Advantages and disadvantages of single-component polyurethane sealant
Water-swellable waterstop glue is also called single-component polyurethane sealant, so what are the advantages and disadvantages of single-component polyurethane sealant, let's go to understand with the editor of Hengshui sealant manufacturer
The advantages of single-component polyurethane sealant are as follows:
Advantages 1. Polyurethane sealant is a single-component coating, has strong tensile strength, and has high stability, low odor, and less pollution to the environment. It is a new type of environmentally friendly material.
Advantage 2. It has high thixotropy, even when it is used on an upright surface or the top, it will be very stable and will not flow, affecting the use effect. yfkj01
Advantage 3. Wear resistance, cold resistance, and no corrosiveness to other materials, so polyurethane sealant can be used on most materials.
Advantage 4, the surface can be painted, polished, etc., will not affect the effect of polyurethane sealant.
Advantage 5, has a strong resistance to aging, so the service life can be as long as 15 to 20 years.
Polyurethane sealant has good elasticity and stretchability, and is wear-resistant, cold-resistant, and oil-resistant. Therefore, polyurethane sealants are widely used in construction, electronics, transportation, etc.
So what are the shortcomings of single-component polyurethane sealant, Hengshui Yifeng Technology Editor also introduced to you:
Disadvantages 1. It is not heat-resistant and cannot be used in a high-temperature environment for a long time, otherwise it will affect the time effect, cracks, bubbles, etc. Long-term exposure to ultraviolet rays will also affect the life time.
Disadvantages 2. When using polyurethane sealant in some occasions, primer coating is required and cannot be applied directly.
Disadvantage 3. Polyurethane sealant has poor water resistance, especially alkali resistance. If it is in the environment of alkaline water, it will greatly affect the use effect.
The editor introduced whether you have any understanding of single-component polyurethane sealants. If you are looking for a qualified supplier, then Hengshui Yifeng Technology Co., Ltd. is a good choice for you. Our company is prepared for unexpected needs.
