Cleanroom Panel Bonding / Purification Board Bonding
Youxing Shark's polyurethane adhesive is two component polyurethane adhesive. It is widely applied for cleanroom panels, insulation board, refrigerated transport board, curtain wall, rail interior decoration, steel matal structure material, ship material and fire rated door. For cleanroom panels, youxing Shark focuses on the technological innovation and application of the bonding of the purification and maintenance system. It applies flame-retardant paper honeycomb purification board, rock wool purification board, glass magnesium flame-retardant paper honeycomb purification board, high-efficiency antistatic and antibacterial purification board, aluminum honeycomb manual board, paper honeycomb. After years of research on the process principle of materials such as hand-made boards, the DP hot-pressing adhesive has been innovatively developed, which can meet advanced processes such as spray hot-pressing and spraying hot-pressing. It has a long active period, long open time, and fast curing. It is a purification enclosure system. The preferred products of many outstanding companies in the field.
Purification board, also known as cleanroom board, is a composite board with color-coated board, stainless steel and other materials as the surface material. Because of its unique dust-proof, anti-static, anti-bacterial and other effects, it is widely used in electronics, pharmaceuticals, food, biology, and aerospace. Aviation, precision instrument manufacturing and scientific research and other fields of purification engineering that have strict requirements on the indoor environment.
The purification board can use nine core materials such as rock wool, silica rock, glass silk wool, paper honeycomb, ceramic aluminum board, glass magnesium board and color steel plate, galvanized plate, galvanized steel plate, stainless steel, printed steel plate. There are more than ten kinds of surface materials such as paper, PVC, plywood, fiber cement board, and more than twenty types of composite boards.
Youxing Shark polyurethane adhesive has high fire resistance grade, compressive strength, compressive strength and exellent surface flatness. Many customers choose our adhesive because of great quality and great stability of products.
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 operating time can be long or short, which can meet the needs of customers for various operating time, with strong flexibility.
The bonding material can be used for a long time, and the weather resistance of the product meets the GB/T 7124- 2008 standard.
Easy to brush / easy to spray
For customers' manual squeegee coating, machine coating, spraying, cold pressing, and hot pressing processes, they have good coating effects. The glue is even and the machine is not blocked.
Flatness standard: +0.1mm surface must be clean, oil-free, dry and water-free.
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
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
(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)
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
Pressure requirement: 80-150kg/m², the pressure must be balanced.
The curing temperature is above 20℃, and it can be processed lightly after 24 hours, and can be processed deeply after 72 hours.
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: 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 -20℃Medium 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.
