3M SP7533 3kg Screen Printable Adhesive Waterborne Pressure Sensitive Glue for Industrial Printing

Product Overview

3M™ Screen Printable Adhesive SP7533, 3 kg is a waterborne emulsion adhesive designed for screen-printing applications. The official 3M product page lists the product as 3 kg, 4 Can/Case. Once dried, the adhesive cannot be re-emulsified, making it suitable for forming a stable adhesive coating in precise printed areas.

SP7533 can be applied like ink using standard screen printing equipment. After drying, it forms a pressure-sensitive adhesive coating that bonds on contact. 3M’s technical bulletin describes it as a water-dispersed, high-solids formulation that helps improve coverage, reduce adhesive waste and support complex or high-volume applications.

Key Features

• Waterborne emulsion screen-printable adhesive
• Cannot be re-emulsified once dried
• Suitable for stainless steel, polyester or nylon screen mesh; stainless steel is generally used for thicker coatings
• Designed for adhesive printing work and precise pattern coating
• High-solids formulation; 3M technical information indicates approximately 65% solids for high coverage
• Helps reduce adhesive waste by applying adhesive only where needed
• Supports complex printed adhesive patterns and tight dimensional designs
• Water-dispersed technology and non-flammable in the wet state
• Good peel strength, shear strength, aging properties and elevated temperature resistance
• Suitable for bonding polycarbonate and other plastics, metal and more

Typical Applications

3M SP7533 3kg is suitable for industrial applications requiring precise adhesive placement, complex pattern coating, selective adhesive printing and high-volume production.

Typical applications include:

• Membrane switch keypads
• Instrument control panels
• Graphic overlays
• Home appliance components
• Audio equipment
• Pagers and mobile phone components
• Automotive interior trim
• Foam padding

Storage and Handling

Storage Recommendations

• Keep the product in its original sealed container.
• Close the lid tightly after use to prevent skin formation on the adhesive surface.
• If slight separation appears in the upper layer after long-term storage, stir well before use.
• Avoid adding additives such as defoamers, as they may reduce adhesion.
• Do not return dried adhesive back into the container.
• Store away from heat, acids and strong bases.

Handling and Use Recommendations

• Use the adhesive directly from the container without dilution.
• When using waterborne adhesives, select water-resistant masking material for the screen mesh.
• Select screen mesh based on the desired coating thickness and printing precision; 3M’s application guide recommends 70 to 150 mesh for printing SP7533.
• Avoid breathing mist, vapors or spray. Avoid contact with eyes, skin and clothing.
• Do not eat, drink or smoke while using the product, and wash thoroughly after handling.
• This product is intended for industrial and occupational use only, not for consumer sale or use.
• Avoid release to the environment and use personal protective equipment such as gloves or respirators as required
