11、 The adhesive shall be a smooth, homogeneous mixture, free from foreign materials. The material must be adaptable for application in accordance with the appropriate Ford Motor Company Process Specification and compatible with all related materials. 4. GENERAL INFORMATION The information given below

12、is provided for clarification and assistance in meeting the requirements of this specification. 4.1 STORAGE STABILITY 12 months The material must be stable during storage at temperatures between 5 C and 32 C. 4.2 RECOMMENDED OPERATION TEMPERATURE 170 - 180 C 4.3 DEGRADATION POINT 190 C If the temper

13、ature of the adhesive exceeds the degradation point, the adhesive will decompose and all physical properties become adversely and permanently affected. The material is not to be used once the degradation point has been exceeded. 4.4 OPEN ASSEMBLY TIME 60 s(At an operation temperature of 170 - 180 C) Open assembly time is the maximum time interval from initial application of the adhesive to the completion of the part assembly for bonding.
