An epoch-making product of sealant industry-- polyaspartic polyurea sealant

The proper name of sealant is surface decorative joint adhesive, which is an upgraded product of sealant. Sealant is better than color sealant in both decoration and practicality. It effectively solved the problems that ceramic tile gap is not beautiful and easy to be messy.


The traditional sealant is made of epoxy resin, but in recent two years, a polyaspartic polyurea sealant has appeared on the market, which is made of polyaspartic polyurea resin. Due to the excellent performance of polyaspartic polyurea sealant, it has been recognized by many consumers as soon as it comes into the market. It makes the sealant industry have epoch-making products, so many well-known brand manufacturers have begun to invest in the research and development and sales of Polyurea sealant.



So, why does polyaspartic polyurea sealant have such charm? Why can it replace epoxy sealant, become a new generation of ceramic tile sealant?


Although epoxy sealant is rich in color, its use performance and decorative effect are also good, which can meet the basic needs of people for the beauty of home decoration. However, it has always had one unavoidable drawback - it tends to turn itself yellow and fall off. In this case, a non-yellow and weather-resistant new sealant - polyaspartic polyurea sealant came into being.

As shown in the figure, under continuous ultraviolet radiation, the epoxy sealant appeared serious yellowing phenomenon. And even on the fifth day, it had serious cracking phenomenon, while the polyaspartic polyurea sealant sample was remaining as white as the original appearing.


  • Why does not polyaspartic polyurea sealant turn yellow?


Epoxy sealant is made of epoxy resin. The inevitable yellowing of epoxy resin is determined by the benzene ring structure. However, polyaspartic polyurea sealant is made of aliphatic materials, and its material structure has no yellogenic group. So, no matter how the sun exposure, polyurea sealant can remain as white as new!


  • On the fifth day, epoxy sealant cracked seriously, while polyurea sealant was still flawless. Why is this?


The experiment found that the brittle crack of epoxy material, which is caused by the addition of plasticizer in the production process. Polyurea material itself has the characteristics of high solid content and low viscosity, so there is no need to add any plasticizer in the production process.



In addition to the above advantages, polyaspartic polyurea sealant has the advantages of environmental protection and odorless. Compared with epoxy sealant, the advantage of polyaspartic polyurea sealant is also recognized by most consumers.


Anyone who has used epoxy sealant knows that epoxy sealant come with a very pungent taste, which is the smell emitted by free ammonia generated during the synthesis of its curing agent. This is an unavoidable problem as turning yellow. However, polyaspartic polyurea sealant completely solves the problem from the root cause, because there are no odor-producing free substances in the hardener and resin. According to the third-party testing report, polyaspartic polyurea sealant can perfectly meet the requirements of EU A+ environmental standards.
