AF 30 (5, 10 and 12 mil) Introduction 3M™ Scotch-Weld™ Structural Adhesive Film AF 30 is an unsupported, thermosetting film adhesive developed for structural bonding of metals and high strength plastic laminates (epoxy and phenolic). Some of the advantages of Scotch-Weld AF 30 are:

• High shear strength.
• High peel strength.
• Excellent flexibility and toughness.
• Can be pressure, heat or solvent tacked in position.
• Excellent retention of strength after aging in many environments.
• Excellent adhesion to most metals including aluminum, titanium, stainless steel, cadmium, nickel, brass and others (Must use high pressure).
• Extremely low flow. Technical Data June, 2002

AF 30 (5, 10 and 12 mil) - 2 - The following product performance data has been obtained in the 3M Laboratory under the conditions specified. All data reported in this section except as noted, were developed under a cure cycle using 150 psi (1.034 MPa) bonding pressure applied by a platen press. A 200°F/minute (111°C/minute) bond line temperature rise from 80°F to 350°F (27°C to 177°C) with 60 ± 1 minutes at 350° ± 2°F (177° ± 1.1°C) was used. A. Aluminum to Aluminum Overlap Bonds The following data show typical values obtained with 3M™ Scotch-Weld™ Structural Adhesive Film AF 30 (5 mil) in aluminum overlap bonds. All properties were measured on 1" wide (25.4 mm), 1/2" (12.7 mm) overlap specimens cut from .063" thick 4" x 7" (1.600 mm thick 101.6 mm x 177.8 mm) bonded panels of 2024-T3 clad aluminum.

AF 30 (5, 10 and 12 mil) - 8 - Product Application Surface Preparations A thoroughly cleaned, dry, grease free surface is essential for maximum performance. Cleaning methods which will produce a break-free water film on metal surfaces are generally satisfactory. Suggested Cleaning Procedure for Aluminum 1. Alkaline Degrease – Oakite 164 solution (9-11 oz/gallon water) at 190°F ± 10°F (87.8°C ± 5.6°C) for 10-20 minutes. Rinse immediately in large quantities of cold running water. 2. Optimized FPL Etch Solution (1 liter): Ma terial Amount Distilled Water 700 ml plus balance of liter (see below) Sodium Dichromate 28 to 67.3 grams Sulfuric Acid 287.9 to 310.0 grams Aluminum Chips 1.5 grams/liter of mixed solution To prepare 1 liter of this solution, dissolve sodium dichromate in 700 ml of distilled water. Add sulfuric acid and mix well. Add additional distilled water to fill to 1 liter. Heat mixed solution to 66 to 71°C (150 to 160°F). Dissolve 1.5 grams of 2024 bare aluminum chips per liter of mixed solution. Gentle agitation will help aluminum dissolve in about 24 hours. To FPL etch panels, place them in the above solution at 150 to 160°F (66 to 71°C) for 12 to 15 minutes. 3. Rinse – Rinse panels in clear running water. 4. Dry – Air dry 15 minutes; force dry 10 minutes (minimum) at 140°F (60°C) maximum. 5. It is advisable to coat the freshly cleaned surfaces with primer within 4 hours after surface preparation. Note: Read and follow safety and precautioning recommendations for the components of this etch solution prior to preparation. Primer Application Advantages– Priming of adherends offer two distinct advantages: (1) insures complete wetting of metal surfaces which normally results in superior environmental properties, and (2) simplifies production by protecting cleaned parts until bonding can be completed. Primers have been applied successfully by flow coating, brushing and spraying. For additional information, please refer to the 3M™ Scotch-Weld™ Structural Adhesive Primer EC-1660 (5%) Technical Data sheet. Primer Dry A primer dry which will result in a solvent free coating is generally satisfactory. Drying temperatures above 300°F (149°C) should be avoided, since a primer overcure will hinder the wetting action of the adhesive film to the primer. The following chart lists suggested dry cycles for primers: Air Dry Force Dry Force Dry Temperature Scotch-Weld EC-1660 30 minutes 30 minutes 225°F (107°C) The primed surface, after cooling to ambient temperatures, is ready for adhesive bonding. The primed surface should be protected from contamination introduced by dust, fingerprints, oil, etc. Film Application Care should be taken to avoid contaminating adhesive and cleaned or primed aluminum by any substance which will hinder wetting action of the adhesive. 1. Cut portion of film to be used from roll with protective liner in place. 2. Place film on metal using the liner as a protective cover. 3. Roll film into position with a rubber roller insuring that no air is trapped between primer and film.

AF 30 (5, 10 and 12 mil) - 9 - Product Application (continued) 4. Remove protective liner. 5. Assemble parts and cure. Excess primer and equipment may be cleaned up, prior to curing, with ketone* type solvent. *Note: When using solvents, extinguish all ignition sources and follow manufacturer’s precautions and directions for use. Cure Cycle General Cure Requirements Time, temperature and pressure determine the final bond properties and may be effected by the type of curing equipment used for each specific application. In general, the cure properties of 3M™ Scotch-Weld™ Structural Adhesive Film AF 30 are as follows: Tack, Flow and Cure Initiation Temperatures The tack, flow and cure initiation temperatures for Scotch-Weld AF 30 are a time-temperature relationship and depend upon the rate of heat input. Normally, Scotch-Weld AF 30 has the following properties: Tack Temperature: 160°F-180°F (71°C-82°C) Flow Temperature: 180°F-220°F (82°C-104°C) Cure Initiation Temp.: 220°F-270°F (104°C-132°C) Cure Pressure Pressure is required during cure to form the part being bonded and contain any volatiles given off by the adhesive. Cure pressure may be applied in any matter which will insure uniform constant pressure throughout the bond area. Pressure must be uniformly applied before the curing reaction begins and maintained until a complete set has been effected. (i.e., the bond line temperature has reached approximately 300°F (149°C). After this point is reached, the cure may be completed without pressure if the hot strength of the adhesive is sufficient to maintain contact of the parts being bonded. The pressure required to contain volatiles is dependent on the rate at which bond line temperature is brought to the cure temperature. The bond line temperature rise rate for Scotch-Weld AF 30 can be varied from 1°F to 300°F/minute (0.6°C to 166.7°C/minute). Rise rate (and cure pressure required) will depend on application, cure temperature, bonding equipment, method of heat application, production limitations and bond properties required. Figure I depicts typical pressure required for various bond line temperature rise rate in platen presses. Bond Line Temperature Rise Rate Cure Pressure (psi) 50°F/min (27.8°C/min) 100°F/min (55.6°C/min) 150°F/min (83.8°C/min) 200°F/min (111.1°C/min) 250°F/min (138.9°C/min) 300°F/min (166.7°C/min) 300 250 200 150 100 2,067 1,723 1,378 1,034 689 344.5 Cure Pressure (KPa) Figure I Cure Pressure vs Bond Line Temperature Rise in Platen Presses

AF 30 (5, 10 and 12 mil) - 10 - Product Application(continued) Cure Temperature The cure temperature may be varied from 250°F to 450°F (121°C to 232°C), depending upon the materials being bonded, equipment available and bond properties desired. The desired pressure must be applied before the glue line reaches 160°F (71°C). The film will soften as temperature is increased to 180-210°F (82-98.9°C) and will wet the surface to which it has been applied. A chemical cure will be initiated between 220°F and 270°F (104°C and 132°C) and a low strength gel formed. Continued heating chemically converts this gel into a high strength, solvent resistant bond. 3M™ Scotch-Weld™ Structural Adhesive Film AF 30 will change color only slightly upon application of heat. Edges of the bond which are exposed to air will change from yellow to rusty brown. Cure Time Cure time depends on the cure temperature used, methods of heat application, production limitations and bond properties required. Since no two bonding operations are exactly alike, it is suggested that a few simple experiments be conducted, varying both temperature and cure time to determine optimum conditions for the particular application. Figure II is a guide from which an approximate cure cycle can be taken for various cure times or temperatures. 300°F (149°C) Cure Time (Minutes) Cure Temperature A.

Apply a pressure of 100 psi (689 MPa) prior to reaching a bond line temperature of 150°F (66°C) and maintain throughout the press cure cycle. 2. Raise the bond line temperature from ambient to 350°F (177°C) at a rate of 10°F-12°F (5.6°C-6.7°C) per minute. 3. Cure for 60°F ± 1 minute at 350°F (177°C). 4. Cool to below 200°F (93°C)/bond line temperature prior to release of pressure. (In lab tests, panels have been removed at 350°F (177°C) with no adverse effects.)
