Cohesive Force This kind of removable adhesive wall hook is commonly used at home. But how can the little adhesive wall hook hold 1kg or even heavier stuff? The secret is the cohesive force of the adhesive glue. We have talked about the adhesion force of the glue in the last article. Besides the adhesion
Adhesion Force One day, a clerk in the shop tried to tag labels on merchandise. Have you ever considered why the labels can be affixed well on the goods? One of the important secrets in the glue is Adhesion Force. What does the adhesion force of the glue mean? Adhesion force is the attraction strength
What is the Initial Tack? One of the important properties of a pressure-sensitive adhesive is the initial tack. When talking about initial tack, we refer to the strength of a material’s stickiness when an adhesive first comes into contact with the surface to which it is to be glued. Tack helps us measure how
What is a Good Adhesive? An adhesive that meets a client’s needs is a good adhesive. We believe that only your imagination can limit the applications of adhesive. There are many types of adhesives but few manufacturers can work the way Chemix Guru does. We work closely with our clients, listen to their demands, and

Why Is Adhesive Sticky? According to the record, Egyptians used natural glue made from animal collagen since 5000BC. In modern times, we use glue to stick things together. Have you ever wondered what is the secret inside? Behind the Stickiness of An Adhesive To put it briefly, Adhesive is sticky because of the interaction of
Sticky Note Adhesive To manufacture sticky notes, there are thousands of adhesives you can choose in the adhesive industry. However, not all of them may meet the purpose of manufacturing sticky notes. You may refer to the article “why adhesive is sticky”. Each adhesive is designed to provide different performance to meet its application and
Applications of Label Adhesive Label adhesive is one of the most popular adhesives in Chemix Guru’s product line. However, label adhesive is not as simple as its name suggests. There are actually several different kinds of label adhesives and we would like to provide several tips to help each of our clients find the right
PUR Adhesive VS EVA Hot Melt Adhesive Many of our clients may ask us what’s the difference between the PUR adhesive and traditional EVA Hot melt adhesive? Both are hot melt adhesives; their features may sound similar. However, according to the manufacturing process, the theory of chemical reaction, and performance, they are actually different types
After reading “What is PUR adhesive”, you may have a general idea about PUR. In this article, we would like to introduce to you more knowledge about PUR and its laminating PUR machine. The Operating Process of PUR adhesive At room temperature, PUR is present as a solid block. Before starting the laminating process,
Solvents for PU and PSA Adhesive What is a Solvent? Solute + Solvent = Solution A solvent is a component that dissolves other solutes into a solution. For example, water is a kind of solvent for polar substances and the most common one used in our daily life. Today we are going to talk about
What is PUR Adhesive? PUR adhesive, also called Polyurethane Reactive (PUR) Hot Melt Glues, is 100% solid content, isocyanate (NCO) capped adhesive. PUR will contact the moisture in the air, and allow it to form stronger bonds after the curing process is completed. PUR is highly flexible, has strong adhesion, and is suitable for a
Adhesive is around us, even in the clothes we are wearing every day. ChemixGuru provides a wide array of fabric lamination adhesives that fits your every need.
What is Acrylic Adhesive? Acrylic adhesive is a kind of acrylic polymer prepared by different kinds of acrylate monomers, like 2-Ethylhexyl acrylate and butyl acrylate, by using semicontinuous emulsion and solution polymerizations. When the acrylic polymer is synthesized to a certain molecular weight range, it will become sticky and adhere when pressure is applied, as
1. The difference between acrylic adhesive and polyurethane adhesive 2. What is polyurethane adhesive, and what are its applications? 3. What are the benefits and applications of polyurethane adhesive? Polyurethane Adhesive Provides Permanent Adhesion Compared with acrylic adhesive, polyurethane (also called PU) adhesive provides extremely strong adhesion, isolation, and flexibility. Therefore, you can find that
What is Viscosity? Viscosity is a measure of a liquid’s resistance to flow, which describes the internal friction of a moving fluid. In the observation, low-viscosity adhesives will flow more readily than high-viscosity ones. For example, water has a much lower viscosity than honey and adhesive, so the water will flow easily and quickly because
This question can be divided into two parts. The first part is the introduction of polar and non-polar molecules, and the other part is an introduction of some common non-polar materials.
