Product Detail

The curtain wall is the outer wall of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large and high-rise buildings. Youxing Shark conducts technical research on the characteristics and composite bonding technology of materials such as stone, glass, aluminum veneer, aluminum-plastic panel, clay board, and sunshine board for building decorative curtain walls, and innovates and develops a high-strength, high-weatherability. Polyurethane adhesive can meet the needs of architectural decoration curtain walls.The column (or beam) of the component curtain wall is first installed on the main structure of the building, and then the beam (or column) is installed. The column and the beam form a grid, and the panel material is processed into unit components in the factory, and then fixed on the column and beam. On the sash. The load borne by the panel material unit component must be transmitted to the main structure through the column (or beam). Also curtain wall includes unit curtain wall, point-supported curtain wall, full glass curtain wall, intelligent breathing curtain wall, photoelectric curtain wall, curtain wall steel structure, metal roof.

Building curtain wall refers to the non-load bearing outer wall enclosure of a building, usually composed of panels (glass, metal plates, stone plates, ceramic plates, etc.) and supporting structures (aluminum beam columns, steel structures, glass ribs, etc.).The building curtain wall is composed of a supporting structure system and panels, which can have a certain displacement ability relative to the main structure, and does not share the building envelope or decorative structure that the main structure is subjected to.The curtain wall is the outer wall of the building. It is not load-bearing and hangs up like a curtain, so it is also called a hanging wall. It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is a building envelope structure that is composed of a structural frame and inlaid panels, and does not bear the load and role of the main structure.

Product Features


Curable at room temperature/ curable by heating

The active period is long, the product viscosity range is wide, and the high-quality curing effect can be achieved under a variety of temperature conditions.



The cohesive strength of the adhesive layer and the adhesive strength between the adhesive layer and the bonded surface are high. It can ensure that the plates will not crack after bonding, and the tensile strength is ≥6Mpa (aluminum plate is bonded to aluminum plate).


Flexible construction

For customers' manual squeegee coating, machine coating, spraying, cold pressing, and hot pressing processes, they all have good coating effects. The glue is evenly distributed and the machine is not blocked.


High bonding

It can ensure that the plates will not crack after being bonded, and the tensile strength is ≥6Mpa (aluminum plate is bonded to aluminum plate)

Operation Specification

STEP 01 The surface of substrate should be flat and clean.

Flatness standard: +0.1mm surface must be clean, oil-free, dry and water-free.

STEP 02 The ratio of adhesive is critical.

The supporting roles of the main agent (off-white) and curing agent (dark brown) are executed in corresponding proportions, such as 100:25, 100:20

STEP 03 Stir the glue evenly

After mixing the main agent and the curing agent, stir evenly quickly, and use a stirrer to repeatedly pick up the gel 3-5 times without silky brown liquid. The mixed glue will be used up within 20 minutes in summer and 35 minutes in winter

STEP 04 Standard of the amount

(1) 200-350 grams (materials with smooth interlayer: such as inorganic boards, foam boards, etc.)

(2) 300-500 grams for delivery (materials with interlayer porous: such as rock wool, honeycomb and other materials)

STEP 05 Sufficient pressurization time

The glued board should be compounded within 5-8 minutes and pressurized within 40-60 minutes. The pressurization time is 4-6 hours in summer and 6-10 hours in winter. Before the pressure is relieved, the adhesive should be basically cured

STEP 06 Sufficient compression strength

Pressure requirement: 80-150kg/m², the pressure must be balanced.

STEP 07 Set aside for a while after decompression

The curing temperature is above 20℃, and it can be processed lightly after 24 hours, and can be processed deeply after 72 hours.

STEP 08 Gluing equipment should be washed frequently

After the glue is used up every day, please clean it with dichloromethane, acetone, thinner and other solvents to avoid clogging of the glued teeth and affect the amount of glue and the uniformity of the glue.


Q: Are you manufacturer or trading company ?

A: We are manufacturer focused on adhesive for 20 years. So we have more competitive price than trading companies. We also have professional overseas team to provide service for you.

Q: Is your polyurethane adhesive two component ?

A: Yes. Our pu adhesive has two parts, including polyol resin and curing agent.

Q: Hows your packing of adhesive ?

A: Pu adhesive has two packing, one is 25kg/barrel. Another is 1500kg/plastic drum.

  Both two packing will match corresponding curing agent together.

Q: Where is your factory? 

A: We have two production base, Shanghai and Zhuhai. We have 190000 tons annual production capacity in total. Both of them are near shipping port.

Q: Hows the testing result ?

A: 1.Tensile shear strength test is 9.9MPA. Flexural strength 575MPA.

    2. Freeze-thaw resistance test report is 30 circles. (After Soak in water at room temperature for 8 hours, then put it in a low temperature test box at -20Medium freezing for 16 hours, two steps are one cycle, one cycle is 24 hours.)

    3. SGS report shows all of our adhesive is environmental-friendly.

    4. For other test results, please contact our sales for more details.
