Product Description


Ruida waterproof polyurethane sealant for construction joint

polyurethane sealant


One component polyurethane sealant is widely used in civil construction, transportation and other industries:
1) in the construction of the application - doors and windows, glass, such as filling and sealing;
2) in civil applications, highways, bridges, runway caulking sealing;
3) in the automotive application window (mainly the windshield) seal assembly.
Sealant is used to fill the voids (holes, joints, joints, etc.) of the material, both bonding and sealing  are the two major functions. Polyurethane sealant ,silicone sealant and polysulfide sealant consists of three varieties of high-grade sealant .

 1) Joint Design
Correct joint design can assure the lifetime of buildings and sealants. To keep the flexibility of the joints, the minimum width of the joints is 5mm. The depth is 1/2 of the width. The recommended width of the joint is 80-100% of the width if the width is less than 10mm.
In order to assure the designed movement capability of the sealant, we should use back lining. Recommended depth of the joint is no less than 5mm.
2) Surface Treatment
The surface should be clean and dry. The concrete placement should be dried for 28 days.
After rainfall, it should be aired for 2-3 days. The water content of the substrates should be lower than 9%. Dryness and cleanness can assure the bonding strength to the substrates.
The surface should be clean without dust, oil or loose layers. Metal surface should be of no oil, rusty stains. If the surface is with cladding material or protective layer, we suggest test the sample.
3) Applying the sealant
Use the brush to clear the surface to make the joint achieve the above requirement.
For good appearance, adhesive tape can be used to paste on two sides of the joint. The edges of the tape should be even with the joint edges.
Pierce the nozzle with an appropriate size at 45°angle. Put the sealant into an applicator gun and squeeze the trigger uniformly into the joint. The sealant should be filled into the joint and overflow a bit in order to avoid hollow space in the sealant.
4) Appearance Treatment
Use the scraper and moisten a bit water to press and scrape flat the surface of the sealant. Take off the adhesive tape. Do not touch the surface of the sealant before within its tack-free time.
