Fosroc Nitoseal PU400 Sealant 600ml

Product Description

Fosroc Nitoseal PU400 Sealant is a tough, abrasion resistant, one component, trafficable, polyurethane joint sealant. It is ideal for bonding or sealing joints between most construction materials, where high bond strength is required. It is fast curing, will not stain, and is ideal for wide floor joints and water immersed applications. PU400 has excellent primerless adhesion to most materials and is suitable for wet applications when coupled with a primer.

Features:

• Suitable for use as a sealant or adhesive
• Ideal for wide floor joints
• Tough and abrasion resistant
• Suitable for foot and light vehicle traffic areas
• Excellent primerless adhesion
• Fast curing
• Low stringing
• High gunning rate for enhanced productivity
• Suitable for water immersed applications when used with appropriate primer (see Technical Data Sheet for more information on priming)

Ideal for:

• Trafficable floor joints
• Metal or concrete water retaining structures
• Assembly of metal framed buildings
• Cover plates and covings
• Bolted lap joints
• Sealing pipe penetrations in walls and floors

APPLICATION

Surface Preparation:

The joint surfaces must be thoroughly dry, clean and frost free. Remove all dirt, laitance, curing compounds, form release agents, loose materials and foreign matter from the joint faces. Remove all rust, scale and protective lacquers from metal surfaces. Non-porous surfaces should be degreased. In all joints a bond breaker must be used to prevent sealant contact with the back of the joint, to allow optimum sealant performance.

Priming of porous substrates is always recommended, however good adhesion can be gained on concrete, timber, metals, ceramics, brickwork and most coating surfaces without the use of primers. Adhesion is improved with use of a primer. To achieve optimum adhesion to concrete and other porous materials use Primer 21; on non-porous materials such as metals use Primer 4. Primer 13 must be used on porous surfaces if the Nitoseal PU400 is to be water immersed.

Placement:

Insert the sausage into the gun, cut a slit at the top of the sausage, replace the end cap and nozzle and apply the sealant. Extrude the sealant firmly into joint to ensure complete contact with joint faces. Tool the sealant into the joint.

Clean Up:

Clean tools immediately after use with solvent.

Storage:

Shelf life 12 months. Store in a cool dry place.

Yield:

On average one 600 ml sausage will supply 3 metres of 20 x 10 mm sealant bead.
