UV three-proof paint is beneficial to improve the production efficiency of automated production lines and effectively improve product yield.  As Multi-layer PCB knows that, in actual use, according to process requirements and characteristics, you can choose machine spraying, manual gluing, etc., partial or entire board glue coating, and then curing by UVLED curing equipment to achieve the three-proof effect. The main advantages are as follows:

1. Environmental protection and safety

1.1. UV glue does not contain VOC volatiles and does not pollute the ambient air;

1.2. There are relatively few restrictions or prohibitions on UV glue components in environmental protection laws and regulations;

1.3. No solvent, low flammability.

2. Economical and cost-saving

2.1. UV glue has a fast curing speed, which is conducive to automated production lines and improves labor productivity;

2.2. Testing and handling can be carried out after curing, saving space;

2.3. UVLED curing equipment is a cold light source, often (low) temperature curing, saving energy. For example, the energy required to produce 1g of light-curing pressure-sensitive adhesive only needs 1% of the corresponding water-based adhesive and 4% of the solvent-based adhesive. It can be used for materials that are not suitable for high temperature curing. Compared with thermosetting resin, the energy consumed by UV curing can save energy consumption by 90%;

2.4. Small size, less area, saving space;

2.5. UV glue coating only needs a very thin layer, which saves the amount and reduces the cost;

2.6. One-component system, no need to mix, easy to use.

3. Compatibility

3.1. Materials that are sensitive to temperature, solvents and moisture can be used;

3.2. The curing time, curing degree, etc. are adjustable, making the operation more intelligent and convenient;

3.3. It can be applied repeatedly and cured for many times;

3.4. UVLED curing equipment can be easily installed on the existing production line without major changes;

3.5. UV three-proof glue, for the shadow area that cannot be irradiated by UV light, it can be cured by secondary moisture.
