Adhesives are widely used in People’s Daily life, providing a variety of conveniences for people’s life. Pressure Sensitive Adhesive (PSA) is a very important adhesive. Psa is very sensitive to pressure and can be strongly bonded to the adhesive by applying mild pressure without the need for solvent, heat, or other means. Since the last […]
With the development of industrial science and technology, the need to paste the substrate from traditional wood, paint, metal, and other materials, gradually developed into the plastic substrate, plastic substrate compared with metal, wood, and other materials easy to process, but the surface energy is low, difficult to bond. The existing use of rubber series […]
Example 1: 50 parts of methyl hydrogen silicone oil with hydrogen content of 3mmol/g and viscosity of 100cp at 25℃, 60 parts of toluene and 0.5 parts of Karstedt catalyst were added to the reactor equipped with mechanical stirring, thermometer, reflux condensation tube, drip funnel and nitrogen protection device. The temperature was heated to 120℃ […]
