To eliminate the high cost associated with silicone staining in porous substrates, Pecora is introducing an exciting new line of silicone products - NST Non-Staining Technology. A true innovation in sealant technology, Pecora's NST Non-Staining Technology, including 864NST, 890NST and 895NST, is the industry's first complete line of non-staining silicones.
Architects, builders, and contractors benefit greatly from the revolutionary properties of the NST Non-Staining Technology line of products.
- Architects and specifiers can choose an NST sealant with the confidence that regardless of the substrate it will not be damaged by the silicone. And because the NST silicones are available in a variety of modulus - as well as any color you can imagine - the sealant decision process has been made even easier.
- Contractors and builders can use this revolutionary new line of products knowing that their projects will be seen in years to come for the quality of their workmanship instead of unsightly staining from the sealant. In addition, the NST silicone line provides the practical benefits of improved adhesion and reduced dirt pick-up.
Pecora's Non-Staining Technology removes the possibility of damage to a valuable substrate resulting in costly repair work and to an architect's or contractor's very reputation. "NST gives a specifier confidence," states Chris Sajbel, Pecora's new Western Regional Sales Manager. "With Pecora there is no worry that the substrate will remain its original color and free from dirt pick-up."
With traditional silicone sealants, the fluids responsible for flexibility are able to migrate away from the cured sealant to create two kinds of damage to the building substrate - staining and residue rundown.
- Staining is present when the fluid is absorbed into porous substrates such as marble, granite and limestone, causing permanent discoloration in the stone.
- Residue rundown occurs when the fluid is not absorbed into the substrate, but migrates from the sealant, runs down the face of a building, and causes a streaking effect as it collects dirt.
Pecora's NST Non-Staining Technology removes the fluid causing the damage while maintaining the flexibility necessary to accommodate a building's constant movement. "The new 895NST formula is a dramatic improvement over the original 895 product," says James Rothnie of Puget Sound Caulking in Seattle, WA. "The smoother consistency and fuller body bring it much closer to the handling and workability of the 890. The non-staining feature is a definite bonus, but its improved workability alone makes it worth the second look."
