Resins are typically a sticky organic substance, insoluble in water, exuded by some trees and other plants. They are also synthesized chemically. Such Synthetic Resins are either a solid or liquid synthetic organic polymers.
They are generally used as the basis of producing plastics, adhesives, varnishes, or other products.
NEO specializes in manufacture of almost all types of ALKYD / PHENOLIC/ MALEIC / CNSL / AMINO resins.
Expertise in formulating Modified Resins to give enhancement of key
Neo’s Resin products are well know under brand name of NEOREZ.
No NEO also gives hard resins.
No NEO also gives hard resins.
As you know, all electrical machines run when electric current pass through its coil or winding. The electric current has two components; one component gives active power, which is being use for generating useful energy and other component gives reactive power, which generate heat in electric machines. The other component also called loss current. The electric machines run in very adverse environment of humidity, chemical vapor, temperature and vibration. As result of this adverse environment, three different kind of stress (Thermal, mechanical and chemical) work at a time on machine, which cause failure of machines. Insulating varnishes is specially formulated to protect the electrical machine from these stresses, so that life and safety of electrical machine is enhanced.
The solution of resin and solvent without pigment are called varnish.
Insulating varnishes are classified on the basis of drying nature and their thermal class. According to drying nature varnish is classified as air drying and baking type. According to thermal classes the varnishes are classified as A, B, C, E, F and H.
NEOVAR is used for applications in transformer, chokes, coils, all kinds of motor, fans, circuit board, insulation tapes, glass laminates, AC/ DC motor, generator, alternator, armature etc.
It is applied by dipping, pouring, brushing and vacuum
The small component like small transformer, chokes etc can be applied by dipping the component in varnish tank and hang for drying. The bigger component like motor, rotor, alternator etc can be applied by brushing/pouring. Some precision electrical machine or coils, which runs on very high voltage like ignition coil, fly back transformer, are applied by vacuum impregnation.

|NEOVAR Red / Grey
|All kinds of motors, alternators, generators, fans, and transformers and chokes as finishing varnish.
The thinners are added to varnish to improve penetration property of varnish, so that Neovar reach to every turn of coil. The quantity of thinner added as per permissible limit given in technical data sheet. Normally, with 1 part of varnish 1part of thinner added but the thinner quantity can be increased or decreased depending upon method of application.
The insulating varnishes are chosen as per following method
a) First identify the thermal class of electrical machine on which varnish to be applied from customer.
b) Choose a varnish whose thermal class is matching to that of electrical machine but not less than of machine class.
c) If you have baking facility then choose baking type varnish or else stick to air drying varnish
What do you mean by Flexibility of varnish
It is defined as property of varnish film and it’s determined by resistance to crack when copper wire specimen coated with varnish has been bent for 180 degree around the mandrel.
What is Volume resistivity
This is defined as resistance of material to leakage of electric current through its body. It is measured as Ohm –cm.
What is Dissipation factor
It is a measure of electrical losses and significantly it should be minimum as possible for efficient performance of insulating material.
What is Dielectric constant
It is ability of insulator to store the energy and hence high dielectric constant is desired
What is Flash point
It is property of material and defined as the minimum temperature at which material would catch fire when vapor pressure of and atmospheric pressure attains equilibrium.
What does Dilution Ability & Compatibility
It denotes the percentages in volume of thinner that can be added before the first turbidity appear.
The maximum electrical voltage at which insulating material fails for insulation is called BDV. It is measured in terms of KV/mm.
The thermal class or temperature index is related to temperature resistance of insulating varnish. The thermal class is denoted by A, E, B, F, H and C. These letters correspond to particular temperature resistance A=1050C, E=1200C , B=1300C , F=1550C, H=1800C, C=2000C
The properties of material or substance, which retards the flow of current through it when voltage is applied across its terminal, are called electrical resistance. The electrical resistance measured in Ohm- cm.
These are used for all building and structures in order to eliminate possible defects in surfaces or structures prepared as well as to enhance properties of such surfaces or structures.
Waterproofing Products / Insulation Coatings / Bonding Agents, Admixtures & plasticizers / Grouts / Curing Compound / Concrete Sealers / Crack filling compound / De Shuttering oil / Industrial Flooring / Micro Concrete / Floor hardener etc.
Neo specializes in waterproof coating & insulation coating based on liquid membrane technology.
These are seamless homogeneous ready to use superficial coating that are cold applied. They are elastomeric coating with great flexibility to withstand structural expansion contraction. These products do not crack and themselves serve as a crack bridging coating upto a limited hair line cracks. These products upon coating do not add load on to the surfaces unlike other cement based coating products.
The brand name is NEOPROOF.
The brand name is NEOCRETE.
Bonding agents are specialised polymers that enhance the bonding ability of one concrete surface to another.
They are of different types based on their polymer composition viz – Acrylic / SBR / PVA / Epoxy.
They are almost similar in all its features , benefits and applications. SBR bonding agent is preferred for Internal applications due to its poor UV resistance while Acrylic bonding agent is ideal for both external & internal applications. SBR has slightly more bond strength & flexibility compared to Acrylic.
All cement based structures tend to crack and also tend to give way to leakage / seepage due to irregularities in the formed structures. The same may be due to several reasons. Honeycombs , Capillaries present in concrete / cement surfaces give rise to leakage. To eliminate these defect IWA is added in the dosage of 200 ml per 50 kg bag of cement to take care of possible defects. These products also improves crack resistance of structure.
Heating, Ventilation & Airconditioning use Ducts for air circulation. To prevent transmission of heat from outside , the ducts are insulated with suitable insulating materials. Duct coating materials are used to bond the Insulating materials like PU foam / Fibre Glass Wool along with the duct. They are also coated over the insulting liner material to protect them from external moisture & maintain hygiene.

Even minor rust adhering to surface will spoil the paint in long run as rust will propagate through the paint. Hence it is always advisable to make proper surface preparation before painting / coating an substrate / surface. Loose rust particles are removed wire brush / sand paper and then rust adhering / clinging to surface are removed by use of Neo’s Advance Rust Treatment products. After Rust Removal area is wiped clean. Then carry on with primer & paint application.
NEO offers a revolutionary product RUST O KILL employing 3 in 1 Technology that not only removes RUST but also converts it. It also acts as a perfect degreasing and cleaning liquid. Very hand product for RUST treatment before painting.
Epoxy paints are highly durable paints that can be used for all types of adverse environments. They are highly anticorrosive and give a very aesthetic appeal to substrates.
Yes PU paints are equally high standard as compared to Epoxy paints. In some ways it is better as they offer additional qualities like better sheen, fast curing, flexible UV resistance coating.
Of course Primer can be used for prevention of parts from Rust. Paint can be applied during the time of delivery / dispatch to customer.
Neo’s NIS 40 Liquid Rust Preventive OIL can be used for preventing parts from rusting and corrosion for a prolonged period of 45 days. The oil can be brush applied / sprayed or dipped and left exposed. For 45 days the product will not catch rust. Re application will be required post 45 days. Ensure that the parts are properly degreased before paint application to remove last traces of oil film if any left over.
NEO has inhouse Salt Spray Testing system for checking Corrosion resistance of any coating. Neo ensures that its coating passes its very stringent salt spray test.
