HH-66 WHITE: Medium bodied, slow setting, PVC cement for cellular PVC. Available in 2, 4, 8 and 16 oz. squeeze containers.
Can be used without Primer on non-pressure systems if local codes permit. NSF listed. Item can not ship via Air freight of any kind. HH-66 dries quickly with a very strong, yet flexible bond. It is not affected by weather and temperature extremes, and is highly resistant to oil, fuel, grease, and many other chemicals. Application is by brush, or roller. Dried films may be reactivated to the tacky state by high heat or solvent.
Tips on Assembling PVC Columns and other Cellular PVC products
After testing various adhesives from various manufacturers, we have selected HH-66 cement as that best product to assemble PVC products. The adhesive is very similar to the what is used for black ABS drain pipe with the main difference being a much longer setting and curing time of about 1 hour at 70 F, or 21 C. The lower curing time allows room for error during the installation process. We also recommend the use of mechanical fasteners for the installation of heavier columns or components. Once the glue has cured, the parts become fused as one and will not come apart.
HH-66 cement is recommended only for PVC to PVC, not PVC to any other surface. To adhere PVC to other building material, we suggest and construction adhesive like PL Premium or No-more-Nails that can easily be found at big box stores.
Tips for assembling PVC in Cold Temperatures
The colder it is, the longer the setting time becomes. Where other products simply do not work at cold temperatures, HH-66 works very well in cold temperatures, in fact it has been used on the Alaska Pipeline.
Tip: Store adhesive and the PVC in a warm place before starting work and allow for a longer setting time before removing any tape or temporary supports.
HH-66 will freeze in very cold weather. Due to the concentration of solvents, it usually freezes to a consistency of slush. This will not affect the performance of the cement. If it does freeze, simply store at room temperature until it regains its original viscosity which is similar to maple syrup.
HH-66 can be used in very cold temperatures (- 34 degrees C or -1), however it will take longer for the solvents to evaporate. The surface should feel tacky. Be aware that although the effectiveness of the cement will be good, it will start to freeze depending on the severity of the cold and the length of exposure to the cold.
