Adhesive
Adhesive is commonly known as “glue”. It is the substance that links two materials together through the adhesive and cohesive strength of the interface. There will be no significant changes to the structure of the bonded object, and it will give sufficient strength to the cemented surface.
Civil engineering construction industry: There are many occasions and varieties of adhesives used in civil engineering construction industry.
For example, vinyl acetate latex is widely used in interior decoration and furniture manufacturing, and SBR latex, epoxy resin, and polyurethane glue are widely used in wallpaper, ceramic tiles, sanitary ware, plastic products, pipes, and pipe fittings.
