Oxazolidines – Delivering great performance across various industries

by Deepika Olive SEO Executive
An oxazolidine is a five-membered ring compound made up of thee carbon, one nitrogen and one oxygen. The oxygen and NH are the 1 and 3 positions, respectively. It is studies that oxazolidine derivatives always contain a carbon between the oxygen and the nitrogen. Over the past few years, a number of technical advancements have taken place that has completely transformed the industry and made a considerable effect on the solvent-borne industrial coatings industry. In addition, the stringent VOC regulations have led to the evolution of a more feasible water-based alternative to solvent-borne technology.

The modern technology not only hits the water based technology but also the high solids coatings industry. These technological advancements are typically executed with lower molecular weight compounds to achieve the least possible viscosity with the limited solvent usage. It is important to notice that there is a specific limit to molecular weight reduction, and sometimes it can lead to issues related with the loss of coating performance. For example, the 2-pack polyurethane coatings market has witness this change. Generally, these systems comprise of acrylic polyol and and HDI-based polyisocyanate. These lead to polyurethane dispersions unique performance qualities including superb chemical resistance. Hence, one solution to sustain the coating benefits of solvented systems, whilst reducing the VOC, is to include in a reactive diluent.

The presence of water and moisture in one-component moisture heals polyurethanes lead to poor in-can stability. In the similar way, moisture in isocyanates sometimes leads to the creation of CO2 which dissolves in the product and can subsequently cause foaming when the container is opened. In highly precise cases, these containers may begin to bulge and lids get burst as an outcome of high vapor pressure. Oxazolidines act as an effective reactive diluent and features numerous benefits. First, it offers excellent polyol and solvent compatibility. They contain low intrinsic viscosity - 50 mPas@20°C. In addition, it has considerably high equivalent weight. Its low color allows for clear lacquer finishing. There finds zero side effects on the coating properties including film hardness development and resistance, gloss and weathering properties. Its applications include low VOC paints and varnishes, top build paints and elastomers.

Oxazolidines are largely used to emulsify and harden both liquid and solid epoxy resins, yielding tough, durable polymers. This is one of the foremost reasons why this material is in high demand from various industries that can’t survive without epoxy curing agents.

Searching for Oxazolidines? The Incozol series of oxazolidines consists of a range of mono and bis-oxazolidines, which hydrolyse on exposure to moisture yielding reactive amine and hydroxyl functionality.
