What is the effect of the roughness of the adhesive Velcro on its viscosity_

There are two reasons for the bonding strength of general adhesive hook and loop. One is the effect of surface treatment, and the other is the roughness of the surface. The appearance treatment before bonding is the key to successful bonding, and its intention is to obtain a robust and durable joint. Due to the weakened layer composed of oxide layer, plating layer, phosphating layer, release agent, etc. on the material to be adhered, the surface treatment of the adherend will affect the bonding strength. For example, the surface of polyethylene can be treated with hot acid oxidation to improve the bonding strength. When heated to 70-80°C for 1-5 minutes, an excellent bondable surface will be obtained. These two conditions will directly cause the Velcro to stick. The connection strength is affected. This method is suitable for polyethylene plates, thick-walled pipes, etc. If it is carried out at the above temperature, the surface treatment of the film will adopt plasma or micro flame treatment.

When the adhesive excellently moisturizes the surface of the material to be adhered, the roughening of the surface is conducive to the moisturizing degree of the traveling adhesive liquid on the surface, increasing the density of the contact point between the adhesive and the material to be adhered, hook and loop wholesale factory. Then Conducive to the advancing bonding strength. On the contrary, when the single construction glue does not moisturize the material to be adhered, the roughening of the appearance is not conducive to the progress of the bonding strength.
