What is the impact of seasonal environmental changes on the use of adhesives?

The good compounding effect of two-component polyurethane adhesives is related to many factors, and changes in the working environment are also important influencing factors. In other words, with the change of seasons and climate, in order to obtain the ideal compounding effect, it is necessary to make some fine adjustments to the adhesive application process. Simply put, the seasonal and climatic changes affecting the compounding are the changes in the two major indicators of environmental humidity and temperature: specifically, in spring and summer, especially during the rainy season, the relative humidity of the air is relatively high, and can even reach saturation, while in autumn and winter, the air is dry and the humidity is low; in terms of temperature, summer is much higher than winter, and the maximum difference between the two can be

Analysis of common problems and solutions for UV (photocuring) adhesives

1. What are the differences between UV glue and other glues? UV glue initially cures in 1-5 seconds under ultraviolet light, and bonding is completed in 20-30 seconds. After irradiation, it reaches a high strength, meeting the needs of automated production lines; the second-generation acrylic structural adhesive initially cures in 1-10 seconds, but takes 24 hours to reach its maximum strength; room temperature curing epoxy structural adhesive initially cures in 10-120 minutes, and takes 7 hours to reach its maximum strength. 2. Is UV glue toxic? Why does using UV glue cause skin redness and itching? UV glue is a green, environmentally friendly, and economical chemical product. It does not contain any organic solvents and has 100% solid content. It is...

What is UV glue?

UV glue, also known as shadowless glue, photosensitive glue, or ultraviolet (UV) curable glue, refers to a type of adhesive that can only be cured by ultraviolet light irradiation. It can be used as an adhesive, or as a binder for paints, coatings, and inks. UV is an abbreviation for Ultraviolet Rays. Ultraviolet (UV) light is invisible to the naked eye and is a segment of electromagnetic radiation beyond visible light, with a wavelength range of 10-400 nm. The curing principle of shadowless glue is that the photoinitiator (or photosensitizer) in the UV curable material absorbs ultraviolet light upon irradiation and generates active free radicals or cations.

How to choose between silicone color masterbatch and silicone color paste?

Ensure safety and environmental protection. What are the characteristics of food-grade silicone color paste? Essential knowledge points that silicone product manufacturers should know. Do you really know them all? Today, Huachen Baocai editor will share with you again. 1. Characteristic 1: Smell. Food-grade silicone color paste is non-toxic and odorless. If you smell a pungent smell directly with your nose, then the kitchen household silicone kneading pad is for special use. During the epidemic, everyone stayed at home and became kitchen masters, and their cooking skills soared. Among them, there are many chefs who use flour, such as: dumplings, buns, steamed buns, bread, etc.; in addition to flour, making noodles also requires

Which color raw materials are safer and healthier for silicone tableware?

Generally, silicone tableware products are qualified, safe, and healthy. However, to be on the safe side, it is better to choose transparent and colorless ones. The silicone raw material itself is colorless or transparent because it contains fewer chemical components. However, if it is for aesthetics, colored ones can also be chosen. Colored silicone tableware products are colored by adding food-grade silicone color paste to the silicone raw materials. Although silicone color paste chemical components are added, as long as the silicone color paste is qualified, safe, and healthy, it is also a good choice. Using Taike food-grade silicone color paste as the color raw material for silicone tableware products is safer, healthier, and more environmentally friendly. Huachenbao

Why are silicone baby food spoons all colorless and transparent?

Because most silicone baby spoons are made from colorless and transparent food-grade silicone raw materials and food-grade silicone color masterbatches. The handles of silicone baby spoons are colored, but the spoon parts that go into the mouth are colorless and transparent. This reduces the amount of food-grade silicone color masterbatch raw materials used, saving costs, and is safer, healthier, and more environmentally friendly, benefiting the baby's growth. If you are interested in safe and environmentally friendly food-grade silicone color masterbatches, please feel free to contact Huacaibaocai.

How are liquid silicone rubber products colored using silicone color pastes?

The application of colorful liquid silicone rubber products is becoming increasingly widespread. So how do silicone color manufacturers color liquid silicone rubber products? Huachen Baocai will answer this for you. Generally, silicone rubber product manufacturers will choose to cooperate with professional silicone color manufacturers, sending the colorful silicone rubber products to the silicone color manufacturer for professional color matching services. Some will also send the silicone raw materials they use together, allowing the silicone color manufacturer to match the colors according to their needs. After the silicone color manufacturer completes the professional color matching, it will feedback the results to the silicone product manufacturer customer. If the customer thinks it is acceptable and wants to try it, the silicone color paste formula will be provided and...

Customized silicone rubber compound masterbatch exclusive formula

With silicone toys, silicone gifts, silicone tableware, and various other silicone products appearing in our daily lives, people are becoming more and more familiar with silicone products. However, many people may not understand the production process and color matching of silicone color pastes. Today, Huachen Baocai will analyze the color matching principle of silicone composite color pastes for you. Liquid silicone products are made from silicone raw materials and silicone color pastes. The colors of some silicone products are not made by simply adding a single silicone color paste, but by mixing and stirring 3 to 4 silicone color pastes in a certain proportion to form a silicone composite color paste. This is not an ordinary technique.
