Tips for the best results with LINGBAO pearl pigments in the paint industry
Jul 31, 2018

1. Dosage/loading

Pearl pigment dosage is determined by many factors, such as its coating thickness, the method it’s applied, its transparency, and the surface area to be covered and the final pearl effect. In general, a sufficient dosage is 5 - 10% in weight. Sometimes, a weight of just 1% can produce a beautiful transparent and sparking effect. For thin coatings, the dosage should be increased to around 20 - 30%. Be warned, too many pearl pigments doesn’t guarantee that the platelet-shaped effect pigments will be aligned evenly to the surface and will have their full optical effect.

2. Pre-wetting, dispersion and stirring

Pre-wetting the pearl pigments with solvent or binder components usually makes it easier for dispersion and the best way is to make it into slurry to avoid foam coming out while stirring. To keep a consistent colour shade and avoid flocculating, optimal length of time for pre-wetting is 24 hours.Pearl pigments are easy to disperse and normal stirring is sufficient, so never use high shear machines, which will destroy the pearl pigment platelets and reduce or totally lose the pearl effect. 

3. Methods to improve hiding power of pearl pigments:

a. Small particle size can improve hiding power, but one can only get a silky gloss effect with no shining. To get the ideal pearl effect and hiding power, you can choose to add some small particle sizes instead of using all big particle sizes.

b. Adding metal powder to the ink can improve its hiding power (like Aluminum powder, bronze powder) and the dosage of pearl pigments should be about 5 - 10%.

c. To formulate dark colours, a small proportion of carbon black can improve the hiding power and also enhance the reflection colour of pearl pigments.

d. To formulate lighter colours, TiO2 (Titanium Dioxide) will be helpful to strengthen the hiding power. But, since it is not good for pearl effects, you will need to use more pearl pigments to enhance the reflection colour. The best way is to use as little TiO2 as possible to reach the best hiding effect.

Note:  Non-transparent or dye will reduce the pearl effect.

At -home devices: from multi-functional to multi-technology

Mirroring the trend for multifunctional products in beauty, the latest at-home devices now combine more than one technology. Ewa Grigar, project lead, Kline highlighted 2016 innovations in this area:

?Strialite targets stretch marks with a device that combines LED and heat which is claimed to reduce their appearance.

?Beauty Bioscience’s Glo Pro is the first company to use micro-needle technology combined with Red LED technology to exfoliate and brighten the skin.

?Illuminage Beauty’s Me Clear Anti-Blemish Device comprises tri-action technology of blue light, sonic vibrations and heat.

?Sonulase Age-Defying Light Brush uses anti-ageing Red light with powered cleansing and UV light to kill bacteria.

Kline has noted a trend towards mini devices which claim to be as powerful and effective as the full-size versions. For example, Clarisonic Mia Fit is a mini version of the legendary Mia cleansing brush, and Forea’s Luna Play is a small sonic face cleanser that claims to last for up to 100 full cleansing routines and is positioned as an affordable introduction to the T-Sonic?. There are also anti-ageing minis, such as Patchology Energising Eye Patches with micro-current technology, that come with an activating gel, and the Me Eye Illuminating Device that combines Red LED light with radio frequency.

Many of the above innovations showcased at the Marketing Trends presentations have the potential to change beauty routines around the world. Only time will tell which of them will succeed.
