A polyurethane dispersion with a bio-based content of 18.5% and strong film-forming properties - Hou

From 2020, when China first made a solemn commitment to the world of "carbon peaking and carbon neutrality", to 2021, when the "dual carbon" strategy was incorporated into the overall layout of ecological civilization construction, the "dual carbon" demonstrated China's determination to develop green. .

As a firm practitioner of the "double carbon" strategy, Guangdong Huaguoshan Environmental Protection Technology Co., Ltd. focuses on environmental protection, with the concept of technological innovation and the pursuit of the ultimate, and launched the bio-based water-based wood varnish resin - Houxian® U310, its Its physicochemical properties are comparable to those of petroleum-based resins, and it is a star product that helps the paint industry and furniture companies transform from oil to water.

Houxian® U310 basic parameters

Outstanding physical properties

From the test in the table above, we know that Houxian® U310 has good film-forming properties, good storage stability, good compatibility with solvents, and excellent film flexibility.

Excellent film-forming properties

(Scratch 120μm wet film on glass plate)

As can be seen from the above figure: Houxian® U310 can help acrylic emulsion form film, reduce the amount of film-forming aids, and reduce the VOC of coatings, thereby achieving energy saving and emission reduction.

强大的耐化学品性能

单组份（榉木+底漆×2+面漆×1）：

双组份（+5%异氰酸酯固化剂，榉木+底漆×2+面漆×1）：

It can be seen from the above test: Houxian®U310 has high construction latitude, and can be used as one-component or two-component, and the chemical resistance of single-component and two-component is very outstanding.

出色的摆杆硬度

Comparison of pendulum hardness: Houxian® U310 has obvious improvement in hardness no matter whether it is self-drying or drying, especially after adding 5% curing agent, the hardness is even better.

Based on the comparison of the above tests, it can be seen that the comprehensive performance of the bio-based Houxian® U310 is better than that of the traditional petroleum-based paint. The bio-based water-based paint products made of Houxian® U310 resin, with excellent film permeability and flexibility, better present the natural feel of the log texture and excellent surface performance, and calmly cope with high and low temperature in different weathers. The risk of cracking of the paint film caused by the cycle makes wooden furniture easier to care for and prolongs its lifespan.

Driven by environmental protection policies, the transformation of paint companies and their industrial chains to green development is imminent. Huaguoshan Environmental Protection Technology is in line with the development of the "Double Carbon" strategy, seizes the environmental protection needs of customers, uses bio-based paint science to brighten the future, makes products more "green" and more efficient, and provides customers with one-stop overall solutions .
