epoxy Novolac

news and articles

Epoxy resins have different advantages such as good thermal and dimensional stability, very good resistance to corrosion and chemicals, and excellent electrical and mechanical properties. Their wide application in space and electronic industries is surface coating, structure of adhesives, printed circuit boards, insulating materials for electronic systems and advanced composite materials. In high-tech applications, epoxy resins with low thermal expansion, greater hardness and strength, and better thermal and moisture resistance are required to cover the crystal deformation of epoxy resins in the main and secondary chain groups and improve their physical and thermal properties.

Phenolic resin, also known as phenolic resin, phenol formaldehyde resin and Phenoplast resin, is one of the oldest and most widely used thermosetting resins. These types of resins are prepared from the reaction of phenol or its derivatives with formaldehyde in the presence of a suitable catalyst. Resole and Novolac are two important types of these resins. One of the useful features of these resins is high heat resistance and low price. These resins are used in the production of composites, electronic industries and also as thermal shields.

One of the types of durable and high quality industrial flooring is polyurethane flooring. Due to its inherent properties, Novolac flooring can be used in open spaces and can perform well in halls, factories, parking lots, areas, hospitals, etc. Novolac epoxy precursors have more functionality (average number of active groups per molecule). Also, this formulation provides a higher density of crosslinks, which creates good chemical resistance and thermal properties. This resistance includes resistance to concentrated leachates, sulfuric acid (98%), sodium hydroxide (50%) and pesticides.

Novolac 100% Solid Epoxy Flooring Systems are suitable for use where serious resistance to strong chemicals and solvents is required. EPN systems are used in special solvent tanks, pump beds, pits and other surfaces that are exposed to a lot of light, under Novolac epoxy, it is not based on Bisphenol A epoxy, and it has good resistance to sunlight, which makes EPN resin like Epoxy resin based on Bisphenol A does not degrade and plaster. Electrical and sanitary industries as well as waste and chemical treatment plants, power generation plants and textile machinery are all examples of places where Novolac epoxy flooring is used a lot.

Advantages of Novolac Epoxy:

Novolac epoxy resins are resins that have a chain similar to phenolics in their structure, but contain an organic epoxy functional group. Therefore, in addition to having excellent thermal properties, phenolics are processed like epoxies and with the same curing agents.

1. Having a phenolic resin structure with an epoxies processing system
2. Poly- functionality and, as a result, higher density of transverse connections
3. Better thermal chemical property
4. Better preservation of mechanical properties at higher temperatures
5. Minimizing resin shrinkage
6. Having a higher viscosity than ordinary epoxy resin

Applications of industrial flooring using Novolac epoxy flooring

Fosroc ANZ high performance industrial floor coatings, including Novolac epoxy solution, to protect sub-layers from the aggressive effects of spilled chemicals, which can attack or lower the pH of concrete. It is potentially exposed to reinforcements within the concrete, resulting in structural and ultimate weakness.
