Grease must be tested for chemical attack to painted surfaces for applications that come in contact with paint surfaces, ex. E-coat and powder coat. 4.10.2 Resistance to Stress Cracking (FLTM BO 127-03) Note: Not te
10、sted for initial application of this grease. Grease must be tested for resistance to stress cracking when used for additional applications that come in contact with polymers such as PC, ABS, PC+ABS, ASA or acrylic 4.10.3 Elastomer Compatibility, (ASTM D 4289, 70 h, 100 C, DIN 53505, DIN 53504) Note: Not tested for initial application of this grease. Grease must be tested for elastomer compatibility when used for additional applications that come in contact with elastomers. Application specific elastomer should be used for testing instead of a reference elastomer.
