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...
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...
Environmental Friendliness: Water-based acrylic resins use water as a solvent and do not produce harmful gases or pollutants during use, meeting environmental protection requirements. Weather Resistance: They have good weather resistance and can be used under various climatic conditions, being less susceptible to the effects of ultraviolet light, oxygen, and humidity. Good Adhesion:...
This seemingly ordinary milky-white liquid contains immense power to transform the world of materials. In daily life, we rarely notice a chemical product called "acrylic emulsion," yet it's ubiquitous—from home wall coverings to clothing fibers, from packaging materials to wood coatings, this magical emulsion is quietly adding color and convenience to our lives. What is Acrylic Emulsion? Acrylic e...
Acrylic resins used in adhesives and acrylic resins used in coatings differ in the following aspects: Performance Characteristics Acrylic Resins for Adhesives High Bonding Strength Requires strong adhesion between different materials, requiring rapid curing and sufficient cohesive and adhesive strength. For example, α-cyanoacrylate adhesives can cure in seconds for rapid bonding. Good Flexibility ...
1. Excellent Adhesion The polymer structure of water-based acrylic emulsion facilitates the flow and wetting of molecular chains on the substrate surface, resulting in close contact between the coating and the substrate molecules, achieving high adhesion. 2.High Pigment and Filler Loading Capacity, Significantly Reducing Costs Water-based acrylic emulsion has excellent filling properties...
