$Effect of mass fraction of silane coupling agent on properties of lotion and film$

2020-10 28

Effect of mass fraction of silane coupling agent on properties of lotion and film
Self emulsifying PU introduces hydrophilic groups into the PU molecular chain. Silane coupling agents disperse PU molecules in water to form a stable dispersion through the hydrophilicity of the hydrophilic groups. Polyamine groups react with residual isocyanates to expand the chain. The silicon oxy

Principles for selecting silane coupling agents
Among the two types of functional groups with different properties in silane coupling agents, the Y group is the most important, which directly determines the application effect of silane coupling agents. Only when the Y group can react with the corresponding matrix resin can the adhesive strength o

What are the usage methods and dosage tips of silane coupling agents
1. The surface pretreatment method involves preparing a dilute solution of silane coupling agent with a concentration of 0.5-1%. When in use, simply apply a thin layer on the clean surface to be adhered, and after drying, the adhesive can be applied. The solvents used are mostly water, alcohol, or a
