Kohesi Bond manufactures first-rate adhesives, sealants, coatings, potting and encapsulation compounds that offer sensational mechanical strength properties. Our highly dedicated team of engineers research and develop custom-made products that meet your specific end-requirements. These products are frequently used in the electronics, semiconductor, optical, medical, aerospace, automotive, oil and gas and specialty OEM applications. Our products are capable of meeting various industrial certifications, like NASA low outgassing (ASTM E-595), USP Class VI, ISO 10993-5, halogen free and UL 94 V-0 flame retardance. In addition, they maintain high bond strength at extreme temperatures (including cryogenic) as well as withstand harsh chemicals.
Tensile strength refers to a material’s ability to resist breaking when pulled apart (under tension). The tensile strength of an epoxy is measured using the ASTM D638 test method, which involves casting an epoxy in a specified shape and then pulling it under tension at a fixed rate. The point at which it breaks, measures the products ultimate tensile strength. Kohesi Bond manufactures high tensile strength epoxy adhesives that offer strength of greater than 11,000 psi. These extremely strong one and two component adhesives offer reliability, durability and ease of use. They can be tailored to meet specific requirements.
Compressive strength refers to a material’s ability to resist breaking under compression (being pushed together). The compressive strength of an epoxy is measured using the ASTM D695 test method. This method involves casting the epoxy and applying a steady compressive load. The breaking point gives the material’s compressive strength. Kohesi Bond formulates specialty high compressive strength epoxy adhesives that offer strength of more than 20,000 psi. The compressive strength properties depend on the type of resin-curing agent system and the filler used. We can customize our formulations to meet exact specifications in your application.
Shear strength refers to a material’s ability to resist breaking under a shearing force. The lap shear strength of an epoxy adhesive is measured using the ASTM D1002 test method. This test method involves bonding two aluminum strips in a specified area, using the epoxy adhesive to be tested. Then the two aluminum strips are pulled apart under a constant load. The point at which the two strips debond, gives the tensile strength of the epoxy adhesive. Choice of resin, curing agent and filler affect the strength properties of the epoxy. In addition, surface preparation is absolutely crucial in achieving good adhesion. Kohesi Bond can custom formulate adhesives capable of offering shear strength of more than 3,800 psi. Our high shear strength epoxy adhesives offer excellent adhesion even at extreme service conditions.
Peel strength refers to a material’s ability to resist breaking under a peeling force at a predetermined angle. The peel strength of an epoxy is measured using the ASTM D1876 test method. In this test method, two aluminum sheets are bonded in a specified area, using the adhesive to be tested. After the two sheets are completely bonded, they are peeled under a constant load at a specified angle. The force at which the two sheets steadily peel out, measures the peel strength of the adhesive. Kohesi Bond manufactures superior one and two component epoxy adhesives that offer phenomenal peel strength. Our high peel strength epoxy adhesives hold up to extreme service conditions while maintaining good strength.
Flexural strength refers to a material’s ability to resist deformation under load. The flexural strength of an epoxy is measured using the ASTM D790 test method. This test method involves casting the epoxy adhesive in the specified shape and dimensions. Following that, the cured casting is placed on two supporting points and a constant load is applied from the top (third point). The point at which the material fails in known as its flexural strength. This test is also known as the three point bending test. Kohesi Bond formulates epoxy adhesives with first-rate flexural strength. They adhere well to similar as well as dissimilar substrates. In addition, they can hold up to extreme temperatures, harsh chemicals and other severe service conditions.
Cleavage strength measures the ability of the adhesive to resist breaking when it is being pulled from one point. The cleavage strength of an epoxy is measured using the ASTM D1062 test method. This test method involves bonding two metal substrates using the adhesive to be tested. The cured, bonded specimen is then pulled at one point. The point at which it debonds is known as the cleavage strength of the adhesive. Kohesi Bond manufactures high cleavage strength epoxy adhesives. Our first-rate products hold up to their electrical, thermal, chemical resistance, acoustic and strength properties under severe conditions. These adhesives can be customized specifically to your requirements.
