An Introduction to Resin Adhesive and Glass Repair

You may have heard about one of the most effective glass repair techniques to hit the market just over a decade ago – and this method is via liquid resin. The natural resource is readily found on many trees and it can be tapped into and harvested in much the same way as tree sap. In its raw form it can be a little tricky to manage, but once modified and subjected to a variety of processes, the liquid results can be some of the most beneficial to those within the glass treatment industry.

Glaziers in particular have found a use for this type of resource and since its introduction, it has been used to fill gaps in glass, repair cracks and even restore the integrity of car windows, home windows and even door panels that make use of glass. There are plenty of advantages that this unique adhesive offers, such as:

  • The ability to dry transparently, making it ideal for use alongside glass and other see-through materials (including plastic)
  • The tendency for it to solidify into a near-unbreakable mass, which can help to reinforce the strength of glass
  • The renewable nature in which is can be obtained, making it quite affordable to get hold of; helping glaziers to keep their fees as low as possible

Natural resin seeps out of trees and plants, and acts as a bonding agent to stop any bacteria from being able to make its way into cuts and grazes in and around bark. As it is being emitted, it’s very sticky – resembling syrup in both look and feel. Over the course of a few days the resin will dry out, changing in colour as it absorbs shades from the surrounding bark, until an orange or reddish colour is present throughout.

Once solidified, this type of tree resin can never be melted – in fact heat treatment will result in burning and eventual crumbling. This is why glaziers rely on a modified version of this natural component; one that won’t absorb colours, or take several days to dry. By using injection devices and suction cups, it’s now possible to ensure that the resin fills every hole and gap within glass, where it will dry in the space of a couple of hours and then provide an incredibly strong layer of support to the surrounding glass atoms.

As it dries transparently it is suitable for all shades of glass, including stained glass. There are other types of adhesive that may be better suited to piecing broken shards back together, but when it comes to filling cracks, gaps and chips – resin is certainly at the forefront of the reparation process. As soon as the formula hardens, it will be more than capable of lasting for decades with minimal maintenance.

Its durable nature is what makes it so ideal for dealing with damaged glass, as not only can it be used to fill gaps at any angle; its composition makes it strong enough to bond even the most noticeable of cracks, whilst complementing the aesthetic properties.
