Comparing HH-66 Vinyl Cement & Contact Cement

SKU: X-HT-300365



HH-66 Vinyl Cement is a superior quality, fast-drying, waterproof solvent-synthetic resin adhesive. It’s used extensively for bonding vinyl coated and vinyl laminated fabrics together. With so many uses, we’re proud to offer this reputable product here at Sailrite. This adhesive is sometimes compared to contact cement, but we’re here to explain some key differences between these two products.

As stated previously, HH-66 vinyl cement is a high-strength adhesive used to bond and repair vinyl fabrics. An important factor that allows this product to excel is that HH-66 Vinyl Cement is unaffected by the chemicals found in vinyl products. In fact, it’s resistant to numerous chemicals often encountered in both industrial and manufacturing environments. This means that you won’t have to worry about it potentially failing or losing its strength over time. And it reaches full strength after only one day once brushed onto the desired material.

You can use HH-66 to bond vinyl coated and vinyl laminated fabrics like Shelter-Rite® and Weblon® to themselves or to various materials. It can also be used to securely bond urethanes, vinyl foams and films, leather and metals. Plus it’s an outstanding product for sealing or waterproofing stitched seams!

HH-66 will not work on polyolefin materials. The most common polyolefins are polyethylene and polypropylene. These materials are seen in items like store-bought blue tarps and sheeting.

Contact cement is an adhesive product usually made from polychloroprene (neoprene) or natural rubber. This allows it to successfully bond together products such as laminates, rubbers, plastics, some fabrics and nonporous materials. While you can use contact cement in place of HH-66 Vinyl Cement for repairing vinyl, it is not recommended. Why? Contact cement does not share the resilient properties of HH-66, so vinyl products will eventually break down contact cement and the bond will not last as long as HH-66. The chemicals that leach out of vinyl products — such as on a vinyl tarp or cover — will eventually lead to the contact cement failing and losing its adhesive bond. Lastly, contact cement is not capable of creating as strong of a bond as that made by vinyl cement, regardless of the material used.

When you’re working with vinyl coated and vinyl laminated products, it’s best to stick with the high-performance HH-66, available in a variety of sizes at Sailrite. To help you get a better idea of the astounding capabilities of HH-66, we’ve included a short video of it in use bonding Shelter-Rite fabrics together for a repair.
