With the continuous development of China's economy and the accelerated process of urbanization, the rail transit industry has entered a period of great development.
China's new subway mileage, for example, will reach 3000-4000 km, with a total investment of 2.5 trillion - 3.2 trillion RMB. HANSI responds on the rail transportation industry modernization, environmental protection, safety and comfort requirements, with a full range of plastic solutions.
HANSI adhesives are used in all aspects of the rail transportation industry, such as inner door / exterior door bonding, table and chair bonding, equipment cabin floor composite, metal parts, floor, luggage rack, window wall panels etc. Particularity of the rail transportation industry is that all of these bonding parts are constantly moving, which requires high flexibility and high adhesion strength during the period of time.
HANSI’s newly developed durable holding power structural adhesive can meet the needs of the rail transportation industry.
1. The basic requirements of structural adhesives
· Bonding security
· Bonding strength can meet or exceed customer needs.
· Environmentally friendly
· Cost reducing
· Durable adhesion stability, aging resistance and fatigue resistance.
HANSI new products --- durable type PU structural adhesive YEBOND ® 2223
YEBOND® 2223 is a high strength, solvent free, 2K polyurethane adhesive. The main agent is a hydroxyl group-containing prepolymer, and an isocyanate-containing prepolymer.
YEBOND® 2223 can be used for all kinds of sandwich panels in rail transportation, shipbuilding and other industries (such as aluminium honeycomb panels, metal plate and honeycomb core structure bonding).
Epoxy adhesives are those glues whose base polymer is formed by the chemical group known as epoxy, epoxy glues are also known as rigid adhesives or rigid glues, due they possess a high strength or load resistance, about 30 MPa to shear stresses, and very little elongation, over 10% before fracture, these properties are due to the structure of thermoset polymers which adopt the adhesive once it is cured. Epoxy adhesives are classified into 2 groups: · 2-component epoxy adhesive (Epoxy 2C) · 1-component Epoxy Adhesives (Epoxy 1C)View Details
Overview - Contains an epoxy group, for most of the material has a strong cohesive force - Flexible formula design - according to customer requirements to customize the product - Curing into thermosetting plastics - Single component - heat curing - Two-component - room temperatureView Details
one-component modified silane elastomeric binder that can also be used as a two-component material for accelerated curing. The product reacts with moisture and forms an elastomer after curing.View Details
