Pecora Expands NST Non-Staining Silicones Range by Adding 898NST

Published on 2012-03-21. Author : SpecialChem

Pecora's line of NST Non-Staining Silicones has been expanded to include 898NST, Non-Staining Sanitary Silicone.

To eliminate the high cost associated with silicone staining in porous substrates, Pecora introduced the industry's first complete line of non-staining architectural silicone sealants in 2007 including:

  • 864NST Low Modulus Architectural Silicone
  • 890NST Ultra-Low Modulus Architectural Silicone
  • 890FTS & 890FTS-TXTR Field Tintable Silicone (TXTR version introduced in 2010)
  • 895NST Medium Modulus Structural Silicone Glazing & Weatherproofing Silicone
  • Now, traditional Pecora 898 Sanitary Silicone has been taken to the next level with NST Non-Staining Technology®. Traditional 898 combined silicone durability with the mildew and mold resistance necessary for interior applications where a high degree of cleanliness and freedom from mold and mildew growth is required. With NST Non-Staining Technology®, 898NST not only resists the growth of unsightly and potentially dangerous molds but also eliminates the potential for staining of natural stones such as granite, marble and limestone that can occur with traditional silicone sealants.

    "We often see very expensive commercial bathrooms or other interior sanitary applications with substrates that are not suitable for traditional acetoxy silicones", says Bob Carle, Pecora Regional Sales Manager, of the possibilities of new 898NST. "The by-products of their cure acids can be corrosive to stone and tiles."

    Like Pecora's original line of NST silicones, Pecora 898NST is neutral cure and does not contain those fluid molecules that damage natural stone such as marble or granite, protecting tiles, counter-tops or other surfaces from unsightly stains. And because no fluid is present to migrate from the sealant, there is reduced dirt pick-up on joints that can promote mold and mildew growth in warm and humid environments.

    898NST's USDA acceptance and non-staining and sanitary properties make it the perfect solution in hospitals, schools, clean rooms, kitchens and bathrooms or anywhere mold and mildew are likely to grow. It is also ideal for resetting or re-grouting ceramic or natural stone tiles.

    Carle adds, "Pecora's new 898NST is compatible with marble, granite, or other porous stones because we've taken out the fluids that can migrate into those surfaces and discolor them. This new technology is a real problem solver for tile contractors and for clean room environments, as well as for any caulking applicators doing interior work and in need of a great gunning, durable, stain-free sealant."

    Pecora 898NST is available now from authorized waterproofing distributors throughout the United States and is a professional system that must be used in conformity with manufacturer's instructions.
