Glaziers often rely on one particular substance for help when it comes to their glass repair services – and this formula is referred to as resin adhesive. It’s commonly made from the sap that exudes from trees, although man-made alternatives are readily available (and can sometimes be more affordable).
These types of adhesives are stored at particular temperatures and during their manufacture, they are introduced to composite materials that can affect the way in which the formula dries once it comes into contact with oxygen in the air. Most resins will then be injected into chips, cracks and even split glass to help repair the glass before being allowed to dry and solidify.
What happens once dried?
When the formula is able to dry, the chemical compounds within the resin will typically form a bond to the glass atoms that they come into contact with. This bond can be far stronger than that of the glass itself, allowing window repairs to take place in a way that can restore functionality of the panel in question, with minimal fuss.
How long does the resin take to dry?
This will usually depend on the manufacturer and any environmental factors that may be present. A good guideline for resin adhesive is 4 hours – although this process can be both sped up and slowed down depending on the needs of the glazier. For example, if someone is facing an emergency such as the risk that their glass window may shatter at any moment, then a high yield and fast drying adhesive might be used.
If the window has suffered with minor warping however and cracks are beginning to form, then the adhesive can be injected simultaneously with any reshaping services (often utilising heating tools).This can allow the pane to return to its regular shape (if possible), whilst the adhesive gradually solidifies to hold the reshaping in place.
Is the adhesive permanent?
When properly injected, the formula can last for decades without any sign of wear and tear. Many people find themselves concerned over its presence however – especially as in the past, these types of resins used to possess colours ranging from oranges and reds through to yellows and whites. These days however, the formula dries hard and transparent – and once solidified, a high grit sand paper (or window treatment tool) can be utilised to reduce the appearance of the dried composite.
If an issue with a window has been spotted, then the earlier the treatment takes place, the more likely it will be that the owners won’t have to fork out larger sums for a complete glass window replacement.
