Product Detail

Product Tags

Youxing Shark has two component polyurethane adhesive, including pu adhesive and curing agent (MDI). We focus on the innovative application of thermal insulation and decoration integrated board bonding technology. It has applied to composite boards such as expanded polystyrene board (EPS panel adhesive), extruded polystyrene board (XPS panel adhesive), rock wool board (rockwool sandwich panel glue ) and stone composite board. Energy-saving decorative board, perlite, cement foam insulation board and other materials have been researched on the principle of heat insulation, strength, water and weather resistance and construction technology for many years, and continue to innovate and develop suitable products to meet market needs and customize products for customers.

Insulation board bonding adhesive has great fire resistance, great frost resistance, great heat preservation effect, light weight and high strength, also great aging resistance and great sound insulation.





Insulation board

Apply for

building exterior wall panel

Surface material

metal panel, calcium silicate board, stone, ceramic sheet, etc.

Core material

rock wool, foam board (EPS, XPS), extruded board, real gold board, etc.

XPS insulation board

XPS insulation board is a rigid foam board made of polystyrene resin as raw material plus other raw materials and poly-containing materials, heated and mixed with catalyst at the same time, and then extruded and molded. Its scientific name is extruded polystyrene foam (XPS) for heat insulation. XPS has a perfect closed-cell honeycomb structure, which allows XPS boards to have extremely low water absorption (almost no water absorption) and low thermal conductivity. , High pressure resistance, anti-aging (almost no aging decomposition phenomenon in normal use).

Product Features


Stable foaming

The foaming rate is ≥40%, and it has a certain filling effect on core materials with poor porosity and low flatness.


Excellent coating

The machine rolls and does not leak glue (perforated board).


Strong weather

The bonding material can be used for a long time, and the weather resistance of the product meets the JG/T396 standard.


High bonding

It can ensure that the board will not crack and degummed after bonding. Tensile strength ≥0.15Mpa (rock wool bonding inorganic board).


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: How’s 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: How’s 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.


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.

Test Contrast

We made tests to compare our glue and other same functional glue.
