Bostik Seal N Flex FC:  

Bostik Seal N Flex FC is a high performance fast cure one component polyurethane sealant. When cured it will form a tough, flexible seal and bond capable of cyclic, expansion and compression movement. Joints or fabrications formed with this sealant can be expected to extend and compress a total of 50% (+/- 25%) of original joint dimensions to ASTM C719.

Bostik Seal N Flex FC is virtually unaffected by normal weathering conditions such as rain, sunlight, snow, sleet, ultra-violet radiation, ozone, atmospheric contamination and pollution. Its excellent weather ability enables it to retain its original properties after years of exposure. Its physical properties remain relatively unchanged over a wide temperature range (-40 C to 70 C).

APPLICATION INSTRUCTIONS SURFACE PREPARATION

 

Clean all surfaces by removing foreign matter and contaminants such as oil, dust, grease, frost, water, surface dirt, old sealants and any protective coating. Porous substrates should be cleaned by grinding saw cutting or blast cleaning (sand or water). Dust, loose particles, etc should be blown out of joints with oil free compressed air or vacuum cleaned. Non porous and plastic surfaces should be cleaned by solvent or mechanical means. Cleaning solvents should not be allowed to air dry or evaporate without being wiped with a clean, dry cloth.

 

PRIMING POROUS SUBSTRATES

 

Absorbent or porous substrates will allow a bead of water to easily soak into and wet out the surface of the substrate.

For maximum performance on porous surfaces and, in all periodically immersed and submerged applications, use Bostik N49 Primer, or one coat of Bostik MVP525.

Porous substrates not subject to immersion or ponded water, e.g. vertical expansion joints in concrete or masonry structures, do not require priming if clean, dry and uncontaminated.

 

PRIMING NON POROUS SUBSTRATES

 

Non-absorbent substrates will cause a bead of water to be retained on the surface of the substrate as a raised droplet. The droplet does not easily soak into the surface of the substrate.

Bostik MVP525 is recommended for non-porous or burnished/overworked concrete substrate as per Bostik MVP525 Technical Data Sheet.

Bostik N40 Primer is recommended for non-porous plastic and metal substrates.

Prime all plastics and metallic non-porous substrates with Bostik N40 Primer using the two-cloth method described below.

E.g. UPVC outlets and pipe work: brass, copper fittings, stainless steel trays and flashings

 

TWO CLOTH METHOD - N40 PRIMER APPLICATION

 

Dampen a clean and dry cloth with Bostik N40 Primer and spread evenly over the non-porous substrate using a cleaning/rubbing action.

With a second clean and dry cloth, immediately wipe all primer residues off with a buffing action.

Allow the substrate to dry for a minimum of 5 minutes before installing Bostik Seal N Flex FC.

Do not leave the primer longer than 4 hours before applying sealant/adhesive.

Re-prime if 4 hours has elapsed without applying sealant/adhesive

Clean and re-prime if the primed surface is contaminated before Bostik Seal N Flex FC is applied.

 

APPLICATION

 

Bostik Seal N Flex FC when used as an adhesive or sealant should be dispensed from either the cartridge or sausage sachet by means of a hand or air operated caulking gun designed for such application (available from Bostik). Pierce the membrane from the top of the cartridge and screw on the supplied nozzle. Having previously cut this to give the required angle and bead size. Place the cartridge in a suitable Bostik extrusion gun and press the trigger. For sausages, a barrel gun is required, this is available from Bostik. Clip the end of the sausage and place complete sausage with pierced end located at the top of the nozzle. Screw top of nozzle and housing on barrel of gun. Using the trigger on the gun extrude product from the sausage to stop product flow, using the thumb depress the catch plate mechanism located at the very rear of the gun, directly above the trigger. Apply Bostik Seal N Flex FC in a continuous operation using positive pressure adequate to properly fill and seal a cavity.

 

CONSTRUCTION ADHESIVE APPLICATIONS

 

Bostik Seal N Flex FC does not need to be applied to both surfaces to be bonded, but both surfaces must be prepared in accordance with preparatory work. Apply in beads or daubs to the prepared substrate. Materials being adhered can be bonded immediately or left open for up to 15 minutes after application prior to bonding. If no mechanical fixing is to be used in conjunction with adhesive, clamping is necessary until full cure is achieved. Use only enough sealant to achieve adequate bond (dependant on surface texture). Excess sealant can be removed by dry cloth or solvent wipe before curing. If adhesive is to be exposed, smooth off with spatula or putty knife to flush finish.

 

CONSTRUCTION SEALANT APPLICATIONS

 

Bostik Seal N Flex FC is especially suitable for vertical joint sealing or in flooring applications such as saw cuts jointing. More joint movement can be accommodated in a thin bead of sealant than in a thick bead. The ratio of joint width of sealant to depth should be 2:1. The use of a bond breaker prevents undesirable three-sided adhesion. Open cell polyurethane foam or closed cell polyethylene foam rod is the recommended back up material to control correct sealant geometry. Install back up material or joint filler, as specified. Apply Bostik Seal N Flex FC continuously using positive pressure to properly fill and seal the joint. Tool the sealant with adequate pressure to spread the sealant against the back up material and onto the joint sides. Excess sealant should be wiped from all surfaces while still uncured. Remove any masking tapes prior to sealant curing

 

JOINT SEALING HINTS

 

Always use backing rod for correct sealant geometry & contact with the substrate.

Prime after the installation of the backing rod.

Ensure maximum adhesion to bond face and depth to width ratio of 1:1 up to 12mm and 1:2 from 12 - 50mm.

Tool sealant to achieve concave shape

 

MIXING

 

No mixing is required, simply use directly from cartridge or sausage
