Tyco Electronics Corporation Specification RT-1006 300 Constitution Drive This Issue: Issue 2 Menlo Park, CA 94025 USA Date: October 23, 2009 Replaces: Issue 1 Adhesive S-1006 Epoxy, Flexible 1. SCOPE This specification covers the requirements for one type of adhesive for use with heat-shrinkable tubing and molded parts. 2. APPLICABLE DOCUMENTS The specifications and standards listed in Table I underMethod of Tes shall form a part of this specification to the extent specified herein. 3. REQUIREMENTS 3.1 MATERIAL The adhesive shall consist of a 2-part modified epoxy resin. 3.2 PROPERTIES The adhesive shall meet the requirements of Table I. 4. QUALITY ASSURANCE PROVISIONS 4.1 CLASSIFICATION OF TESTS 4.1.1 Qualification Tests Qualification tests are those performed on samples submitted for qualification as satisfactory products and shall consist of all tests listed in this specification. 4.1.2 Acceptance Tests Acceptance tests are those performed on adhesive submitted for acceptance under contract. Acceptance tests shall consist of tests for peel strength, flow and pot life. Other tests may be carried out as often as necessary to insure compliance with all requirements of this specification. 4.2 SAMPLING INSTRUCTIONS 4. 2.1 Qualification Test Samples Qualification test samples shall consist of 90 grams of adhesive. 4 .2.2 Acceptance Test Samples Acceptance test samples shall consist of not less than 30 grams of adhesive from each lot. A lot shall consist of all adhesive from the same production run offered for inspection at the same time. Three specimens, each approximately 3 grams, shall be subjected to each test. 4.3 TEST PROCEDURES Prior to tests, each specimen of adhesive shall be thoroughly mixed for from l to 2 minutes. 4.3.1 Peel Strength Peel strength shall be determined with 1 inch heat-shrinkable tubing, Thermofit NT-FR, and 1 inch heat-shrinkable polyolefin tubing, Thermofit RNF-100.

Heat shall be applied with a HG-501A Thermogun equipped with a A-170-HG reflector and operating at 288 - 343 C (550 - 650 F). The recovered tubing then shall be cooled to 25 3 C (77 5 F). After cooling. the outside of the recovered tubing and the insides of three 1 inch lengths of expanded polyolefin tubing shall be lightly abraded with No. 320 emery cloth and wiped with a clean cloth or paper towel wet with methyl propyl ketone. Three grams of adhesive then shall be evenly spread approximately 0.020 inch thick on the recovered tubing except that a 3/4-inch space the length of the tubing shall be uncoated. The three lengths of polyolefin tubing then shall be placed over the adhesive-coated tubing and shall be recovered as described above. Heat shall be continued for 30 seconds after the tubing recovers. This assembly (Figure lA) shall be cured for 45 minutes in an oven maintained at 121 3 C (250 5 F). After cooling to approximately 110 C (230 F) the tubing shall be cut along one edge of the adhesive-free area, removed from the mandrel, and flattened between 6- x 3 1/4-inch metal plates to form a slab (Figure lB). This slab shall be cooled for 1 hour at 25 3 C (77 5F). A specimen one inch wide (Figure lC) then shall be cut from the center of each double thickness. 4.3.1.2 Procedure The unbonded ends of each specimen shall be inserted in the jaws of a tensile tester which shall be operated at a jaw-separation speed of 2 inches per minute. Readings of peel strength shall be taken at every 1/2 inch of jaw separation after 1 inch initial separation. The average of five readings shall define peel strength. 4.3.2 Flow 4.3.2.1 Room Temperature Three grams of mixed adhesive shall be formed into a compact mass about 1/2 inch high and 1 inch in diameter on a smooth glass surface that has been cleaned with methyl propyl ketone. At 25 3C (77 5 F), the glass shall be placed on edge and shall be marked on a line tangent to the bottom edge of the adhesive. After 10 minutes, the glass again shall be marked on a line tangent to the bottom edge of the adhesive and the distance between marked lines shall be measured. 4.3.2.2 Cure Temperature Following the test of 4. 3. 2. 1, the glass shall be mounted vertically in an oven at 121 3C (250 5F). After 10 minutes, the glass again shall be marked on a line tangent to the bottom edge of the adhesive and the distance between the second and third lines shall be measured. 4 .3.3 Dielectric Strength Two polyethylene films, 6 x 6 x 0.002 inches, shall be coated on one side with a release agent such as Dow Corning 4 Compound or equivalent. Three grams of mixed adhesive shall be spread on the coated side of one of these films as a disk from 1 to 3 inches in diameter. The adhesive then shall be covered with the second coated film and the adhesive and films shall be placed between 6 x 6-inch metal plates. The plates shall be pressed together until the intervening disk of adhesive is from 0.005 to 0.025 inch thick. This assembly then shall be cured for 2 hours in an oven maintained at 95 3 C (203 5F). After curing, the disk of adhesive shall be removed from the assembly, cooled to 25 3C (77 5F), and tested for dielectric strength in accordance with the short-time test of ASTM D 149. 4.3.4 Pot Life Three grams of mixed adhesive shall be conditioned in an uncovered container for 1 hour at 25 3C (77 5F). After conditioning, specimens shall be prepared with this adhesive and tested for peel strength in accordance with 4.3.1. If this document is printed it becomes uncontrolled.
