Tensile strength of adhesive bonds

Evaluation of bond strength of adhesive with metal surface is of atmost importance in many applications. An estimation of this adhesion strength is measured by this test method. This testing is used for applications with many adhesive systems and primers.

AD1ME-1	Tensile Properties of Adhesive Bonds	D897-08

Lap shear test

Lap shear testing is adhesion test which very frequently specified by many manufacturers, automotive, aerospace and electronic industries and so on, which is very critical property to establish the strength of intended application. Metal specimens in identical strips are prepared the adhesive is applied on the defined overlapping portion. The test facility for performing Lap shear testing for Adhesives is available at Maeon Laboratories.

90° 180° Peel adhesion test

90°.180° Peel adhesion testing is performed on many Pressure Sensitive tapes such as Electrical insulation tapes, double side tapes, masking tapes, duct tapes, packaging tapes, bandages tapes, tapes for medical devises, tapes for industrial application. The types of test procedure under this method is followed by Maeon Laboratoriies as customer standards.

T-Peel Test

The Peel resistance of adhesives are testing in Maeon Laboratories using the T Peel testing method using Test method given below. The precision testing device separates the coating and substrate apart and measures the force required to peel apart.

Loop Tack Strength

Adhesive tapes, adhesive films, sticker labels all have a coating of pressure sensitive adhesive applied on to it. Its initial tack or stickiness is an important property for its application. Maeon laboratories have facility for testing the tack force or tack strength using precision test equipments.

Double lap shear test

The double lap shear test method for adhesives produce shear property data for adhesives for bonding metals which are essentially peel-free.

AD1ME-26	Standard Test Method for Strength Properties of Double Lap Shear Adhesive Joints by Tension Loading	D3528-96

Shear test by Compression

The shear strength property of adhesive obtained compression mode is evaluated. Shear strength value obtained is a measure of adhesive strength, primarily for Wood-to-wood , wood to lumber and other construction materials.

Floating roller peel adhesion test

The tests uses a laminated or bonded adherends, where one adherend is made to be rigid and the other adherend is made to be flexible. The test is conducted by peeling of the flexible adherend rom the rigid adherend at a controlled angle of peeling. Maeon laboratories have facility for the Floating Roller Peel strength testing.

AD1ME-24	Floating Roller Peel Resistance of Adhesives	D3167-10

Pull off force measurement of Adhesives

For many applications Adhesives require to be tested for its Pull off force, which test is performed at Maeon laboratories

Shear strength by pin and collar specimen

Standard Test Method for Shear Strength of Adhesives Using Pin-and-Collar Specimen. This test method covers the determination of the shear strength of curing liquid adhesives used for retaining cylindrical assemblies or for locking and sealing threaded fasteners.

Torque strength of adhesives for Threaded fasteners

Maeon Laboratories provide testing services for Adhesives used for thread locking. The tests determines the torque strength of the securing adhesives used for threaded fastening.

	Torque strength of Adhesives used on Threaded fasteners	D5649-15 ISO 10964

Viscosity of Adhesives

Adhesives specifications provide data on the viscosity, specific gravity and the solid content. These provide an idea of the material properties including molecular weight and density which affect flow behavior. Maeon Laboratories offer testing service on viscosity of Adhesives, using rotational viscometer, which uses a torsion spring to measure the torque required to rotate a spindle in the material. Changing rotor speed and size allows for the measurement of different ranges of viscosity.

Density of Adhesives

The Density of Adhesives in liquid form are tested by Weight-per-Gallon cup method, Maeon Laboratories provide services for testing Density of Adhesives.

AD1ME-17	Standard Test Method for Density of Adhesives in Fluid Form	D1875-03

Tensile Strength and Elongation Properties

Adhesive tapes, label, adhesive films etc. are tested for its physical characteristics such as Tensile strength at break and Elongation properties. They are tested in both Machine direction and Cross direction. Best facilities are available at Maeon Laboratories to perform Adhesive tape Tensile strength, elongation properties.
