Glass Adhesives
Permabond glass adhesives are suitable for a variety of applications on decorative and structural glass. They are excellent for bonding glass to glass or glass to metal and form very high strength bonds for load-bearing joints, such as those found in glass furniture and display cases. Flexible and stress absorbing, Permabond glass adhesives are available for use in applications that require substrates with different thermal expansions to be bonded. Their high optical clarity and resistance to yellowing make them very popular for “invisible joints”.
Typical Applications:
- Furniture
- Art glass
- Lampshades
- Bathroom cabinets
- Shelving
- Mirrors
- Doors
- Glassware
- Display cabinets
- Decorative window and door bevels
UV Glass Adhesives Key Features
Permabond UV curable glass bonding products are suitable for a variety of uses, some of the product highlights are listed below:
- Permabond UV610 provides structural strength on steel to glass.
- Permabond UV620 is the product of choice for optical clarity.
- Permabond UV625 is a thixotropic gel, ideal for dispensing on vertical surfaces.
- Permabond UV632 is ideal for bonding acrylic.

Epoxy Glass Glue
One and two-component epoxies bond glass, using Permabond 2K primer aids adhesion and long-term durability. For a non-yellowing bond, UV-curing adhesives are normally a better option.
Structural Acrylic Glass Glue
Structural acrylic glass adhesives such as Permabond TA4246 bond glass to glass as well as to plastic and metal. They are often preferred for bonding hinges and fitting to the heavy, structural glass found in turnstiles or railings. High strength, structural, durable bonds that offer high peel strength, impact resistance and absorb the differential expansion and contraction stresses between dissimilar surfaces help to reduce the chance of glass cracking from thermal shock.
Cyanoacrylate Glass Glue
Due to the basic nature of glass, cyanoacrylate adhesives cure very rapidly on glass and appear to have a strong bond. However, the accelerated cure creates stresses in and around the bond which makes the cured adhesive prone to degrade over time. These stresses, the brittle nature of cyanoacrylate adhesive, and the significant difference in the coefficients of thermal expansion between the glass and the adhesive can contribute to bond failure. To improve results, test a rubber toughened cyanoacrylate such as Permabond 731 but be mindful that the bond will not be permanent. In summary, cyanoacrylate adhesives are not good glass glues.
MS Polymer Glass Glue
Permabond MS359 Clear a single-part, room temperature curing MS polymer glass adhesive. It is ideal for use on a wide variety of substrate materials including metals, glass, and composites. MS359 Clear is perfect for exterior construction applications as it has excellent resistance to weathering, is non-yellowing, and produces a discreet, aesthetically pleasing bond.
