Chemical Products - V-Tech High Performance MS Polymer Sealant VT-652W

V-Tech High Performance MS Polymer Sealant VT-652W is a one component, high performance sealant based on advance MS Polymer Technology. It is Solvent, Silicone and Isocyanates Free. It has an excellent UV, weather and temperature resistance. It has excellent adhesion over a wide variety of substrates and is paintable with most common industrial paints.

VT-652W High Performance MS Sealant is formulated to provide extreme tensile strength. It is recommended for bonding applications subjected to high loads or dynamic vibrations. Its applications include coast or train body bonding.

• High Strength Structural Glazing
• Good UV Resistant
• Primerless Bonding To Most Substrates
• Paintable & Environmental Friendly
• Low VOC

Applications:
It is specially formulated for structural joint that will be subjected to dynamic stresses. It is used for making permanent high strength elastic adhesive seals in marine, automotive and industrial applications. Ideal for bonding of plastics (nylon, PVC, ABS etc.), metal (stainless steel, aluminium, steel, copper etc.), rubber (natural rubber, synthetic rubber, silicone rubber, EPDM etc.), natural materials (wood, polywood, leather, cloths, paperboard etc.) & inorganics (concrete, mortar, natural stone, tile, glass, porcelain etc.)

How to use silicone sealant?

PREPARATION

Surface preparation
• Make sure that the surface you are going to silicone is clean, dry and well prepared. This is essential to achieving good adhesion and a smooth bead.
• Using a utility knife, remove any remnants of old silicone as new silicone will not adhere to it. After you have removed most of the old silicone with a blade (being careful not to scratch the surface), clean any remaining residue with a fine sandpaper or rub with alcohol.
• If the surface is mildewed, use a concentrated mildew killer after removing the old silicone. Allow to fully dry before applying new silicone.

APPLICATION

Step 1
• Make sure that the area you want to silicone is clean and dry. If filling between glass and aluminium, or whenever a smooth straight edge is required, use masking tape and mask off.
• Take the tube of silicone and, using a utility knife (held at a 45 degree angle), cut the end from the tapered nozzle. The further away from the end of the nozzle you cut, the bigger the bead of silicone that will be available.

Step 2
Pull the handle of the caulking gun all the way back and put the tube of silicone in the gun. Turn the handle down and push the handle until it stops against the end of the tube.

Step 3
• The recommended way to silicone is to “push” the bead of silicone ahead of the nozzle. This prevents air bubbles forming under the sealant.
• Use constant pressure on the trigger to ensure an even flow of the silicone.
• Seal the entire length.
• When you are done, make sure that you turn the handle up so that the pressure on the tube is released.

Step 4
• Ensure that the silicone bead is unbroken. If it isn’t, smooth with the filling knife dipped in a water and detergent solution. Remember to remove the masking tape before the silicone starts to cure.
