Coal Tar Epoxy- Meaning, Lending Properties & Application

When it comes to safeguarding surfaces subjected to exceptionally corrosive environments, coal tar epoxy coatings find application. This coating is a powerful blend of refined coal tar and epoxy resins. The resultant high solid coatings and paints made from coal tar epoxies are used to provide prevention against moisture and microorganisms in underground systems. These systems include tanks, pipelines, water treatment facilities, sewage areas, etc.  When a surface is treated with coal tar epoxies, it gets a number of properties, as discussed in the following section.  Properties Provided By Coal Tar Based Epoxies It helps in developing paints and coatings that can be easily applied using a brush, spray, or roller. Since it bonds greatly with oily surfaces, it is chosen to coat garages.  The paints and coatings produced by these epoxies are resistant to corrosion, abrasion, impact, chemical, and thermal shock.  Protection against soil stress is also provided. Provides a mat

How Bitumen Waterproofing Membranes Are Applied On Roofs

Waterproofing is inevitable when it comes to safeguarding buildings from the ill effects of water. When done for a reinforced concrete roof, waterproofing membranes come in the form of sealed rolls on the construction site. This membrane is then opened, unfolded, and spread firmly on the surface using tar-based adhesives and blowtorches. The APP waterproofing membrane is one such torch-on plastomeric waterproofing membrane manufactured from bitumen. This membrane is best known for its durability and superior tensile strength and therefore is used for several constructions.  Let us read in the following section, how these waterproofing membranes are applied on roofs. Procedure for Applying Waterproofing Membrane On Roofs Preparing the Surface At first, the surface is cleaned from dirt and checked for dryness. The membrane is not installed in temperatures below 45 degrees Fahrenheit. Also, for slopes up to 3 inches, membranes are laid perpendicular to the slab. While fo

What Are Polysulphide Sealants?

Polysulphides are chemical compounds made from chains of sulfur atoms. This refers to a class of polymers, composed of several sulfur atoms and hydrocarbons.  A polysulphide sealant or adhesive is a resin that provides flexible and chemical-resistant sealing properties. These polysulphide resins are used as construction sealants and have excellent resistance to fuels, saltwater, ozone, and even sunlight. They react completely and perform best in slightly elevated temperatures. They come with a peculiar smell, which is not harmful to the human body.  Polysulphide adhesives are an ideal choice when it comes to sealing joints. Thanks to their qualities like amazing flexibility and adhesion that are inevitable to seal joints. Let us know in the following section about the properties and application of these adhesives.  What Are The Properties Of Polysulphide Adhesives Polysulphide adhesives: Are capable of underwater curing Resistant to chemicals Resistant to shock, i

What Is Bitumen & How It Contributes To Road Construction

Bitumen is a material that takes birth through the distillation of crude oil, therefore called a by-product of crude oil. The distillation process first removes the lighter crude oil components such as diesel, gasoline, and high octane fuels. When these primary products are refined out, the process leaves behind the heavier component, called tar. This tar mixture comprises hydrocarbons and a high concentration of bitumen. This bitumen is further refined to make an app waterproofing membrane , sealants, etc. Bitumen is popular for its waterproofing and adhesive characteristics, therefore find application in the construction of roads and highways. Let us read in the following section what else makes bitumen ideal for road construction. Why Bitumen Is Used In Road Construction? Chemical Composition As mentioned above, bitumen is composed of hydrocarbons and a high concentration of organic materials. These components are adhesive in nature and capable of establishing robust
