What Are The Ways To Improve The Poor Compatibility between Glass Glue And Substrate

The compatibility between glass adhesive and substrate has always been a key topic of discussion in decoration, construction, and other related fields. This compatibility not only affects the quality and effectiveness of construction, but also directly impacts the safety and durability of buildings.

A glass adhesive with good compatibility can ensure a strong bond with the substrate, providing excellent sealing and stability. On the contrary, if the compatibility is poor, it may lead to problems such as weak adhesion, detachment, cracking, etc., seriously affecting the effectiveness of use.

Today, the editor will summarize with you the ways to improve the poor compatibility between glass glue and substrate.

01 Choose the right type of glass glue

✅ According to the material selection of the substrate, different substrates such as metal, plastic, wood, glass, etc. have different requirements for glass adhesive. Choosing a type of glass adhesive with good compatibility with the substrate is the key to improving the bonding strength.

✅ Consider the usage environment: The usage environment of glass glue, such as temperature, humidity, chemical corrosion, etc., can also affect its compatibility with the substrate. Therefore, when choosing glass adhesive, factors such as weather resistance and corrosion resistance need to be considered.

02 Substrate surface pretreatment

✅ Cleaning: Ensure that the surface of the substrate is clean and free of impurities such as grease and dust. Solvent cleaning, mechanical polishing, and other methods can be used for cleaning.

✅ Roughening treatment: Increasing the roughness of the substrate surface is beneficial for the infiltration and curing of glass glue. Rough treatment can be carried out using methods such as sandpaper polishing and sandblasting.

✅ Chemical treatment: Using specific chemical reagents to treat the surface of the substrate, such as acid washing, alkali washing, etc., to improve its chemical properties and enhance its compatibility with glass glue.

03 Optimize construction conditions

✅ Construction temperature: Maintaining an appropriate construction temperature is beneficial for the curing of glass adhesive and bonding with the substrate. Excessive or insufficient temperature may affect the performance of glass adhesive.

✅ Construction humidity: Avoid construction in high humidity environments, as excessive humidity may affect the curing speed and bonding strength of the glass adhesive.

✅ Construction tools and techniques: Use appropriate construction tools and techniques, such as scrapers, nozzles, etc., to ensure that the glass adhesive is evenly and fully applied to the surface of the substrate.

04 Environmental considerations

✅ Avoid direct UV radiation: Prolonged exposure to UV radiation may cause aging and discoloration of the glass adhesive, reducing its bonding strength. Therefore, during construction, it is necessary to avoid direct ultraviolet radiation.

✅ Preventing chemical corrosion: Avoid contact between glass adhesive and corrosive substances such as acids, alkalis, etc. These substances may damage the chemical structure of glass glue and reduce its performance.

05 Choose Heating Curing Method

✅ Heating curing: For certain types of glass adhesives, such as epoxy resin glass adhesives, their bonding strength can be improved by heating curing. Heating can accelerate the curing process of glass glue, making it better adhere to the substrate.

When it comes to the compatibility between glass glue and substrate, the compatibility between stainless steel and substrate is indeed a matter that needs attention! Stainless steel contains a certain amount of alloying elements, which may react with the chemical composition of certain substrates, resulting in poor compatibility.
