Caustic Soda - Sodium Hydroxide (NaOH) Sodium hydroxide (NaOH) is a highly caustic and corrosive compound that is commonly known as caustic soda or lye . The name “ caustic soda ” comes from its ability to corrode or burn organic materials upon contact due to its strong alkaline properties. NaOH is a type of sodium hydrate, meaning that it contains water molecules within its crystal structure. What is caustic soda? In its pure form, caustic soda appears as a waxy, white solid that readily absorbs moisture from the air and dissolves in water to form an aqueous solution. Overall, sodium hydroxide has a wide range of industrial applications, including in the production of paper, textiles, soaps, and detergents. It is also used in the manufacturing of various chemicals, such as plastics and pharmaceuticals. However, due to its highly corrosive nature, sodium hydroxide must be handled with care and caution to prevent injury or damage. What are the applications of sodium hydroxide? Sod...

  Epoxy adhesives Epoxy adhesive is considered one of the most significant adhesives in history, since the beginning of adhesive use. Epoxy adhesives are composed of epoxy resin , which exhibits various properties and characteristics depending on the resin grade and fillers added, such as metals and ceramics. These adhesives have been utilized in the industry for over half a century, offering excellent chemical and physical properties. Typically, they are produced in two components: resin and hardener . What is a epoxy adhesive and its applications? Epoxy adhesives are known for their strong bonding capabilities and resistance to chemicals, heat, and water. They are used in a wide range of applications, including construction, automotive, aerospace, marine, and electronics industries. Epoxy adhesives can be used to bond various materials like metals, plastics, wood, and ceramics. One of the primary advantages of epoxy adhesives is their ability to form a strong bond even und...

  Types of bitumen & applications - Buying bitumen Bitumen is a dark brown or black, non-crystalline and highly viscous substance with adhesive and waterproof properties. It is soluble in organic solutions such as toluene and carbon disulfide. This substance is mainly composed of hydrocarbons , which typically contain around 80% carbon and 15% hydrogen. It is a complex mixture of hydrocarbons and other compounds that gives it unique physical and chemical properties. What are the features? It is a highly strong and resilient adhesive substance, capable of binding an extensive range of materials, even when their properties do not match. The durability of this adhesive is critical for significant engineering projects, including the construction of roads and waterways that require a lifespan of 20 years or more. It is insoluble in water and can act as an effective waterproofing insulator. It also resists most acids, alkalis and salts and does not contaminate water, so it can be u...

  Epoxy Resin Epoxy resin is an adaptable and useful material that has a wide range of applications in various industries. It is a type of synthetic polymer that is created by mixing two different components together, an epoxy resin and a hardener . The nature of epoxy resin and its various types There are several types of epoxy resins with unique features and applications, including: Bisphenol An Epoxy Resin (DGEBA) : The most commonly used type of epoxy resin is Bisphenol epoxy resins, which are produced by reacting bisphenol A with epichlorohydrin. These resins have high mechanical strength, good adhesion, and excellent chemical resistance, making them ideal for a wide range of applications such as coatings, adhesives, composites, and electronics. Novolac Epoxy Resin : Novolac epoxy resins are synthesized through the reaction between epichlorohydrin and phenolic novolac resins. These resins exhibit exceptional thermal stability and high cross-link density, making them ideal ...
