serilor®HR1 & HR3 High Resistance |
|
|
| serilor®HR1 & serilor®HR3 - High resistance squeegees : for use with industrial & UV inks that require optimal abarsion & chemical resistance. Available in white color, in most profiles and dimensions, in single, double & triple durometer. |
| | serilor®HR is a special polyurethane blade with exceptional combined resistance to chemicals and abrasion. It was developed to withstand the toughest applications in screen printing and to have a long shelf life in most environments. serilor®HR blades are manufactured with a centrifugation process to avoid bubbles and craters in the material and to bring optimal homogeneity to the compound, even at the core of the material and after grinding. Our exclusive computer controlled casting process guarantees batch to batch consistency. Each serilor® HR blade is inspected for edge quality and profile. |
| ADVANTAGES :
- Maximum resistance to chemicals
- Maximum resistance to abrasion
- High environment stability (temperature, humidity)
- Sharpens well
- Individual package protects from light and dust
- Individual batch & reference ink jet marking on blade
- High test inspection for aspect defects
| APPLICATIONS :
- Graphics multi-purpose
- Graphics specialities (electronics, industrial etc....)
- Object / Container printing
- Automated textile printing
- Manual or automatic equipment use

| | INSTRUCTIONS : In general softer grades (65sh) are used for increased ink deposits and high coverage printing. Harder grades (85sh) are used for reduced deposits, notably when printing UV inks for fine texts and higher line counts.Do not apply excessive pressure on squeegees as this makes your ink deposit heavy and uncontrollable and creates excessive wear. It is recommended that your squeegee slightly exceeds the printed image in size, and to leave significant free space between your screen edge and both squeegee ends. Gently insert the squeegee in a machine or hand holder. Use appropriate squeegee thickness to avoid forcing the blade in the holder. If the holder construction allows for it, regularly change the printing side of the squeegee to minimise the effect of bending with speed and pressure. Rotate your squeegee : do not wait until mechanical & chemical wear bents permanently back your blade to replace it by a fresh one and allowing it to relax, flat, for up to 24 hours. • Cleaning Remove excess of ink with a cardboard or a soft cloth. Wash blade with an impregnated cloth or in an appropriate cleaning machine. Avoid the use of aggressive chemicals, in particular ink thinners.Let the squeegee rest and the chemicals evaporate before re-use or sharpening. • Sharpening
serilor® HR squeegee blades can be sharpened by all methods commonly used in the screen printing industry
(Fimor offers an extended range of diamond wheel sharpeners, please contact us for more informations).
- Belt grinders
- Wheel sharpeners
- Knife cutting machines
Sharpen dry squeegees only. Never allow a squeegee with solvents to be sharpened and don’t wash a hot, freshly sharpened blade with chemicals. Do not try to grind excessive material in one pass.Precision printing requires a preventive sharpening to accomodate the squeegee edge to the holder shape. • Storing / Shelf life :
For all medium or long term storage, blades must be kept flat, unrolled, especially prior to use. Store in a dry cool place away from any direct source of light. If the squeegee is exposed to extreme temperature and humidity conditions, its hardness characteristics may be altered. |
