Loop Adhesion Tester LT-3000

Application of Loop Adhesion Tester: LT-3000 Primary Adhesive Tester, compact and sophisticated in structure, using top quality central componets, is applicable in testing primary adhesive force of kinds of tapes, adhesives and other different products. It meets FINAT( FINAT TESTMETHOD NO. 9: LOOP TACK MEASUREMTN), ASTM and other international standards, suitable for university, technical secondary school, quality inspection administrative authority, adhesives import and export enterprise, inspection and quarantine bureau.

Operational principles of Loop Adhesion Tester: The loop tack value of a pressure sensitive material is expressed as the force required to separate, at a special speed(300mm/min), a loop of material (adhesive outermost) which has been brought into contact with a specified area of a standard surface.
A tensile tester or similar machine with reversing facility and a vertical jaw separation rate of 300mm per minute. It should also have a capability of measuring direct loads up to at least 20Newtons.
A flat plate made of float glass or equivalent plate glass measuring 25±0.5mm x 30±2.0mm x minimum thickness 3.0mm. A metal peg is attached the centre of one face of the plate. The dimensions of the peg should be such that the peg can be clamped in the lower jaw of the tensometer.
