The test method of pressure-sensitive adhesive consists of the following steps: Prepare 100mL, 10% trimeric anhydride trihydroxy resin sample solution. Use a clean rubber scraper to remove oil from the adhesive surface of the adhesive tape. Wipe with alcohol or ethanol 10 times and dry the adhesive surface with a hair dryer. The tape is […]
Hot-melt adhesive and water-based adhesive are two different adhesives. Hot melt adhesive is a kind of adhesive that can be bonded after heating to a certain temperature. It mainly uses polymers as raw materials and can be bonded to various materials after melting by heating. For example, hot melt adhesives can be used to repair […]
Silicone pressure-sensitive glue around mainly includes polysiloxanes and organosilanes, the following are some common examples: The patch used after surgery, such as an anti-adhesion agent, is mainly composed of medical grade polyoxyethylene siloxane polymer, colorless and transparent, with strong adhesion, air permeability, water resistance, drug resistance, chemical corrosion resistance, and anti-adhesion. The main components of […]
Hot melt adhesive and pressure sensitive adhesive are two different adhesives, and their use and effect are different. Hot melt adhesive is a plastic adhesive, usually used to stick wood, paper, fabric, and other materials. It can be heated to melt, then applied to the surface that needs to be bonded, and finally cooled to […]
The methods to test the initial adhesion of pressure-sensitive adhesives include the initial adhesion test, the stick holding test, the temperature resistance test, the thermal indentation test, the anti-stripping property test, etc. The initial viscosity test can be tested using the “zhi” word method, the specific steps are as follows: Cut a small slit in […]
