At the initial-stage of understanding the customer’s required performance properties our Adhesive Representatives cover this partial checklist: a. What is the product’s function and the specific polymer usage therein? b. What are the specific substrates to be bonded? c. What mechanical forces, shock & vibration will the assembly be subjected to? d. What is the maximum service temperature range and normal operating temperature range for the component? Is it subjected to any thermal shock or cycling? e. Will the bond be exposed to any chemicals or sterilants? f. Do you need to meet any specific standards or approvals such as USP Class VI biocompatibility, FDA food grade, NASA low outgassing, or UL94V-0 flame retardant g. Are there any required optical characteristics? h. Do you require specific thermal and/or electrical properties? i. Are there specific viscosity requirements? j. What are the manufacturing constraints cure time, personnel, occupational safety etc. k. What mixing, dispensing and curing equipment do you already have? Do you have any surface preparation equipment?
