Multi-purpose PU Foam SP1900-2
Detailed Product Description
SP1900-2 Spray PU Foam, which is based on moisture curing polyurethane, containing safety propellant, is used to seal gaps and crevices with very high expansion yield UP TO 60~65 LITERS, the post-expansion is quite low to prevent deformation. The foam that dispenses from aerosol can is moisture cured and draws humidity from the air for cure. PU foam is widely used for filling joints between walls, ceilings, floors and gaps around pipes, windows and doorframes. Foam can be cut once fully cured, provides excellent bond to lumber, plywood, concrete, metals, masonry and other substrates.
Features
Economically insulates, fills, seals and bonds
Easy to use
Bonds to and seals most popular construction materials, wood, concrete, plaster, plumbing etc.
Excellent for interior and exterior applications
Durable airtight seal-stops air infiltration, drafts and energy loss
High insulating value-saves energy and money
Usage
Mounting of window and door frames
Sealing of all types of cracks and holes
Insulation of water-pipe network, central heating
Soundproofing of partition walls, car and boat cabins etc.
Operation
PREPARATION FOR USE
Substrate must be clean, firm, free of loose particles and free of dust, grease and mold release agents. Surfaces not to be foamed must be protected. Shake cans well before using.
Application method
1. Shake can well to make the foam ready for use
2. Clean the substrate and spray some water on it
3. Screw foam dispenser on tightly and turn can upside down
4. Vertical fills the gaps from the bottom upwards
5. Foam is tack-free (dry to the touch) in 7 to 15 minutes in temperatures between +18º C and +25º C (65º F~77º F). Higher temperatures will result in faster curing times
6. Remove fresh foam over spray with Sepuna Foam Cleaner or solvents such as acetone. Cured foam can only be removed mechanically.
Remark: For gun/professional foam, an additional foam gun dispenser is needed to spray (Needs to buy separately). In such case, you may also need to buy foam cleaner to clean the gun adapter after use.

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
