The urea formaldehyde resin suppliers in India concentrate on distributing them to aid these industries for a multitude of applications like the production of wood panels, particleboard, airplane, and automobile parts. The core uses of Urea Formaldehyde Resin and properties like water solubility, hardness, abrasion, ease of use with various curing conditions, low cost, etc. lead to its importance for various industrial applications. The chemical has soon gained traction in manufacturing and various other industries.

This blog discusses in detail the properties, characteristics, and uses of urea-formaldehyde resin in industrial processes.

What is Formaldehyde?

Formaldehyde is a highly volatile and significant chemical building block, produced on an industrial scale. It is an active agent you can utilize in controlled industrial operations for various applications. Also, industries combine Formaldehyde solution with other substances to give birth to adhesives and formaldehyde-based resins.

You can also use them as an intermediate to make other chemicals, which play a vital role in the creation of plastics and coatings like polyurethanes.

Since formaldehyde has amazing antibacterial properties, a small fraction of it is present in healthcare applications, which include vaccines, disinfectants, etc.

Urea Formaldehyde Resin-An Overview

The Urea and Formaldehyde fuse to form a polymer or non-transparent thermosetting resin called Urea-formaldehyde or urea-methanal. Urea Formaldehyde or UF resin is an integral component in the production of various products. UF resins exhibit high-end performance, with amazing abrasion resistance and heat resistance.

Various Urea Formaldehyde Resin Suppliers in India distribute UF resins in surplus quantities since they are the major addons to the production of adhesives, molded objects, and Medium Density Fibreboards. Hölzer synthesized them first in 1884, with his co-worker Hanns John, where they got the first patent for the resin.

Let’s now dig further deep into the properties and uses of Urea Formaldehyde resin to let you decide whether this is the ideal polymer for your industrial use.

Core Properties of UF Resin

What properties make Urea Formaldehyde most useful? Here are the properties that distinguish Urea Formaldehyde resin from the other polymers and make it ideal for various industrial uses.

Great Tensile Strength

It means the extent of stress the material can resist while being pulled or stretched before it can break.

Higher flexural modulus

It is the ratio between stress and strain that a material can bear while bending before the substance yields.

Huge heat distortion temperature

This is the temperature level at which the core material begins to “soften” after you expose them to the fixed load under increased temperatures.

Reduced Water Absorption

The substance exhibits a minor level of water absorption. Additionally, Polyvinyl acetate helps to modify the UF resins to enhance the water resistance properties too.

Higher Mold shrinkage

It indicates the volume of shrinkage of the molten plastic inside the cavity of a mold that takes place during the procedure of solidification and cooling.

Great surface hardness 

Urea-formaldehyde resin offers high surface hardness. You can use the bonding properties of the resin for adhesives and other interior applications.

Elongation at break

It is the ratio between the initial length and the changed length once the material breaks.

Volume resistance

It offers high volume resistance, which is the electrical resistance that a body offers to the current that passes through the substance. It also can contribute to high-efficiency self-repairing anticorrosion coatings that can strengthen the products.

Refractive Index

UF resins include a refractive index that calculates to 1.55.

General Uses of Urea Formaldehyde Resin

Various industries get UF resins from top chemical distributors in India for various uses of Urea Formaldehyde resins like textiles, paper, cotton blends, anti-wrinkle fabrics, etc. You can also find them in the coating material for electrical equipment like desk lamps. The elemental analysis states that the chemical combination of Urea and Formaldehyde is not toxic. Various examples of applications of amino resins are automobile tires to enhance the bonding of rubber to the cord, paper to improve tear strength, electrical device molding, jar caps molding, etc.

Major Industrial applications of UF Resin

Ever heard about Amino resins? They are the amine condensation products like Urea Formaldehyde or Melamine Formaldehyde used widely in the surface coatings industry. To be more precise,  when the chemical composition of the reaction of Formaldehyde, ie. (HCHO) and amino (-NH2) compounds occur,  they further undergo a reaction with alcohol (R-OH). This is how you can obtain the amino resins.

Urea-formaldehyde polymers textile fibers undergo remarkable analysis, due to their shrink and wrinkle resistance. You can combine them with alkyd paints to elevate the surface hardness of the healing coatings used. Top Chemical Distributors In India supply UF resins to various industries in large quantities due to their long shelf life and amazing applications as listed below.

Alkyd Amino Systems for industries

Alkyd resins are complex polyesters and shape when the co-polymerization of polyols, fatty acids, and phthalic anhydride occurs. The blend of Amino resins and Alkyd can help to form a specific coating called stoving or baking enamel. When stoving and baking happen at a specific temperature on formation and time.

You can use the combination of Alkyd or the content of melamine resin to prepare the conversion coating known as ‘baking enamel’. Cure this mixture at 80 °C to 200 °C temperatures for 20 to 30 minutes. Many industries thrive with an ideal chemical supplier in India and use the alkyd amino systems for two major functions as shown below.

Alkyd Amino Systems for Stoving paint

When you modify the Epoxy-Amino thermosetting at high temperatures, it produces Stoving paint, which is a form of non-yellowing fatty acid. This technique is significant in industrial applications such as water filters, refrigerators, washing machines, decorative finishes, drum linings, kitchen appliances, and metal coating. interior and exterior coating, etc.

Stoving paint offers wonderful gloss, amazing finish, and color retention features to the substrate. The design of the product can satisfy the complicated test specifications of the automotive industry like gasoline resistance, color retention, and scratch resistance.

Key Features of Stoving paint include outstanding corrosion resistance, high resistance to chemicals, alcohol, and solvents, non-reactive to grease, vegetable oil, etc, and high weather resistance. It offers great fixing on Aluminium and Steel and provides good suppleness. It can withstand over 100-120 degrees Centigrade temperature. The amino-alkyd resins offer competent mechanical properties and abrasion resistance to the products with good UV stability, physicochemical stability, and oxidative stability.

Uses of stoving paint

High-quality resins, durable pigments, and chosen additives combined with stoving enamel impart great color retention, and a sturdy and smooth finish to the products. The core applications of stoving paint include:

• Home appliances
• Steel furniture
• Electrical fixtures
• Steel Furniture
• Commercial appliances
• Decorative Coating for exterior use
• Organic coating
• Medical equipment
• Automobile Industry

Alkyd amino systems for Industrial Baked Paint

Baked paint is a product with paint products that offer high durability. It consists of a paint film coating that can safeguard the metal structures from environmental issues like temperature, impact, etc. It is very different in types and colors. 

They dry the paints with heated air which is further re-circulated inside the Oven. Here, you heat air, the fans circulate them and the entire process makes use of a heating chamber.

Industrial baked paint offers great resistance to bending and has a high solvent resistance. They also offer good chemical resistance and retain the glossy finish of the substrate.
