What is the Epoxy?

Post

Epoxy normally applied to commercial and industrial flooring. Epoxy coatings are usually applied over concrete floors to create a high-performance, smooth, and long-lasting surface to last several years and tolerate heavy loads. Many industrial buildings, warehouses, and commercial places rest on epoxy floors to keep clean and safe conditions for people, facilities, and inventory Horizon … Continued

Properties

Post

Epoxy resins, sometimes called polyiodides, are a group of reactive prepolymers and polymers which contain at least one epoxide group. The resins can be reacted (cross linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants having polypractical amines, acids and acid anhydrides, phenols, alcohols and thiols. The co-reactant is often … Continued

Epoxy Resins

Post

Epoxies shows some differences from polyester resins in that they are cured by a ‘hardener’ rather than a catalyst. The hardener, often an amine, is applied to cure the epoxy by an ‘addition reaction’ where both materials take place in the chemical reaction. The chemistry of this reaction means that there are usually two epoxy … Continued

What kind of material is Epoxy Resins?

Post

Usually identifiable by their characteristic amber or brown coloring, epoxy resins have a number of useful properties. Both the liquid resin and the curing agents form low viscosity easily processed systems. Epoxy resins are easily and quickly cured at any temperature from 5°C to 150°C, depending on the choice of curing agent. One of the … Continued

Recycling and Bio-Based Epoxy Systems

Post

As mentioned above, Epoxy thermosetting composites are high-performance elements with significant industrial uses. However, recycling of thermosets and their filling matters are challenging. However, significant research and development possess been done to enable recycling of thermosets, thus allowing the plastics to be broken down and reformed. There are some new developments in epoxy thermosets which … Continued

Epoxy Resins versus Polyester Resins

Post

  Epoxy Polyester Extremely powerful and great flexural Strength The hardener and the temperature determine epoxy resin cure time Resistant to wear, cracking, peeling, corrosion and harm from chemical and environmental degradation Possess a bonding strength of up to 2,000 psi Epoxy is moisture resistant after curing Brittle and prone to micro-cracking Generally, costs slightly … Continued

Flame Retardants

Post

They are added to epoxy resins to incorporate FR characteristics. The presence of halogens and char-forming aromatics in the epoxy-curative based resin decreases flammability. Colors and Dyes A wide variety of colorants can be used with epoxies such as inorganic pigments except chrome greens, natural siennas, zinc sulfide white etc. and organic pigments such as … Continued

How are Thermoplastic Additives used?

Post

They are applied to increase the fracture toughness of epoxy resins. Only relatively low MW TPs can be dissolved in epoxy resins. Commonly used thermoplastics are phenoxy, polyether block amides, PVB, polysulfone, polyethersulfone, polyimide, polyetherimide, nylon. As compared to rubbers, thermoplastics are more effective tougheneres in highly cross-linked matrices and they do not tend to … Continued
