The potential of MS sealant in prefabricated construction is endless

Prefabricated buildings have entered a period of rapid development, and the total new area is expected to exceed 4 billion square meters in the next five years. In 2019, the total area of prefabricated buildings in China was about 420 million square meters, an increase of 44.64% year on year. The total area of newly built prefabricated buildings accounted for about 13.4% of the total area of newly built buildings, an increase of 3.4pct compared with 2015. In 2017, the "13th Five-Year" prefabricated building action Plan "overall planning provisions, by 2020 all over the country prefabricated buildings accounted for 15% of new buildings, in which the key to promote the region to be higher than 20%, the State Office issued" Opinions on promoting the sustainable and healthy development of the construction industry "provisions, By 2025, the proportion of prefabricated buildings in new construction should exceed 30%. Assuming that the growth rate of the total new construction area in each year of 20-25 years is 2%, and the average share of prefabricated buildings increases by 3pct every year (finally reaching 31.4% in 2025), we calculate that the total new construction area of prefabricated buildings in 2025 will be about 1.1 billion square meters. The 20-25 year CAGR is 17.6%.

Prefabricated building joints are many, promote sealant requirements, we are expected to stimulate in 2025 15-22.2 billion yuan to increase the sealant sales market. According to the silicon treasure technology publicity and set Thai equity survey, the use of prefabricated building sealant is 2 times the traditional use of window and door at the present stage, and the glue requirement per square meter of the total building area is about 1kg. If the total area of prefabricated construction in 2020 is 520 million square meters, it is estimated that it will promote the sealant demand of about 520,000 tons, the market capacity of 71-10.5 billion yuan, according to the previous calculation, if the total area of new prefabricated construction in 2025 up to 1.1 billion square meters, the prefabricated building sealant sales market will reach 15-22.2 billion yuan, With a CAGR of 17.6% in 20-25 years, it is expected to become a faster market segment in the middle and downstream requirements of building sealants.

Prefabricated buildings require higher performance of sealant, MS glue and other performance commodities broad market in the future. Prefabricated building components prefabricated components into the key, the selection of professional design scheme, modular design, processing plant manufacturing and construction steps on the spot installation, prefabricated components after patchwork resulting in a total number of joints, if the sealing moisture is not reasonable very easy to become penetration of the connection point. Due to the surface characteristics of concrete engineering in prefabricated buildings and the factors such as plate migration, it puts forward higher requirements on the adhesive properties, ductibility, weather resistance and scraping property of sealing adhesive. Traditional silicone adhesive used in buildings has good aging resistance and low strain rate (high elasticity and migration ability), but it has weak bonding and scraping property in concrete engineering. And prefabricated building matching degree is not MS sealant.

On August 1, 2018 announced the implementation of the national standard "silicon copper and modified materials silicon copper building sealant" (GB/T14683-2017) for the first time independent listing MS adhesive migration capacity, strain rate, malleable repair rate and other necessary actual judgment values, and establish the modified material silicon copper building sealant is suitable for building lifting restrictions and dry shrinkage offset joints. According to the data information of China Adhesives and Adhesives Industry Association, the market share of MS adhesive in Japanese construction sealant sales market is higher than 50%, and in 2019, Real Madrid Technology plans to invest in the construction of 50,000 tons of MS epoxy resin production capacity (MS adhesive key raw material), is expected to get rid of German Wacke and other foreign enterprises in the technical monopoly of the industry.
