Foreword to the Column：
Who is Sinochem Dongda? We are a comprehensive supplier of high-end polyether polyols.
Within the polyurethane industry, polyether polyols and their premixed formulations are commonly referred to as the "white component". Dongda “White Tech” represents innovative raw material technology featuring high performance, green low-carbon development, cleanliness and safety — the technological code that makes life safer, purer and more durable.
As technology evolves, polyether polyols have been widely applied across production and daily life. Charming Sinochem Dongda launches the column Dongda “White Tech”. We will guide you to explore diversified application scenarios of polyether polyols, interpret core product properties, discover technological power around us, and experience how innovation delivers a better life.
Why do some daily goods wear out easily, while others stay bright and new for a long time?
Scratch-resistant phone casings, crystal-clear furniture paint films, and colorfast printing on various packages… Such products maintain exquisite appearance year after year, thanks to an invisible yet highly reliable protective coating.
This coating requires no slow air-drying or high-temperature baking. Upon exposure to ultraviolet light, it solidifies instantly to form a firm and durable layer. Nail lamps in nail salons, for instance, fully cure nail polish within dozens of seconds to prevent smudging and peeling. UV curing technology also delivers long-lasting protection for many daily commodities.
What makes this popular process outstanding, and which raw materials guarantee stable performance? The answer lies in Sinochem Dongda’s “White Tech”.
Sinochem Dongda offers a wide range of polyether polyols specially designed for UV curing, including polyethylene glycol (PEG), glycerol, trimethylolpropane (TMP) and bisphenol A (BPA) series. These products can be used to manufacture key materials such as UV coatings, inks and adhesives, providing stable and high-performance raw material support for industries. Let’s take an in-depth look.
The most prominent advantage of UV curable polyether polyols is ultra-fast curing. The material cures within seconds under UV irradiation, greatly shortening production cycles. It fits seamlessly into high-speed automated production lines to boost output and delivery efficiency.
With excellent flexibility and bending resistance, cured coatings resist cracking and peeling. They deliver durable protection for flexible substrates and articles subject to repeated bending, effectively extending product service life.
Low-VOC emissions are achieved at the raw material source. No small molecule volatiles are released during curing. Free of formaldehyde and solvents, the materials do not require mandatory ventilation at work sites. Certain modified grades feature low skin irritation, meeting environmental standards and better safeguarding occupational health and safety of operators.
Liquid at ambient temperature, the products feature low viscosity and favorable fluidity, enabling uniform coating free of bubbles and pinholes with consistent thickness. Especially for precision applications including optical fiber coating and display bonding, low viscosity ensures superior process adaptability and stable product quality.
The materials boast excellent resistance to chemical corrosion and weathering, capable of withstanding acids, alkalis, solvents, oil stains and other harsh media. Even under prolonged outdoor and industrial exposure, coating performance remains stable without fading, deformation, chalking, cracking or failure.
Do not regard them merely as coating raw materials. Their application scope is far broader than you imagine.
Benefiting from fast curing, high flexibility, low VOC, low irritation, strong chemical resistance and adhesion as well as easy processing, UV curable polyether polyols are adopted extensively in electronics, architectural coatings, printing & packaging, automotive industry, 3D printing, optical fiber communication and other sectors.
In the electronics industry with stringent precision and reliability requirements, UV curing technology satisfies the core demands of speed, stability and cleanliness for chip encapsulation, PCB conformal coating, connector protection and display bonding.
In daily applications, it is used for flexible UV coatings on leather and paper, surface finishing of auto parts, and 3D printing materials. It performs steadily on flexible and rigid substrates alike, both indoors and outdoors.
Furthermore, UV curable inks applied to label printing, plastic card printing and high-end packaging dry instantly with vivid colors free from smudging, becoming a vital solution to improve efficiency and quality in the printing industry.
Sinochem Dongda “White Tech” empowers every moment of life.
From the UV beam of nail lamps, high-efficiency coating lines on production floors, to precision components formed layer by layer via UV curing 3D printing, Sinochem Dongda consistently takes technological innovation as its core driving force. Upholding the pursuit of premium quality, we keep expanding our diversified application portfolio and forge ahead with professionalism and craftsmanship.
