What type of adhesive is stone adhesive?
Stone adhesive, also known as stone adhesive, refers to all types of adhesives used in the processing and application of stone (including repair, reinforcement, composite, bonding, and maintenance), which fall under the category of fine chemicals. It is a modified tile adhesive specifically developed for large cultural stones, artificial stones, and stones with high water absorption rates, used for adhering to interior and exterior walls.
Types of stone adhesives
1、Stone composite adhesive: Stone composite adhesives are primarily used for bonding and joining various materials such as marble, granite, ceramic, aluminum honeycomb (aluminum sheets), glass, wood, inorganic boards, and plastic boards, as well as bonding similar and dissimilar materials.
2、Stone Repair Mortar Adhesive: Stone repair mortar is primarily used for repairing cracks, holes, pits, and other imperfections on marble and granite surfaces, as well as for reinforcing and enhancing the appearance and brightness of stone. It is also used to reinforce the back of stone mesh.
3、Stone Bonding Adhesive: This product is used for bonding and repairing natural stone, artificial stone, ceramic, metal, concrete, and glass products. Applications include stone edge bonding, marble or mosaic patterns, irregular stone connections, stone dry hanging, architectural tie rods, building sealing, and bonding abrasive tools.
4、Install adhesive: Stone installation adhesive products are primarily used in the stone installation process for dry hanging, sealing, and bonding.
Advantages of stone adhesives
1、Stone adhesives exhibit excellent bonding strength and durability, resulting in a long service life.
2、Stone adhesive saves time and materials. Stone adhesive utilizes a thin-layer application method, effectively reducing the occurrence of air bubbles during installation, resulting in stronger adhesion and reduced wall weight.
3、The stone adhesive can be applied to substrates with low water absorption.
4、Stone adhesive has a certain anti-leak and anti-permeation function, preventing white deposits and mold growth from appearing in stone joints.
5、Stone adhesives exhibit excellent flexibility, and the adhesive can withstand temperature fluctuations caused by expansion and contraction, providing good elasticity.
6、The stone adhesive has a long setting time, allowing sufficient time to adjust the stone layout angle.
7. When applying stone adhesive, avoid wetting the wall surface, making it easy to use.
Disadvantages of stone adhesives
The adhesion strength of the stone adhesive is poor, with a shrinkage rate of 10%-15%. The internal stress within the adhesive is high, and the adhesion is weak. In humid and wet environments, the main resin will gradually decompose, especially in acidic and alkaline rain environments, which will lead to a decrease in adhesion strength.
