Adhesives
A wide array of adhesives is used as a bonding agent/coating agent for various metallic, paper and plastic components. They need to be tested for adhesion, viscosity etc. before a product is used for intended requirement. Laminates, electronic devices, medical devices, packages, building materials uses liquid adhesives, tapes, sealants etc. which requires quality checks i.e. adhesion, bond strength, peel strength etc. to confirm their end use suitability.Heavy industries especially automobile industries need to understand the static and fatigue behaviour of critical parts where adhesion is applied. Hence measurement of stiffness and strength of adhesive joints between rigid to rigid parts and rigid to flexible parts becomes prime importance. Cyclic environmental testing of such a parts is very important. Defence ammunition requires specialized adhesives which are generally based on shellac, bitumen, nitro-cellulose & various polymers. Considering their criticality they have their own specific test requirements. Our laboratory is pioneer in carrying out testing such as strength, stiffness, lap shear strength, peel strength, cyclic corrosion test & salts spray test. We carry out such evaluation of Ammunition Protective Compositions (APCs) critically to know their suitability for end use requirements.. Adhesives also requires chemical assessment tests such as Acidity, Alkalinity, Drying time, volatile matter, Ash, iodine value, etc. .We have facilities of testing these tests
