Bostik is a manufacturer and distributor of adhesives and sealants for the construction, industrial and consumer markets. With annual sales of €2.7 billion, the company employs 7,000 people and has a presence in more than 45 countries. Bostik is part of the French-based Arkema group.
Natural sealants and adhesive-sealants included plant resins such as pine pitch and birch pitch, bitumen, wax, tar, natural gum, clay (mud) mortar, lime mortar, lead, blood and egg. In the 17th century glazing putty was first used to seal window glass made with linseed oil and chalk, later other drying oils were also used to make oil-based ...
While the inventor of the commercial Bostik product is unknown, [3] a precursor was created around 1970 as an accidental by-product of an attempt to develop a sealant based on chalk powder, rubber and oil. Blu Tack was originally white, but following fears that children could mistake it for chewing gum, a blue colouring was added.
A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
Unlike the other methods, this method maximizes the tensile stress, therefore, results may not be comparable. The test is done by securing loading fixtures (dollies) perpendicular to the surface of a coating with an adhesive. Then the testing apparatus is attached to the loading fixture and aligned to apply tension perpendicular to the test ...
Hot-melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun.
Epoxy adhesives can be developed to suit almost any application. They can be used as adhesives for wood, metal, glass, stone, and some plastics. They can be made flexible or rigid, transparent or opaque/colored, fast setting or slow setting. Epoxy adhesives are better in heat and chemical resistance than other common adhesives.
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
