Sure, but it depends on the purpose. If it is to adjust the color of the adhesive layer (such as using a specific color adhesive for the inner lining of a gift box), a legitimate manufacturer blends the color masterbatch with the base material before granulation to make uniformly colored particles; It is not recommended for users to add color powder randomly on site, as it may cause uneven dispersion and affect performance.
| Points to note | Explanation |
|---|---|
| compatibility | The color masterbatch should be in the same system as the base material, otherwise it will affect the bonding |
| dosage | Excessive pigment will weaken the cohesive strength |
| uniformity | Blending granulation is far superior to on-site mixing |
Q: Will colored glue affect the adhesion strength?
Answer: Regular customization is basically not affected, only adding color powder randomly.
Q: Can we customize colors for small batches?
Answer: Sunlife hot melt adhesive can be color matched according to the sample, and Guangzhou Sunlife commercial and trade partners can provide samples.
Q: Can transparent adhesive be made?
Answer: Yes, the low yellowing formula is suitable for transparent/light colored bonding.
Specific color adhesive is required. Please contact Guangzhou Sunlife Trading to obtain Sunlife hot melt adhesive color scheme and samples.
First of all, the conclusion is that the powder on gold and silver cardboards is mostly due to “surface coating not being treated properly” or “glue temperature not being pressed down” Gold and silver cardstock is coated with a layer of gold and silver foil or PET aluminum plated film on the surface of the […]
The aging of hot melt adhesive is mainly manifested in two aspects: appearance and performance. Visually, the color of hot melt adhesive may become dull, and even yellow or brown tones may appear. The texture may become hard and brittle, losing its original flexibility, and the surface may have cracks or fissures. In terms of […]
1) hot melt adhesive for cartons is a common adhesive used in the sealing of boxes and cartons. 2) This is about sealed flaps. The application of adhesive is usually the end process of the production line and involves applying the adhesive at high temperatures to open the fins, and then bringing the fins into […]
The aging of hot melt adhesive is quite common in its application. This phenomenon is mainly caused by the glue heating time being too long or the heating temperature being too high. How to determine if hot melt adhesive has aged? Aging hot melt adhesive may exhibit the following phenomena: 1、 Glue discoloration; 2、 There […]
