How can fabric surface treatment improve silicone adhesion?
Cleaning and Decontamination: Use an organic solvent such as alcohol or acetone to wipe the fabric surface to remove impurities such as oil, dust, and release agent. This ensures a clean surface, enhancing contact area and adhesion with the silicone. For example, when treating synthetic fiber fabrics such as nylon and polyester, this cleaning method can effectively improve subsequent bonding.
Roughening: For smooth fabrics such as polyester or PVC-coated fabrics, physical abrasion (e.g., light sanding with sandpaper) or chemical etching (e.g., using a mild acid or alkaline solution of appropriate concentration for a short period of time followed by rapid rinsing) can increase the surface roughness, thereby improving the mechanical bond between the silicone and the fabric. However, be careful to control the degree of treatment to avoid excessive damage to the fabric's properties.
Silicone Surface Treatment
Cleaning and Degreasing: Use a dedicated silicone cleaner to remove impurities and substances such as silicone oil from the silicone surface, ensuring a clean surface. Plasma Treatment: Using plasma to treat the silicone surface can alter its chemical properties and microstructure, increasing surface active groups and raising its surface energy, thereby enhancing its adhesion to fabrics.
