SP131 Polyurethane laminated adhesive

　　∎Product Description

　　SP131 polyurethane is a wet curing one component polyurethane adhesive.During the curing process,it will foam and expand,which can flatten the uneven surface.

　　∎Typical Applications

　　It is applicable to the bonding of sandwich panels and skin materials.SP131 has good adhesion to wood,plastic,metal,glass fiber,mineral wool,etc.

　　∎Key features

　　1.Solvent free;

　　2.Low dosage,high strength;

　　3.High expansion and good filling;

　　4.It is easy to use and can be pumped.

　　∎Technical Data Table

　　∎Directions for Use

　　Before use,

　　please be sure to read the material safety data sheet to understand the corresponding preventive measures and safety suggestions.In addition,for chemical products that are exempt from mandatory labeling,relevant precautions should always be observed.Please also refer to the local safety instructions and contact SEPNA for analytical support.

　　This product is only suitable for experienced professional users.Before use,the actual substrate and conditions must be tested to ensure adhesion and material compatibility.

　　Substrate pretreatment

　　The surface must be clean,dry and free of grease,oil,dust and pollutants.After cleaning,physical or chemical pretreatment may be required,depending on the surface and type of material.The type of pretreatment must be determined by testing.

　　Construction

　　Generally,the amount of glue applied is between 100-300 g/m2 according to the type of substrate to be bonded.For a specific base material combination,the amount of glue must be determined by test.

　　SP131 is very suitable for automatic applications.For manual application,after applying with a trowel,spray 10%water mist on the surface,and stick the parts together before the end of the opening time.

　　In order to make the substrate and the adhesive have a void free contact,sufficient bonding pressure is required.The specific pressure depends on the core material and must be determined by test.The pressure must always be lower than the maximum compressive strength of the core material.Once the stamping is started,do not release the pressure until the stamping time is sufficient.

　　Curing

　　The mixture can be cured between 15℃-30℃.The higher the temperature is,the faster the curing speed is.The lower the temperature is,the slower the curing speed is.

　　During the curing process,carbon dioxide is released from the adhesive.If no substrate is porous,measures need to be taken to allow carbon dioxide to escape(for example,cavities in the bonding surface).

　　Cleaning

　　Cleaning agent can be used to remove wet glue,uncured materials(cleaning tools,equipment,substrate pollution,etc.),and the adhesive can only be removed mechanically after curing.
