MF840 and mf881 both passed the European standard en1279 insulating glass scale test
as early as March 2007, Zhengzhou Zhongyuan applied technology research and Development Co., Ltd. entrusted a powerful European testing institution to test MF840 polysulfide insulating glass sealant and mf881 two-component silicone structural sealant of Zhengzhou Zhongyuan applied technology research and Development Co., Ltd. according to en1279 scale, During this period, the long-term test method and required periodic test of water vapor penetration and seepage of en insulating glass, the long-term test method and required test of gas leakage ratio and gas concentration deviation of en insulating glass, and the test of physical properties of edge sealant products of en insulating glass were completed, and all of them met the scale requirements. (according to the standard requirements, establish the red and yellow card warning mechanism for product quality. In the en standard test, the insulating glass needs to be filled with argon, and the gas concentration is required to be greater than 85%)
while testing the mf881 two-component silicone structural sealant of Zhengzhou Zhongyuan applied technology research and Development Co., Ltd. according to the en1279 standard, the consumption is more than 70million tons. According to the European certification guide etag002 structural sealant assembly system, carry out the relevant physical function test on mf881, The test project involves many aspects, and the requirements are more stringent, such as tensile bond strength, shear strength, NaC1 environment, SO2 environment, elastic recovery rate, shrinkage rate, mechanical fatigue and so on
passing the test of en1279 and etag002 will help the company improve product quality, enhance market competitiveness and integrate with the international market faster
