3 High Performance Industrial Plastic Adhesives 4693 4693H Technical Data January, 2017 Features 3M High Performance Industrial Plastic Adhesive 4693: low viscosity grade for spray or brush application. 3M High Performance Industrial Plastic Adhesive 4693H: high viscosity grade in collapsible tubes for flow applications. Clear, elastomeric adhesives with high immediate bond strength, long tack range and contact bond properties. Exhibit outstanding bond strength to many metals and many plastics such as ABS, glass filled polyester, polypropylene, linear polyethylene and hi-impact styrene. Dries to a tough, flexible and transparent film with good resistance to water and aging. Note: Not recommended for use on plasticized vinyl. Use on plasticized vinyl may result in poor adhesion or bonds that deteriorate over time. Typical Physical Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.

For best results, temperature of adhesive should be at least 65F (18C). Application Porous Surface: Brush, spray or flow an even coat of adhesive to both surfaces. Very absorbent materials may require more than one coat. Bond while adhesive is tacky. Join surfaces with firm pressure. 3M High Performance Industrial Plastic Adhesives 4693 4693H Handling/Application Non-Porous Surface: Brush, spray or flow an even coat of adhesive to both Information (continued) surfaces. To achieve a satisfactory bond, adhesive must be force dried 180F (82C). Bond with firm pressure while warm. Drying Time: Drying time depends on temperature, humidity, air movement and porosity of the materials bonded. When brushing, wait a minimum of 10 minutes. Bonds can be made up to 60 minutes. Sprayed bonds may be made almost immediately and up to 60 minutes. Heat Reactivation: Adhesive may be heat reactivated by raising the glueline temperature to 180F (82C). Cleanup: Excess adhesive may be removed with a solvent such as 3M Solvent No. 2.* *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturers precautions and directions for use. Note: Appropriate application equipment can enhance adhesive performance. We Application Equipment suggest the following application equipment for the user s evaluation in light Suggestions of the user s particular purpose and method of application. 1. Pumping: A 2:1 divorced design pump is suggested. All material hoses should be nylon or PVA lined. Packings and glands in contact with the adhesive should be PTFE lined. 2.
