WSS SealProof 600ml Sausage Modified Polymer Sealant

WSS SealProof 600ml Modified Polymer Sealant

SealProof is a moisture curing, industrial grade, high performance sealant based on solvent and isocyanate free, MS polymer technology. Displaying high early strength and flexible properties SealProof is ideally suited for commercial and industrial applications where fast bonding, high movement and vibration absorbing qualities are required. SealProof is suitable for internal and external applications providing outstanding UV resistant and anti-aging characteristics.

Features and Benefits

• User and environmentally friendly – contains no solvents isocyanates, acids or halogens
• Permanently elastic
• Highly flexible
• Low emissions
• Good adhesion on both porous and non-porous substrates
• Excellent durability
• Good weathering resistance, colour stability and UV resistance
• Suitable for use on damp surfaces with no bubble formation
• Good extrudability
• Odourless
• Paintable – see notes
• Colourfast – Non staining
• Does not support fungal growth
• Environmentally friendly

Recommended Use

• General sealing and bonding of construction elements
• Material assembly where a tenacious elastic adhesive is required.
• Elastic bonding in vibrating constructions
• Concrete expansion joints
• Masonry control joints
• Sealing where acoustic properties are required
• Perimeter sealing around window and door frames
• Sealing of penetrations in walls or floors
• Sanitary applications

Substrates

• Concrete and masonry
• Ceramics, stone, granite, and marble
• Metals including anodized aluminium and steel
• Glass
• Timber
• PVC and rigid plastics

Important: While SealProof maintains excellent adhesion to most common building substrates, preliminary tests are always recommended substrates where adhesion is critical

Application

• Application temperature is between 5°C to 35°C
• SealProof can be applied by means of a hand or air operated cartridge or sausage gun
• Avoid 3 sided adhesion to movement joints by installing bond breaker tape or backer rod to joint
• For best performance, the depth of the joint should be half the width for joints greater than 10mm.
• Extrude the SealProof into the joint ensuring that no air is trapped in the joint
• Wide joints may require multiple passes of the application gun to make sure that sealant is in full contact with the sides and bottom of the joint
• Tool off sealant to ensure full contact to all sides of the joint and the entirety of the joint volume filled. Tooling will also break any air bubbles within the sealant bead and displace any air pockets within the joint
• Finally tooling of the joint surface can be done effectively with a spatula to ensure a concave finish
• When masking tape is used for maintaining neat/straight lines, ensure the tape is removed from sides of joint before the sealant starts to skin over or cures
• In conditions of low atmospheric humidity, it is advisable to spray the surface with a fine mist of water to promote early skinning once joint is finished
