Use epoxy curing agent for tough and durable polymers

Why epoxy curing agents are used worldwide? The reason because they are found to emulsify and harden both liquid and solid epoxy resins which eventually delivers tough and durable polymers. You can see numerous applications where these agents bring immense change including concrete polymers/sealers, industrial & decorative concrete floor coatings, wall coatings, high build self-leveling floor coatings, epoxy modified cements, and anti-corrosive primers.

Now you can easily search for the manufactures as a large number of companies are involved into manufacturing these epoxy curing agents and waterborne polyurethane dispersions. The demand for epoxy curing agent arises from businesses involved in coatings, sealants, elastomers, and adhesives. However, it is extremely important to conduct a detailed research before giving purchase order to a particular company. You can refer to internet for your research as this medium is not only cheap but effective as well.

This agent is high in demand due to its outstanding qualities in the fields of adhesion, abrasion, chemical resistance, flexibility, and toughness. An important thing to remember is that poxy curing agents are generally classified by the excellent resistance to abrasion and also high mechanical resistance. This is another reason why the demand for these materials is so high.

Get superior moisture protection with moisture scavengers

When it comes to determine the biggest threats affecting the performance of coatings and sealants, moisture occurs at top with many issues. This is why moisture has an inherent property to react with isocyanate for the production of gaseous carbon dioxide which in turn results into bubbling, pinholing, and many other issues. This moisture impurity can start either from within the formulation or as result of increased atmospheric humidity. It is universally known fact that solvents may contain some traces of water which can sometimes lead to the dispersion of urea crystals.

The good things is that the evolution of moisture scavengers has made things easy and they play a major role in bringing down the moisture contamination drastically. They are quick reactant and hydrolyze on exposure to moisture. It also eliminates CO2 bubbles and pinholes in two-component systems and reduces glossing an hazing under extreme humidity application conditions.

Moisture scavengers are widely used for the removal of water from polyols in two component polyurethanes along with the removal of water from solvents, plasticisers, and pigment pastes. It prevents gassing and gelling in single component systems. Incorez is a global leader in oxazolidine chemistry, manufacturing a diverse range of products marketed under the Incozol® umbrella.

Moisture Scavengers – For an effective protection again moisture

Moisture is known to be the biggest threat for the failure or loss of performance in coatings and sealants. It has an inherent property to react with isocyanate for the production of gaseous carbon dioxide this in turn exhibits bubbling, pinholing and other issues. There are basically two reasons for the onset of moisture. This moisture contamination can induce either from within the formulation or as result of increased atmospheric humidity. It is globally known that solvents may contain some traces of water which can sometimes lead to the dispersion of urea crystals.

However, the introduction of moisture scavengers has made things easy it is meant to bring down the moisture contamination considerably. They are fast reacting and hydrolyze on exposure to moisture. It also eliminates Co2 bubbles and pinholes in two-component systems and minimizes down glossing and hazing under high humidity application conditions.

Moisture scavengers are heavily used for the removal of water from polyols in two component polyurethanes as well as the removal of water from solvents, plasticisers, and pigment pastes. It prevents gassing and gelling in single component systems. Incorez is a global leader in oxazolidine chemistry, manufacturing a diverse range of products marketed under the Incozol® umbrella.

Polyurethane Prepolymers – Meant for excellent solvents resistance

A large number of industries make the use of polyurethane prepolymers because of their amazing chemical resistance along with solvents and graffiti. The only issue with these prepolymers is their high cost. It restricts their usage and used only in certain applications. They are used in the production of sealants, expansion joints, and adhesives. For more diverse use, they are used on the interior walls of hospitals, schools, and other public buildings.

In short, polyurethane prepolymers are used in those applications that require a great resistance against chemicals and solvents. There are certain advantages of using these agents such as they show amazing weather stability and colorfastness. The advent of these prepolymers has brought great advantage to adhesive and sealant formulators. The formulators can now expect optimum efficiency and enhanced performance benefits, and this is the major reason why these products are high in demand all over the world. Nowadays, there are large numbers of companies involved into the manufacturing of these polyurethane prepolymers and waterborne epoxy agents.

Don’t forget to do a detailed research on polyurethane prepolymers that will help you locating the most perfect manufacturer/supplier for your application. The more dedication you will show in your research, the better results you will get in terms of great chemical resistance and long lasting

What makes your paint more stable

After getting my house painted last year, I went into depression. Really... it was that bad. No, I don’t mean the paint was bad but what I want to imply is that the trauma after seeing your newly painted house appear ghastly right after a small thunder shower was depressing. I did not know what to do. I had spent almost a month and half my savings for the year on getting the paint job done but to my misfortune all the efforts went down the drain.

I was constantly intriguied by this question as to why me and what was wrong. I asked the dealer and found out about the paint specifications, all seemed normal on that front. Then I asked an architect friend of mine about any problem with the raw material I used while building my house, after some deliberation and inspection, my friend told me there was no problem in the way my house was built. Then what? I asked but got no answers in return.

One fine day, this same architect friend of mine called me up and asked if it had rained after i got my house painted? I replied in affirmative and reinstated that it was a mild shower nothing like the torrential rains this part of the state sees. And bang I had the answer. Even in the worst of my dreams I could not think that t will be a chemical called oxazolidines that will be responsible for the disaster. Wait... don’t get me wrong. I am not blaming it on the presence of the chemical but the main problem was the absence of the chemical oxazolidines in the paint polyurethane.

Oxazolidines are chemical particles that consist of a range of mono and bis-oxazolidines that hydrolyse on being exposed to moisture yielding reactive amine and hydroxyl functionalities. Therefore, they protect your paint from wearing out in case of a shower, excessive sunlight or other problems. Oxazolidines, when mixed in the paint, keep it together and stable. It is therefore mandatory for all paint dealers to get this chemical component and mix it in the paint in the required proportion.

Unfortunately, my paint dealer was not aware of this and neither did I know about it. However, this year when I got my house re-painted I ensured that I had done my homework right and made sure that the paint dealer had mixed the right amount of oxazolidines in the solution. After all, it always better to be safe than sorry!

Thanks to latent curing agent for sealing my leaking roofs

Have you ever gone through the pain and trauma of a leaking roof? If not then you are definitely lucky, as I was quite unfortunate when this happened to me. It was the spring of 2011, quite an unusual time for rains and more so as I had recently got my roofs and sheds renovated and repainted. One fine evening, to my surprise and shock both together it started pouring first. Soon the mild down pour turned into torrential rains and even before I could react to what had happened I saw my roof leaking from corners.

My son came out running from his room screaming that his roof was leaking, same with my house cleaner who complained of similar leaks in the kitchen. I was taken by shock and felt as if the whole world was coming down crashing and all doors and windows were closing on me. For nearly eight hours it continued to rain and I and my family were locked under a small space where it was not leaking. I did not have the courage to look up to the roof and figure out what went wrong. I could not think of anything all that while. Finally, it stopped raining and as my family finished cleaning, I started calling up people in an attempt to find out what was the problem.

I first called the builder and the architect. They told me it could happen sometimes as the roof maker may have used substandard quality material in making the roofs. I was fuming with anger and called the roof maker immediately, he completely denied and said he had used all good quality products and could even show me the documents. I was at loss for words again. I am a very somber and down to earth person and cannot really fight to prove my point, therefore I consulted with my architect friend and we started our own personal research.

It was after two days of some extensive research that we figured out something about roof coatings and the chemical that is required for that. The common name for the substance used in roof coatings is latent curing agent that is a derivative of the polyutherane and should be used to keep the roof intact. There it was, latent curing agent. I immediately called my roof dealer and asked if he knew about latent curing agent, he replied in the negative and right there I said that I was going to sue him if he does not repair my roof and this time using latent curing agent to do so.

Given my assertiveness and verbal demeanor, he immediately agreed and repaired my roof with latent curing agent. Now, I can peacefully heave a sigh of relief as I am sure that home is protected.
