Date: 2011-03-15   Author: Polyurea.cn

Struck by the harmful effects of fake polyurea, let's review the article on CHINA CONSTRUCTTON NEWS of June 30th, 2009, which was written by Prof. Huang of Qingdao technological university, as well as the comments given by Haitao Zhang, the journalist. Being astonished by the serious hazards fake polyurea made in the jobsite, we'll profoundly sense of the importance of respecting (the) science and seeking (the) truth from the facts.

At the 15th annual conference of China Polyurethane Industry Association on November, 11th, 2010, Prof. Huang delivered a speech,elaborating the scientific origin and chemical definition of polyurea clearly, and severely criticized the so-called "semi-polyurea"?which totally distorted the scientific definition of polyurea. This speech has given the audience a shock. Later on, magazines such as Polyureathane Industry, Shanghai Coatings, Coating Industry, Modern paints & Finishing were asking for more manuscripts, and they all actively response to the call of, resolutely resisting the fake polurea.

As a special report of "3.15 The World Consumer Right Day"? we selected the following typicalphotos of fake polyurea projects from those victims, as a reminder for all the consumers to take an active part in QTG training(See www.polyuea.cn2011-02-08 News), master the skills of distinguishing the fakes from the pure polyurea and the proper application process, and make your projects a real durable and perfect one by using the pure polyurea!
