Description
SP21X series products are Two-component polyurethane adhesive which cures by chemical reaction of the Two-component mainly designed for corner connection application.
SP21X series products are used for bonding e.g. corner connections for frame profiles that are usually used for windows and doors.Fast-curing two-component solvent-free polyurethane adhesives for corner connection of aluminum doors and windows
▪ UV colour retention
▪ Solvent-free
▪ Thixotropic, does not drop off
▪ Good weather ability

Cure Mechanism
The curing of SEPNA SP21X takes place through a chemical reaction of the two components. Higher temperatures speed up the curing process and lower slow it down.
In big bead applications, the generated heat of exothermic reaction can speed up the cure, reducing the pot life.
Method of Application
Surface Preparation
Surfaces must be clean, dry, and free from grease, oil, dust, and contaminants.
After the cleaning process, a physical or chemical pretreatment might be required, depending on the surface and type of material. The type of pretreatment must be determined by tests.
APPLICATION SEPNA SP21X is dispensed by piston guns adequate for 620 ml 1:1 side-by-side cartridges.
For application out of the cartridge, the extrusion force must not exceed 3.3 kN. Extrude adhesive without a mixer to equalize the filling levels.
Attach the mixer and dispose of the first few cm of the bead prior to the application. Check the color of the adhesive and make sure it is mixed properly (no strings or stripes in the extruded bead). The mixer must be changed if the application is interrupted for longer than 7 minutes.
Package specification: Double tube plastic cylinder packaging (equipped with static mixing nozzle) 600ml/PCs, 12 PCS/ box | Storage:SEPNA SP21X has to be kept between 10 °C and 30 °C in a dry place. Do not expose it to direct sunlight or frost. After opening the packaging, the content has to be protected against humidity. The storage period is 9 months from the production period | Transportation: moisture-proof, rainproof, sunproof, high-temperature roof, keep away p from heat sources, handle with care, and do not squeeze or collide |
