What are the reasons for the color difference of silicone protective film

06 Sep 2019

The application of silicone protective film is more pure silicone protective film and composite PET protective film.Recently, shenzhen customer "has been puzzled by the color difference of silicone protective film".What are the reasons for the color difference of the silicone protective film under the inventory of KANGLIBANG silica gel color paste manufacturer?First understand the composition of silicone protective film.PET substrate, silicone glue layer, color paste composition.The color of the protective film mainly comes from the silica gel masterbatch or silica gel color paste.Its PET material and organic silicon material are colorless and transparent, so the effect on color difference is 0.Due to the different color system of color paste and color master, its fluorescence color is the least temperature resistant, temperature limit is about 130℃, other color system can withstand 180 to 200℃.

KANGLIBANG specializes in producing masterbatches and pastes for silicone rubber and silicone resin.It can avoid direct use of toner is not easy to weight, color deviation and poor dispersion defects.KANGLIBANG silica gel masterbatch is an indispensable organic silicon material for the production of high-grade silicone rubber and silicone resin products.

KANGLIBANG silica gel color paste features:

1. Stability: imported brand raw materials are used for color masterbatch and color paste to ensure high stability of color hue, color light, brightness and saturation.

2, easy to disperse: in the process of color masterbatch and color paste processing using strict refining technology and with excellent dispersant, so that in the very low hardness of the rubber has excellent dispersion.

3, high temperature resistance: the high temperature resistance of the pigment is much higher than the silicone rubber molding temperature (175℃), special specifications after a long time of secondary vulcanization (200℃*4 hours), the color change is very small.[the temperature tolerance limit of fluorescent series is 130℃]

4. Comprehensiveness: there are various varieties and complete colors. According to the color matching principle of three primary colors, colors covering all visible spectra can be produced.The company can also develop and customize color masterbatch for customers with special requirements.

5, the whole product series: conlibon color masterbatch and color paste has general use silicone rubber masterbatch, food grade silicone rubber masterbatch, liquid silicone rubber color paste, silicone resin color paste and other series products, suitable for different USES of customers.

What is the difference between silica gel color masterbatch and silica gel color paste?Which works?

Silica gel color paste and color masterbatch are silica gel colorants, different is the state, color masterbatch is solid, color paste is liquid.Which one is better depends on the field of application.Among them, the color paste is suitable for molding or condensation type liquid silica-pet protective film/silicone gel (chest pad), glass fiber silicone resin, two-component silica gel (label glue), etc.Other silica gel molding products generally choose silica gel color master.
