NOTE: For the installation of NTF type AerFusion Eco it is not allowed to weld the clearance between two pieces of the NTF. It is approved to seal the NTF with Silicone Sealant-Non Textile Floor Jointing One part - (Material No.06BQD1) .

(3) Weld the clearance between two pieces of the NTF (3):

Welding Procedure

NOTE: This procedure is only applicable for PUR or PVC NTF. It is not applicable for silicone NTF.

(a) Chamfer the edges of the NTF at the joints with a SCRAPER - TRIANGLE SHAPE.

CAUTION: DO NOT CAUSE DAMAGE TO THE MOISTURE BARRIER FOIL (MYLAR).

(b) Make a groove in the shape of a "V" with an angle of approximately 30 deg. on the NTF edges.

NOTE: A stainless steel or aluminum flexible ruler helps to make a straight groove.

(c) Make sure that the groove is not deeper than 2/3 of the NTF thickness.
(d) Remove loose particles with a VACUUM CLEANER.

WARNING: WHEN YOU PUT THE HOT AIR BLOWER DOWN, MAKE SURE THAT YOU PUT IT ON A HEAT-RESISTANT SURFACE. THE HOT PARTS OF THE BLOWER CAN CAUSE A FIRE.

WARNING: MAKE SURE THAT THERE IS A GOOD FLOW OF AIR THROUGH THE WORK AREA. FUMES FROM WELDING ARE POISONOUS.

WARNING: DO NOT TOUCH HOT PARTS WITHOUT APPLICABLE GLOVES. HOT PARTS CAN CAUSE AN INJURY.

(e) Obey the manufacturer's instructions when you use the hot air blower.
(f) Set the working temperature on the HOT AIR BLOWER MAX OPERATING 370 DEG C (700 DEG F) between 160 deg.C (320.00 deg.F) and 200 deg.C (392.00 deg.F).
(g) Cut the welding rod Cord-Welding PVC - (Material No.14RCB1) some centimeters / inches longer than the necessary length.

CAUTION: MAKE SURE THAT:

THE TEMPERATURE OF THE HOT AIR BLOWER IS NOT TOO HIGH
THE BLOWER DOES NOT MOVE TOO SLOWLY ALONG THE WELD.

HIGH TEMPERATURES OR SLOW MOVEMENT OF THE HOT AIR BLOWER CAN BURN THE MATERIAL.

(h) Put the welding rod into the inlet of the speed welding nozzle.
(i) Move the speed welding nozzle with light pressure and constant speed along the groove.
(j) Make the welded joint smooth.
(4) Apply sealant:
(a) Make sure that the NTF surface is dry, dust and oil free. If necessary clean it with Non Aqueous Cleaner-General - - (Material No.08BAA9) and a Textile-Lint free Cotton - (Material No.14SBA1) .
(b) Install Adhesive Film Tape-Masking - - (Material No.05RDA1) around the edges and cutouts of the NTF, where the primer will be applied.
(c) Apply primer:

NOTE: The primer is not necessary for sealant in clearances between silicone NTF.

(d) Apply Adhesion Promoter-For Silicone Sealant - - (Material No.06PBG1) (4) with a Textile-Lint free Cotton - (Material No.14SBA1) :

Into all clearances between the NTF (3) and the furnishing (toilet, galley, etc)
Around all NTF contours
Around all cutouts.

(e) Apply a bead of Silicone Sealant-Non Textile Floor Jointing One part - (Material No.06BQD1) (4) to:

All clearances between the NTF (3) and the furnishing (toilet, galley, etc)
All cutouts.

(f) Remove the unwanted sealant with a SPATULA - NON METALLIC immediately.
(g) Remove the masking tape.

NOTE: The curing time for the sealant, for 2 mm (0.0787 in.) to 3 mm (0.1181 in.) thickness, is 24 hours.
