The viscosity of the adhesive can also be a significant factor in adhesive selection. Low — viscosity adhesives (<50 mPa-s) should be used where gaps are small and the adhesive is required to flow or wick into parts that have been pre-assembled. A medium — viscosity adhesive (up to 1000 mPa-s) may be more appropriate for the bonding of, say, cylindrical parts where the diametral gap is of the order of 0.1 mm. High-viscosity adhesives (>10,000 mPa-s) would be specified for larger gaps or where the adhesive is required not to flow away from the joint prior to assembly and cure.
