1. Pearlescent Artificial Leather

With the improvement of people's living standards, the application of leather is more and more extensive. However, due to the protection of animals, natural leather is limited in quantity and expensive. With the development of science and technology, synthetic leather (artificial leather) is increasingly used to replace natural leather. Its performance is very close to that of natural leather, but it is much cheaper than leather and has a wide range of uses. In addition, it can be mass-produced, so it plays an increasingly important role in people's daily life. From clothes, handbags, boxes and shoes to furniture and upholstery, artificial leather can replace natural leather almost everywhere. In recent years, pearlescent leather is a kind of artificial leather coated with pearlescent pigments, which is very popular and can be seen everywhere in life.

2. Pearl Pigment for artificial leather coating

Pearl pigment is widely used in the coating of natural and synthetic leather. It has obvious pearl luster effect, and it is non-toxic, tasteless, high temperature resist, non-acid, non- alkali, has stable chemical properties. Generally speaking, we can add pearl pigment into ink to get pearlescent ink. We also can add pearl pigment into transparent plastic resin used in the pressing and scratching of pearlescent leather.

3. Tips for using pearlescent pigment

Since pearlescent pigments (pearl pigment) rely on the reflection of light to produce pearlescent luster, the resins, pigments and other fillers used with them are required to have high transparency. Opaque or high hiding power pigments and additives, such as titanium dioxide, will weaken the pearlescent effect, so they must be avoided with pearlescent pigments. But in specific circumstances, it can be added in an appropriate amount to increase the hiding power of the pearlescent film. Pearlescent pigments are used in the form of imprint inks; the dosage is approximately 15% of the total amount of printing ink. To be mixed in resin and get pearlescent changes, the consumption is about 2%-5%. If the transparency is low, the amount of pearlescent pigment can be increased or adopt big particle sized pearl luster pigment.

6. FAQ & solution

Q: How to improve if the pearly luster effect is not enough?

A: 1) Check if you have added strong hiding power of pigment and filler. If yes, modify formula.

A: 2) Check if the dosage of pearl pigment is appropriate; Too much or too less will both bring poor pearl effect.

A: 3) Check if the particle size of pearl pigment matches with the line and carve depth of the printing cylinder. Contact with iSuoChem sales team to get guidance of technics.

A: 4) Check if the transparency of solution is weak or the membrane is not very well, and the surface luster is not enough. If yes, we recommend you to use better printing ink instead.

A: 5) Check if pearl pigment powder is dispersed very well in solution. The gathered particles will influence the pearly luster effect.
