The Advantages Of Polyurethane Sealants
Aug 27, 2018

 Polyurethane adhesives are industrial adhesives, mainly bonding, sealing and surface treatment. Polyurethane has many advantages, so it has a wide range of applications in construction, transportation, electronics and other industries. Here we introduce one of the polyurethane adhesives. Polyurethane sealant, some of the advantages of polyurethane sealant are described below.


Advantages of polyurethane sealant:


1, single component, room temperature moisture curing, low volatility.


2, high thixotropy, façade and top construction does not flow.


3. It has high tensile strength and excellent elasticity.


4, wear resistance, cold resistance, water resistance.


5, anti-aging and weathering, no corrosion to the substrate, no penetration pollution.


6, good weather resistance, excellent oil resistance, resistant to biological aging, moderate price.


7, the surface can be painted, can be polished.


8, can be bonded to a variety of materials, approved to contact food.


9, low temperature flexibility, performance can be adjusted a wide range, mechanical strength.


10, good adhesion, good recovery, can be suitable for dynamic seams.


11, the service life can reach 15 to 20 years.


12. After curing, the rubber layer is an elastomer, which has good resistance to cold and heat changes and stress resistance.


13. Extensive adhesion to a variety of substrates.
