also help reduce costs.
3. Dilution ratio of 1:2 or higher: For larger printed patterns or lower pattern densities, a higher dilution ratio can be chosen, which involves mixing a portion of the glue with two or more portions of water. This dilution ratio can reduce the concentration and viscosity of the glue, making it more fluid and helping to better cover the entire printing area.
It should be noted that different brands and models of silk screen glue may have different dilution requirements. Before use, refer to the product manual or consult the supplier to ensure the appropriate dilution ratio is selected.
2、 Guidelines for using silk screen glue
In addition to dilution ratio, the correct use of silk screen glue is also the key to obtaining high-quality silk screen effect. Here are some usage guidelines:
1. Clean the screen: Before using screen printing glue, it is necessary to ensure that the screen is clean and dust-free. The method of cleaning the wire mesh can include rinsing with water or using specific cleaning agents. A clean screen can provide better adhesion and printing quality.
2. Uniform coating: When applying glue, it is necessary to ensure that the glue is evenly coated on the screen. You can use tools such as a scraper or scraper to gently and evenly apply the glue to the printing area. Do not use too much force to avoid affecting the clarity of the printed pattern.
3. Drying time: After printing is completed, the silk screen glue needs to be dried. The drying time usually needs to be determined according to the type and thickness of the glue, usually between 15 minutes and several hours. During the drying period, avoid touching or moving the printed material to prevent glue from flowing or forming defects.
4. Cleaning the wire mesh: After use, it is necessary to clean the wire mesh in a timely manner to prevent glue residue and blockage of the wire mesh holes. You can use cleaning agents or warm water to clean the wire mesh, ensuring thorough removal of glue and dirt. After cleaning, the wire mesh should be air dried or blown dry with a hair dryer to prevent further contamination and damage to the wire mesh.
The above is the dilution ratio and usage guide for silk screen glue. I hope the introduction in this article can help readers better understand and use silk screen glue to achieve high-quality silk screen effects.
