3M industrial adhesive 4799 provides a reliable bond for EPDM and rubber applications. Resistant to heat and water, this industrial adhesive delivers the durability you need and can depend on for years to come. 3M industrial adhesive 4799 delivers a tough bonding solution that provides resistance to both heat and water. We formulated our industrial adhesive 4799 to be a brushable adhesive, capable of establishing a strong, flexible bond that will stand the test of time. Whether it is being sprayed, brushed or rolled on, the application of your 3M adhesive is a straightforward process. Start by carefully applying your adhesive to your surface until you've formed a uniform coat. Using an overlapping pattern, the application of one coat should prove sufficient for most surfaces. Some substrates, including porous materials, may require an additional coat. In order to apply additional adhesive, simply wait until the existing adhesive becomes dry to the touch and then proceed with the application of the additional coat.
