Fuller Automotive Company 31601 Research Park Drive Madison Heights, MII 48071 Dear Mr. Secor: This is in response to your letters and telephone conversations with members of my staff and the Office of Hazardous Materials Technology asking if an adhesive with the proper shipping description "Self heating, solid, organic, n.o.s., 4.2, UN 3088," formulated as either PG II or PG Ill, is subject to the requirements specified in the Hazardous Materials Regulations (49 CFR Parts 171-180) when placed between automotive parts and offered for transportation on racks with no outside packaging. You stated the adhesive is applied to provide structural support to the parts before they are cured. You provided the following additional information: the parts are large metal assemblies such as rear tailgates, doors, hood decks, and fenders used predominantly on mini vans and small utility vehicles. 2. a maximum amount of 2.6 ounces of the adhesive is placed around the outer periphery of the parts in a 16-foot long continuous bead that is 3 mm wide and high, and the parts are sandwiched together. 3. the parts are cured in an oven at 300°F to 350°F. 4. the maximum temperature developed on the surface of the parts when they ! are cured is 300°F to 350°F. The answer is no, the adhesive no longer meets the definition of a Division 4.2 material in the packaging and transportation scenario described. Thank you for your inquiry. If we can assist you further, please contact us. Sincerely, Hathe a mitchell Hattie L. Mitchell, Chief Regulatory Review and Reinvention Office of Hazardous Materials Standards •#

REMARKS: Urgent For your review • Reply ASAP Please Comment Dear Mr, Secor: I presented your questions about how to test your adhesive as a Division 4.2 in the packaging your automotive manufacturing customers use, that is sandwiched between automotive parts as part of the metal curing process. One of our chemists, Dr. Charles Schultz, asked me to ask you the following questions. He said the information in the file you provided is not sufficient to information on: base an opinion as to whether these parts should be regulated. He said we need more detailed 1. What types of parts are involved? 2. How much adhesive is applied to the parts? 3. What is the curing temperature? 4. What is the maximum temperature developed on the surface of the parts when they are cured? If you wish to discuss these issues with Dr. Shultz directly, his telephone number is (202) 366- 4545.

A synopsis of our discussion follows: 1. What types of parts are involved? Answer: Large metal assemblies such as rear tailgates, doors, and mini vans and small utility vehicles. hood decks, and fenders used in the automobile industry -- - predominately on 2. How much adhesive is applied to the parts? Answer: Worse case, a maximum of 2.6 ounces of adhesives would be extruded around the periphery of a part and then sandwiched between overlapping metal sheets: Bead is 3mm wide and high by a maximum continuous length of 16 feet. Parts are then put in a rack to await fabrication. 3. What is the curing temperature? Answer: Actual parts with adhesive are cured in an oven at 300°F to 350°F. This generally occurs during; the cycle used to cure (dry) freshly applied paint.#

Answer: 300° to 350°F during the paint cure cycle. Although curing can take place very slowing at ambient temperatures, the large quantity of metal in an assembly dissipates heat as rapidly as it is formed so there is no noticeable surface temperature rise. Dr. Schultz and I are both in agreement that the situation described here and in my presides coresponded pes any hazard in reparation and the assembles would be Eileen, we would like to get this resolved; as always, we thank the Department for its help.

INTRODUCTION • This report summarizes the results of a series of experiments performed by Dust Tech, Inc., Augusta, New Jersey, for H.B. Fuller Automotive Products, Inc., of Madison Heights, Michigan, under Purchase Order No. F18517. Contact with H.B. Fuller Automotive Products, Inc., was maintained through Mr. ene Seacore. Self-heating evaluations of two samples were conducted using the UN Test Method (14.3.4) to determine UN packaging class (4.2). IL. MATERIALS Two samples were submitted, which were tested as received. These were identified as "WC2290B" and "WC2390", epoxy adhesives; WC2290B was blue, and WC2390 was gray-green. III. DESCRIPTION OF EXPERIMENTS UN Test Method for-Self-Heating Substance The principle of the method (14.3.4) is to keep samples in stainless-steel screen cubes at constant temperature for 24 hours, making observations as to whether the temperature of the sample exceeds 200°C. (This test method is a godification of the Bowes-Cameron cage test, a self-heating test method for carbon.) The test procedure is performed in a hot air circulating-type oven (Blue M) with an inner volume of 12-15 liters, capable of controlling the internal temperature at 140°C * 2°C. Cubic sample containers with 2.5-cm and 10-cm sides, made of 0.15" : stainless-steel wire screening with a mesh opening of 0.53 mm (28 mesh), -1-#

Page 16P. OUS -.. DTI Report 2539 H.B. Fuller Automotive Products, Inc. with the top surface open, are used. Each container is housed in a cubic container cover made from 0:4-mm stainless-steel wire screen with a mesh • opening of 0.595 mm (26 mesh) and slightly Targer than the sample container, so that the container fits in this cover. In order to avoid the effect of air circulation, another stainless-steel cage, made from D.4-mm wire screen with a mesh opening of 0.595 mn (26 mesh) and 15 cm x 15 cm x 25 cm in size, is further installed to house the covered sample container. Stainless-stee1-sheathed thermocouples of 1/8" diameter are used for temperature measurement. One is placed in the center of the sample and : another between the sample container and the oven wall. The temperatures are measured continuous y. The sample powder or granulate (in the commercial form), is filled to the brim of the sample container, and the container tapped several times. If the sample settles, more is added. If the sample is heaped, it is leveled to the brim. The container is housed in the cover and hung at the center of the oven. : The oven temperature is raised to 140°C and kept there for 24 hours. The temperature of the sample is recorded. 1 The first test is conducted with the 10-cm cube sample. Observations are made to determine 1f spontaneous ignition occurs or if the temperature : of the sample exceeds 200°C. If negative results are obtained, no further testing is necessary. If positive results are obtained, a second test is conducted with a 2.5-cm cube sampie to determine the data for packing group assignment. • - 2-#

Sample WC2290B. yielded temperatures in excess of 200°C in the 10.0-cm cube but not in the 2.5-cm cube configuration. VI. SUBSTANCE CLASSIFICATION A substance should te classified in Division 4.2 if, in the first test using the 10-cm cube sample, spontaneous ignition occurs, or the temperature of the sample exceeds 200°C during the 24-hour testing time. Packing groups are assigned as follows: (a) Packing Group II is assigned to substances which give positive results when tested with the 2.5-cm cube sample. : • • - 3-#
