SPA solvent type screen printing ink characteristics

SPA screen printing inks are made of a combination of special PVC polymers and high-grade organic pigments and special solvents. They have good adhesion to PVC products, excellent physical, chemical, heat resistance, and cold resistance. Special high-frequency welding, has a unique effect.
[ Product Features]
1. Printability, good flatness.
2. With high gloss, resistant to toluene.
3. Adhesion, anti-adhesion, heat resistance, good cold resistance.
4. Good tortuosity, excellent high frequency bonding.
5. Specialized PVC screen printing can also be used for spraying.

[Standard color number and characteristics]
Please refer to the company's standard color cards and color characteristics table.
[How to use and precautions]
1. SPA series products, all kinds of physical properties are very good, the use of special solvents, a very thin plastic film on the PVC has a strong etching effect on the high plastic content of PVC material, there is accelerated plasticizer seepage Maybe, please pay attention to prevent it.
2. Organic colors have high frequency bonding, good physical properties, and strong bonding strength. However, inorganic color should be taken care of. The bonding strength is appropriate. It is advisable to use a suitable amount of SPA oil to adjust the viscosity. If the color density is poor, it should be brushed at two degrees. Strive for absolute benefit.
3. The ink film has the characteristic of tolerant to toluene. Do not use benzene as the diluent for the weak ketone to keep the stability of the ink and the ideal printability.
4. When there are heavy metal control requirements, this product can meet international standards.
