Conditions for Successful Adhesive Attachment

1. SUITABLE SURFACE

2. CLEAN & DRY

3. ATTACHMENT PRESSURE

4. BOND TIME

1.Suitable Surfaces - Includes most non-porous materials including fiberglass, metal, rigid plastics, hardwood finishes (lacquer or varnish), and glass. Not intended for use on copper, brass, or rough and porous surfaces such as unfinished wood, concrete, or fabrics.

2.Clean & Dry- All surfaces for fastener attachment must be clean and dry. Use Alcohol Pads provided or isopropyl alcohol (rubbing alcohol) even if surface appears clean. Do not substitute alcohol with household cleaners or detergents!

3.Attachment Pressure- The bond strength of the adhesive is dependent upon the amount of adhesive-to-surface contact developed. Firm pressure when attaching fasteners develops better adhesive contact and thus imporves bond strength. A screwdriver or similar tool is helpful for pressing down on fastener for stronger attachment that is possible by hand. Note: The adhesive cannot bond if there is tension that is pulling it away from the fastening surface. Wait a minimum of 4 hours after attachment before closing fastener locks on straps or testing fasteners for holding strength (lifting or pushing equipment).

4.Bond Time- At room temperature the adhesive will bond to approximately 50% of its ultimate strength in 20 minutes, 90% after 24 hours and 100% after 72 hours. IMPORTANT: There is risk of damage when adhesive is applied to wall board, paper wall coverings or fabrics. Always test for desired results before using on questionable surfaces. THE ADHESIVE IS NOT INTENDED FOR USE TO HOLD OR SUPPORT WEIGHT ON VERTICAL SURFACES. It should be used as a holding restraint on horizontal surfaces in accordance with recommended use, installation instructions, for the size and number of fasteners used

Holding Strength- The holding performance of Thumb Lock fasteners is subject to the variables of the installation. These include the size and number of fasteners used, how and where they are attached, the size, shape, weight and center of gravity of the item being fastened, the material and condition of the fastening surface, the frequency and duration of heavy weight loads on the fasteners, and other factors. The WEIGHT RANGE CHART below shows the weight range of four different size Thumb Lock fasteners using adhesive attachment in two-corner and four-corner configurations. The holding values used are typical values and should be used as guidelines only. If your are not confident the fasteners you have are strong enough for the application, attach and test one of them for holding strength on the surface they will be used, waiting at least 24 hours for the adhesive to bond. To add holding strength, you will need additional or larger fasteners, screw-fix attachment, or both. Also, restraining movement at the top of the equipment with tether straps or additional fasteners will help to secure tall, top-heavy equipment. (Fig. E below).

Chart is for low profile, wide-base equipment. Reduce by 50% for tall, top-heavy equipment.
