Silicone Roller Coatings

Roller manufacturers who have transitioned to CHT’s flowable RTV-2 silicone elastomers have experienced many process advantages. CHT’s liquid silicones can be pumped at much lower pressures and time is reduced when filling moulds compared to using gum stock or paste materials.

Additionally, CHT’s liquid silicones are easily processed when used with sleeves or in applications requiring thin roll coats. These silicones also rebound instantaneously and do not take a set if the proper cure profile is followed.

Features and Benefits of CHT’s silicone solutions:

  • No knit lines resulting in seamless roller production and minimized defects in finished rollers and the end product
  • Excellent machinability and grindability
  • Customisable cure time to meet different production requirements
  • Low viscosity for ease in processing
  • Low compression set
  • Wide selection of durometer specifications from 20 to 80 (Shore A)
  • Good chemical resistance
  • Thermally conductive grades available
  • High operating temperature up to 260°C

Applications benefitting from CHT’s silicones include:

  • Photocopy rollers
  • Laser printer rollers
  • Photographic imaging rollers
  • Printing rollers
  • Currency dispensing rollers
  • Film and microfilm rollers
  • Magnetic tape capstans
  • Medical chart recorder rollers
  • High-speed mail sorting rollers
  • Cleaning (sticky) rollers
  • Medical imaging rollers
