Hot weather in the summer, the use of hot melt adhesive is often due to temperature changes, hot melt adhesive manufacturers often recommend the use of hard hot melt adhesive in summer, so why use hard hot melt adhesive in summer and soft hot melt adhesive in winter? I'm sure many customers have such doubts. Suitable for hot melt adhesives in summer, related to the characteristics of hot melt adhesives. Hard hot melt adhesive, its softening point is relatively high, can withstand high temperature. It is often said that after finishing the glue, the operator who uses the hot melt adhesive says that the glue does not stick, the glue is very thin, the drying is slow, and even if the glue has dried, it is easy to remove the adhesive part. Hot melt adhesives such as Summer three volts soften significantly compared to normal temperatures. Hot melt adhesive manufacturers often introduce two different formulations of hot melt adhesive products to handle the same type of hot melt adhesive application in different temperature weather.
Hard hot melt adhesives have a high natural softening point. When glued, the rubber layer is less susceptible to high temperatures and softens, resulting in a decrease in cohesion. These are the glue quality that hot melt adhesive manufacturers themselves need, and there is a quality standard responsible for the customer. Use a small amount of hot melt adhesive in summer and a softer hot melt adhesive in winter. This is not only the manufacturer of hot melt adhesives, but also the users of hot melt adhesives have a certain understanding of this aspect. This is avoided because the hot melt adhesive is not well selected, which leads to problems with the product.
Of course, there are exceptions. It is not necessary to use hard-stemmed hot melt adhesives in summer. Some stable hot melt adhesives can also meet the requirements of summer use.
