Not for specification purposes Features: Applications * 300 LSE "Hi-Strength" Acrylic Adhesive provides very high bond strength to most surfaces, including low surface energy plastics. * Extremely smooth, non-fibred adhesive for excellent graphic appearance. * Excellent bond to plastics and low surface energy coatings such as, polypropylene and powder coated paints, combined with high shear for excellent temperature resistance. * Excellent adhesion to surfaces contaminated lightly with oil typically used with machine parts. * 94 g/m Polycoated Kraft liner for lay flat, moisture stability and excellent processing of plastic graphic overlays. * Plastic nameplates or graphic overlays for use on low surface energy plastics. * Waste removed nameplates on a common sheet for ease of application. * Graphic application to surfaces such as wood, fabric, plastic, where very high bond strength is required. * Bonding a variety of foam substrates to metal and plastic surfaces. * Attaching identification material to oily surfaces typical of machine parts. 2 Date : July 2000 Laminating Adhesive 9472LE Properties and Performance Bond Build Up The bond strength of #300LSE "Hi-Strength" Acrylic Adhesive increases as a function of time and temperature, and has very high initial adhesion. Humidity Resistance High humidity has minimal effect on adhesive performance. No significant reduction in bond strength is observed after exposure for 7 days at 32C and 90% relative humidity. U.V. Resistance When properly applied, nameplates and decorative trim parts are not adversely affected by exposure. Water Resistance Immersion in water has no appreciable effect on the bond strength. After 100 hours at room temperature, the high bond strength is maintained. Temperature Cycling Resistance High Bond strength is maintained after cycling four times through:4 hours at 70C 4 hours at -29C 16 hours at 22C Chemical Resistance When properly applied, nameplate and decorative trim parts will hold securely after exposure to numerous chemicals including oil, mild acids and alkalis. Temperature Resistance The #300LSE "Hi-Strength" adhesive is usable for short periods (minutes, hours) at room temperatures up to 148C, and for intermittent longer periods of time (days, weeks) up to 93C. Low Service Temperature - 40C (Not for specification purposes) Adhesion Properties Not for specification purposes Peel Adhesion - (Newtons/10 mm) ASTM D3330, modified: 90 Peel, 51 micron aluminium backing. 15 minute dwell room temp. 72 hour room temp. N/10mm N/10mm Stainless Steel ABS Polypropylene Processing 11.9 11.2 12.6 15.3 14.0 14.9 Slitting & Die-Cutting: This adhesive is very aggressive and may be difficult to die cut. Chilling the adhesive to between 2C and 10 C will improve the processability. In addition, dies can be lubricated with Laminoleum evaporative stamping oil Roll Laminating: A combination of metal and rubber rollers with moderate pressure is recommended. Note: Please refer to the 3M Slitting/Die-Cutting Technical Bulletin for further details. 3 Date : July 2000 Laminating Adhesive 9472LE Special Considerations For maximum bond strength the surface should be thoroughly cleaned and dried. Typical cleaning solvents are heptane or isopropyl alcohol. Consult solvent manufacturer's Material Safety Data Sheet for proper handling and storage instructions. Bond strength can also be improved with firm application pressure and moderate heat, from 38 C to 54 C, causing the adhesive to develop intimate contact with the bonding surface. Ideal tape application range is 21 C to 38 C. Initial tape application to surfaces at temperatures below 10 C is not recommended for most pressure sensitive adhesives because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is generally satisfactory. 3M is a trademark of the 3M Company.
