A flame-retardant sealant based on modified polyether polymer
Sealant is a kind of sealing material that can fill the joint and the bonding interface indefinitely, and withstand the displacement and deformation of the joint. It is usually a paste-like material that connects the substrates into a whole after curing. Early sealants were made of dry (or non-dry) viscous materials, such as Zhejiang green, tar, natural (or synthetic) resin, and natural (or synthetic) rubber. There are currently three types of high-performance sealants: polysulfide sealants, silicone sealants and polyurethane sealants. Flame retardant sealant based on modified polyether polymer and its preparation method is a new type of modified sealant. The main chain of this type of polymer is polyether with hydrolyzable silane end groups.
As an adhesive, the key function of structural adhesives is undoubtedly bonding, but compared with other adhesives, what is the difference between structural adhesives? First, non-structural adhesives have low strength and poor durability. It is only used for general and temporary properties of bonding, sealing and fixing, and cannot be used for parts bonding.
Brief introduction of matters needing attention in industrial heavy-duty anti-corrosion coatings
Industrial heavy-duty anti-corrosion coatings generally refer to high-performance coatings that can be used in harsh industrial environments and have a longer anti-corrosion life than conventional anti-corrosion coatings. Industrial heavy-duty anticorrosive coatings can be used for more than 10 years in environments such as chemical atmospheres and marine environments. At a certain temperature, the service life can reach more than 5 years in solvent medium, acid, alkali, and salt. Generally speaking, industrial heavy-duty anti-corrosion coatings have the characteristics of high solid content, long weather resistance, excellent adhesion, convenient construction, thick coating construction, and strong comprehensive performance. And it also has certain temperature resistance, high toughness, high hardness, wear resistance and so on. It can ensure better construction and anti-corrosion life in the industrial zone
Sealant: method and equipment for producing sealant
Sealant refers to a sealing material that deforms with the shape of the sealing surface, does not flow easily, and has a certain degree of adhesion. It is an adhesive used to fill the gaps in the configuration and play a sealing role. It has the functions of leakproof, waterproof, anti-vibration, sound insulation and heat insulation. Sealants are widely used in various modern occasions.
Glass glue: the basic characteristics of glass glue
Glass glue is a very common product in our lives. When we talk about it, everyone is familiar with it. Although it is often used, many users do not understand the basic characteristics of glass glue. Next, the editor will give you a detailed introduction. If you want to know, please feel free to take a look at the editor. I hope to help you.
