Polyester Adhesives, such as Tenax Transparent Flowing, create what’s known as a ‘chemical bond’ when cured. These typically offer about 40% strength when cured.

Advantages:

• Mostly for indoor use
• Great for filling voids
• Used for laminating edges
• They color well with tints
• Offered in transparent, colored, and clear
• Fast cure time
• Lower price
• When cured, they are brittle (like plastics)
• Do not expand/contract with temperature change

Bi-Component Adhesives, such as PolyTenax, Crystal or Glaxs are the in-between products. Typically offer a bond of about 60%-70% in strength when cured. These products should be chosen for specific applications, as some can be used indoors only and some can be used indoors and outdoors.

Advantages:

• Stronger bond than traditional polyester adhesives
• Used in indoor and some products are for indoor/outdoor applications
• Color well with tints
• When cured, they offer some flexibility and are not as brittle
