APPLICATION FIELDS
KALI 2000 silicone is suitable for sealing and joining constructions of glass, aluminium, tiles, ceramics, glazed tiles, metals (zinc, copper, etc. ), plastics (PVC, epoxides, polyester, polyacrylate, formica, etc. ), varnished or painted wood, etc.
KALI 2000 IS ESPECIALLY SUITABLE FOR SEALING JOINTS ON POWDER COATED ALUMINIUM FRAMES, ON THE EXTERNAL SIDE OF THE FRAME BETWEEN THE ALUMINIUM AND THE MARBLE.
INSTRUCTIONS FOR USE
CARTRIDGES
The closed cartridge is cut at the point where the thread ends. Then the nozzle is screwed on the cartridge and cut (slantwise preferably) to form an opening proportional to the joint width. After the cartridge has been cut appropriately, the sealant is applied in the joint with the use of a hand- or air-gun.
The sealant must be applied on clean and dry surfaces (without any dust, loose particles, oil, etc. ).
The use of self-sticking paper tape (MASKING TAPE) on both sides of the joint is recommended, in order to avoid soiling.
Immediately after the application of the sealing material in the joint, the surface of the uncured sealant is smoothed with the use of a spatula or by finger.
Restrictions : The width of the joint must be neither less than 3-4 mm, nor more than 30-40 mm.
Precautions : Contact with eyes must be completely avoided. In such case wash with plenty of water. Keep it away from children
Storage stability : at least 12 months if stored in a cool (below 25oC) and dry place.
