NOVOTEST AP-4219 Peel Adhesion tester

AP-4219 is designed to measure the adhesive strength value of the coatings on different structures, as well as to determine the adhesion value of polymeric insulating tapes which are generally used for pipes insulation.  AP-4219 is reliable and easy in operation.

Advantages of NOVOTEST AP-4219 Peel Adhesion tester

  • Durability of design
  • Easy in operation

Measuring: 

  • samples for testing are tubes with a protective coating of polymeric tapes;
  • adhesion testing is performed at three points at a distance at least 0.5 m from each other;
  • adhesion value of protective coating is characterized with a peel force of insulating strip with defined width;
  • user moves the instrument through a pipe, peel off a undercut strip on a length of 100 mm, measure the peel force and visually determine the character of disruption (adhesion, cohesive, mixed).

 

Types of disruption:

  • Adhesion character of disruption – exfoliation up to the metal.
  • Cohesive character of disruption – exfoliation up to a gluing lawyer or primer.
  • Mixed character of disruption – the combination of adhesive and cohesive characters of disruption.

 

The adhesion value A, N / cm (kgf / cm) of insulating coatings is determined by the formula –

A = F / b, wherein:

F – peel force, N (kgf);

b – width of peelable tape, cm.

 

The value of peel adhesion of the insulating coating is the arithmetic average of three measurements.
