Regarding the viscosity and stickiness of hot melt adhesive, many customers will always ask if your hot melt adhesive is strongly adhesive, which means “sticky”. Without specifying what material to stick, it is not possible to directly determine whether the hot melt adhesive is strong or not. Hot melt adhesive is only suitable or not, and there is no strong or weak viscosity, which is a misconception among many customers in consultation.
Viscosity is the internal friction of a fluid, which is the resistance to relative motion between one layer of fluid and another, i.e. the resistance to liquid flow. It is also an important parameter of hot melt adhesive, viscosity, also known as viscosity, refers to the degree of thinness of hot melt adhesive in its melted state. The lower the viscosity, the better the flowability of hot melt adhesive, the easier it is to produce glue, and the less wire drawing. Therefore, the viscosity is related to the coating, wetting, permeability, and wire drawing phenomenon of the adhesive. When it is clear which specific material to stick to, it is necessary to choose the appropriate viscosity based on the material to be glued and the shape, in order to produce a good bonding effect. As a professional hot melt adhesive manufacturer, Sunlife Hot Melt Adhesive only recommends suitable hot melt adhesives. The more expensive the hot melt adhesive, the better. Suitable hot melt adhesives are the best.
Bookbinding adhesive is a flexible and durable hot melt adhesive used in bookbinding. This combination creates a book that can withstand bending and folding without spine cracking or page pulling. Hot melt adhesive for books and periodicals is divided into book edge adhesive and book back adhesive according to their uses. EVA hot melt adhesive […]

Direct answer: The consumption of adhesive particles is relatively high, and 90% of the problem lies in four areas – excessive setting of adhesive amount, waste caused by improper temperature, equipment leakage, and mismatched selection of adhesive particles. After item by item investigation, most factories can reduce unit adhesive consumption by 15% -30% without sacrificing […]
How to avoid equipment failure caused by carbonization of EVA hot melt adhesive? The carbonization of hot melt adhesive in the hot melt tank is left unattended, which can damage your equipment, have a negative impact on your factory’s productivity, and cause unnecessary downtime. Follow these simple tips to reduce hot melt adhesive carbonization and […]
