3M™ Masking Tape 203 is a rubber adhesive that provides good instant adhesion that sticks to a wide variety of surfaces and reduces time and effort needed to run down. Ideal for good holding power to help resist lifting or curling. Crepe paper backing that is conformable to maintain integrity when formed around a corner. Backing resists slivering yet exhibits easy, hand tearability. Backsize treatment provides easy, controlled unwind. Ideal for good paint hold-out that resists bleed-through. Can be certified for ASTM-D6123/D6123M97. Replaces obsolete PPP-T-42C, Type 1, (CID-A-A-883A).
Typical physical and performance characteristics include: thickness: 4.7 mils, adhesion to steel:28 oz../in. width, tensile strength: 22 lbs./in. width, elongation at break: 8%, temperature use range: Up to 200(deg)F. Tan.
