Adhesives General Information

 

Some type of adhesive or grip will be required to hold your gasket in place.

 

Many different adhesives are available because there are a multitude of surfaces to which gaskets must be applied. It is important to select the right adhesive for the job and your Clean Seal® specialist can help

suggest the correct adhesive method for your specific application.

 

It is critical that you communicate all conditions that may apply to your specific needs. Clean Seal® staff members can only make suggestions based on the information they receive from you.

 

No matter what bonding surface you apply the gasket to, it must be clean and free of any surface contaminants such as oils, greases, plasticizers, solvents, mold releases and dirt in general. Most bonding failures are due not to the adhesive failing, but instead to the failure to properly clean the surfaces.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

3M™ Heat Bonded Tape System

Heat isn’t required to attach the gasket to the substrate surface. Instead, Clean Seal® uses high tech heat-laminating equipment to thermally bond the tape to our extruded seal or gasket parts. This thermo process ensures a strong reliable bond of the tape to the gasket.

 

You simply peel off the liner and press the part into place. The part is easy to align and stays in place during application. You can securely attach gaskets to just about any surface without the expense or work of mechanical fasteners or messy contact adhesives. That’s the real benefit of 3M™ HATS.

 

NEW in 2002

A new 3M™ HATS with an even more aggressive bonding ability is being offered by Clean Seal®. The 3M™ Acrylic Plus Sealing Tape is especially designed for automotive and transportation applications allowing for superior adhesion to automotive paint surfaces.

Rubber-based pressure-sensitive adhesives

Rubber based adhesives are non-polar by nature and contain as many additives as our rubber compounds. They adhere well to non-polar substrates such as polyolefins, EPDM’s, and silicones. They do not bond well to polar substrates such as polyacrylates, polycarbonates, etc.

 

Rubber based adhesives have a high initial bond to the substrate.

 

Acrylic-based pressure-sensitive adhesives

Acrylic adhesives are polar in nature and tend to adhere well to polar substrates such as metals, glass, polyesters, polycarbonates and neoprenes. Because acrylics are thermoplastics by nature, they soften when exposed to heat and harden when cooled.

 

Acrylic adhesives are inherently soft at ambient temperatures permitting it to flow under light pressure allowing for intimate contact with the substrates. This ability to flow is important when bonding to irregular or rough surfaces.

For permanent applications, the 3M™ Heat Activated Tape System (HATS) is generally used. The acrylic and rubberbased PSA adhesives are normally used to hold the gasket in place before the gasket is more permanently attached by mechanical fasteners. Acrylic adhesives work best on painted or fiberglass surfaces while the rubber-based adhesives work better on aluminum, bare metal and stainless steel.
