Characteristics of Acrylic Polyurethane Topcoat Acrylic polyurethane paint, formed by the reaction of hydroxyl-containing acrylic ester and aliphatic polyisocyanate such as HDI trimer, has a paint film with excellent hardness and flexibility, and good chemical resistance. Its outstanding weather resistance, high gloss, good drying properties, and fast surface drying without dust adhesion make it t...
Polyurethane materials are a general term for a class of macromolecular compounds that have urethane structures in their molecular structure. They are usually prepared by the polyaddition reaction of diisocyanates and polyols. Polyurethane polymers possess both polar functional groups that allow for physical cross-linking and non-polar and flexible chain segments. When used properly, these po...
The Secret to Non-Peeling Labels: How Adhesives Determine Label Lifespan In everyday packaging, label peeling is a common yet troublesome problem – not only affecting product appearance but also potentially raising consumer doubts about quality. But have you ever considered that a crucial science lies behind this: adhesives? Adhesives: The "Invisible Guardians" of Labels Adhesives a...
One component of self-adhesive label materials is the adhesive, also known as glue. The adhesive determines the label's stickiness and applicable scenarios. The adhesive is also the bonding layer between the label and the object it's applied to; its stickiness, temperature resistance, and magnetic adhesion directly affect the label's adhesion effect. It can be divided into the following categories...

01 Polyurethane The structure of polyurethane is formed by the reaction of polyisocyanates (e.g., diisocyanate OCN-R-NCO) and polyols (e.g., diol HO-R-OH), where urethane segments are repeating structural units. Polyurethane structures have structures similar to amide and ester groups; therefore, the chemical and physical properties of polyurethane are between those of polyamides and polyesters. S...
Many people find themselves torn when selecting materials: since both are used for coatings, which one offers greater durability? Which is the more suitable choice for waterproofing during renovation? In reality, neither possesses an absolute advantage over the other; the key lies in the specific requirements of the application scenario. Today, we will clarify the core distinctions between the two...
Water-based varnishes are classified as eco-friendly products; the primary solvents used in their formulation are water and various alcohols, ensuring that their volatile components do not pollute the environment. The development of water-based varnishes has gained momentum in recent years, driven by the growing public demand for environmental protection. The process of applying varnish essentiall...
For coating and surface material applications, product performance depends on many real production factors. Laboratory testing is important, but actual customer feedback can provide more direct information about coating process, substrate condition, curing performance, adhesion, abrasion resistance, and final surface quality. Recently, the Sinograce Chemical team completed overseas customer visits...
When choosing coated work gloves, customers often focus on grip patterns, coating color or glove thickness. However, the performance of a dipped glove also depends greatly on the latex material used in the coating formulation. A good coating should remain attached to the knitted liner, bend easily with hand movement and withstand repeated contact during daily work. If the coating is too rigid, the...
