Squeegees

Fimor. Serilor SR1 and SR3

serilor®SR1 & serilor®SR3 - Universal color coded squeegee blades. Available in most colors, profiles and dimensions in single, double and triple durometer. serilor®SR squeegee is an all purpose polyurethane blade with good combined resistance to chemicals and abrasion. It was developped to withstand various applications in screen printing. The industry standard S1 is a universal grade, your ideal choice for non critical abrasive application or when using common screen inks. serilor®SR 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® SR blade is inspected for edge quality and profile.

    STANDARD HARDNESSES:
    soft 65shA red medium 75shA green hard 85shA blue 60,70,80,90 and other durometers are available as specials, Other colors on request.

    Serilor®SR3 TRIPLE LAYERS:

    MARKING : serilor®SR3 length X width X thickness Profile hardness [batch N°] MADE IN FRANCE

    STANDARD COMBINATIONS:
    Triple medium 75/90/75 shA Green/White/Green Triple soft 65/90/65 shA Red/White/Red
    Recommended when high speed automatic printing equipment is used, serilor® SR3 has a 90shA hard centre layer for support, ideal for fine lines and halftone printing. Using Triple durometer squeegees will extend your squeegee life, help prevent dot gain, and generate immediate savings on ink and other consumable through better control of the squeegee pressure.

    P5: Double Bevel (V type) for SR1
    P6: Single Bevel for SR1
    D: “Diamond” square profile for SR1

    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® SR 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.
