    Speedwell System

Elastomer to coat rollers and sleeves specifically for solvent-less, two-component glue coating. An additive base polymer with non-stick properties that avoids closure of the cells on the outer surfaces during work and maintains the ideal surface tightening value for adhesive coating, guaranteeing uniform distribution and considerable savings on glue.

Roller with steel core and/or Speedwell sleeve with a specially formulated, fibreglass conical base. Polycoat Green coating ground to measurement.
