Identify color requirements:
First, determine the desired color. This can be done by referring to Pantone color cards, actual samples, or other color references.
Try to avoid selecting colors through pictures sent by electronic devices or pictures taken by mobile phones, as device conversion and lighting brightness may affect color accuracy.
Prepare materials and tools:
Prepare the required liquid silicone base.
Select the appropriate masterbatch (color paste). Depending on the color requirements, multiple masterbatches may be required for blending.
Prepare tools such as high-precision electronic scales, scrapers, mixers, and color mixing containers.
Calculate and adjust the masterbatch ratio:
Based on the desired color, determine the required basic hue and masterbatch ratio through color analysis.
Use an electronic scale to accurately weigh the masterbatch according to the calculated ratio.
Mix and stir:
Mix the weighed masterbatch with the liquid silicone base in a certain ratio. The specific ratio needs to be determined based on the characteristics of the masterbatch and silicone.
Use a mixer to fully stir the mixture to ensure that the masterbatch is evenly dispersed in the silicone. During the mixing process, a small amount of silica gel can be mixed with the masterbatch first, and then gradually added to the barrel and stirred to better dilute the viscosity of the masterbatch.
Comparison and adjustment:
Compare the stirred silica gel with the Pantone color card or other color reference to check whether the color is consistent.
If the color is deviated, it can be adjusted by increasing or decreasing the proportion of the masterbatch until the desired color is reached.
Filtering and storage:
Filter the colored silica gel to remove possible masterbatch precipitation to ensure the quality of the silica gel.
Store the colored silica gel in an appropriate container to avoid contamination and deterioration.
Notes:
During the coloring process, keep the environment clean and dry to avoid the influence of impurities and moisture on the silica gel.
Liquid silica gel and color should be mixed at room temperature and avoid operation in high or low temperature environments.
When adding color, the pigment needs to be fully absorbed and dispersed by the silica gel to avoid discoloration.
Through the above steps, the desired liquid silica gel color can be quickly and accurately adjusted. It should be noted that color matching is a process that requires experience and skills, and requires constant trial and adjustment to find the best color ratio. If you choose Hongtu liquid silicone and order a certain amount, you can get free color matching and mix various colors according to your needs.
