CONSIDERING A WIPER

Wipers are used for cleaning large surface areas containing “critical” equipment. They offer advantages in solvent retention and solvent resistance. In choosing the best wiper for a particular application, we need to consider such factors as cleanliness, abrasion resistance, solvent compatibility and absorbency.

Cleanliness is determined by 1) particle count, which measures the size distribution of extractable particles in a wiper; 2) cleanroom grade, which must be low in extractable non-volatile organic residues. The amount of such residues is determined by extracting the residues from the wiper using ultra-pure Di water, ultra-pure IPA or the solvent being used in the particular cleaning application. 3) the wiper is analysed for the amount of extractable ionic contaminants present, such as salts and minerals. Ionic salt contamination is of concern in the manufacture of critical electronic assemblies.

Abrasion resistance: should be considered as wipers will produce particles depending on the amount of abrasion they receive in use. “Cut-edge” wipers will greatly reduce the particle burden.

Solvent compatibility: keep the cleaning application in mind in choosing your wiper. The wiper must be able to absorb a given solvent and retain the solvent within the fabric of the wiper for a sufficient amount of time without premature release of the solvent.

Absorbency: is critical in wiping applications where softness and non-abrasiveness are essential. Absorbond® contains no surfactants, its absorptive capacity is five times its weight, its density of fibre structure allows for the sorption of liquids through a capillary action that gives a great benefit, particularly cleaning and absorbing oil and grease.
