Said to be ideal for a variety of automotive, aerospace and oil & gas sector applications, DELOMONOPOX HT760 is a high temperature, heat-cured anhydride adhesive. It boasts a high bond strength after long-term aging (1,000 hours at 250oC) and at temperature (also 250oC), as well as having good temperature stability and thermal and chemical resistance.
Eamonn Redmond, sales manager, commented: “Many applications now require adhesives that can survive high temperatures and still bond well. In the oil & gas sector, for example, product extraction temperatures can be over 200oC. And in the automotive sector, several fluids are used which can compromise bond integrity.”
In tests, DELOMONOPOX HT760 demonstrated a bond strength (compression shear strength on ceramics) of 43MPa when tested at room temperature. After 500 hours at 250oC, cooling and subsequent increases in temperature the test results were: 52MPa at room temperature, 15MPa at 200oC, 12MPa at 220oC and almost 10MPa at 250oC. Also, in compression shear strength tests - FR4 on FR4 after 20 minutes of curing at 150oC, subsequent cooling and exposure to typical automotive fluids - the following results were produced: 47MPa for diesel, 44MPa for petrol and 43MPa for ATF gear oil.
Unlike most specialist adhesives for harsh environment industrial applications, DELOMONOPOX HT760 can be ordered in minimum order quantities as low as 200g; supplied as four 50g syringes. Redmond notes: “All adhesives have a finite shelf life, so ordering large quantities can prove wasteful in the long-run. At Inseto, our philosophy is one of Total Customer Service, and we are committed to working with all customers to understand their processes and supply them with made-to-order adhesives in suitable quantities and at optimum intervals. Also, our relationship with DELO is such that we frequently get involved in specifying changes to the chemistry of some adhesives for bespoke applications.”
