Chatillon Peel Test Fixtures

TG38 - 90° Peel Fixture:                         

This fixture features a self sdjusting sliding bed for 90° peel tests. The test plate may be moved freely in a horizontal position when the pressure sensitive material is removed in order to maintain a 90° peel angle. Note: The test plate must be provided by the customer. The FINAT standard states that plate glass should be used. If stainless steel or aluminium is used as a substitute, it should be stated with the recorded results.

Applications
Used for peel tests on a wide range of materials including sealing tape, labels, laminated coatings, etc. Measuring peel adhesion at 90° normally gives a lower recorded value than at 180° and allows values to be measured for materials, normally giving paper tear. Peel adhesion is defined as the force required to remove pressure sensitive coated material,
which has been applied to a standard test plate under specified conditions, from the plate at a specified angle and speed. This fixture is similar to that used in tests complying with BS 5350: Part C10 and FINAT test method no.2 (FTM 2) - Peel adhesion (90°) at 300mm per minute.

TG580 - Climbing Drum Peel Test Fixture:

The peel test fixture consists of a flanged drum and flexible loading straps or cables. A drum clamp is used to securely hold the adherent against the face of the drum. The drum is balanced about the axis using counter weights placed diametrically opposed the drum clamp to compensate for the clamp mass. Includes fixture and loading straps.

Applications
Used to determine the resistance of joints to perpendicular peel stresses on the adhesive layer. Applicable to the testing of joints between an outer metal sheet and the core of sandwich assemblies, ex..: honeycomb or other forms of composites. The adherents are seperated steadily by the action of a revolving drum which rotates by the application of a tensile force from the associated testing machine

GF-8 - Circular Face Plates for Adhesives

This fixture has detachable, circular face plates made of hardened steel. A ball socket mounting screw helps keep upper and lower plates parallel and perpendicular to the applied force. Face plate diameter is 75mm (3 in). Includes upper and lower plates.

Applications
Used to determine the adhesive characteristics of sealant, adhesive and mastic by measuring the minimum tensile stress necessary to detach or to rupture the coating.
