Refer to Technical Data Sheets and product literature for more specific technical data. 12 11 Removing paint ­ Scotch-Brite surface conditioning discs remove paint quickly without threat of undercutting the work surface. Landing gear peening ­ 3M TC 330 roto-peen flap assembly imparts a residual compressive stress to the bearing surface. This surface stress strengthens the material, improving resistance to fatigue fracture and stress corrosion cracking. Defect removal ­ Save time and money with 3M Roloc coated abrasive discs for efficient removal of deep scratches and defects. Adhesive removal ­ Scotch-Brite Roloc surface conditioning discs remove adhesive "squeeze out" and excess without threat of work surface distortion. 13 14 For more information and assistance: Contact your local 3M abrasive products distributor or 3M.
