Pecora 895NST Structural Non-Staining Technology (+/-50) Tubes

Pecora 895NST is a high-performing, neutral curing, medium modulus silicone sealant specifically designed for structural and non-structural glazing, with excellent aesthetic characteristics in that it will not stain sensitive porous natural stones such as granite or marble and will not contribute to residue run down on non-porous surfaces such as metal or glass curtain wall facades.

Reduction in long term dirt pick up on sealant surface is also a feature of the Pecora NST line of silicone architectural grade sealants. With a dynamic movement capability of ±50% to complement its structural strength, 895NST is equally efficient as a weatherseal in the vast majority of sealant applications other than glazing. Pecora 895 is offered as an alternative to Dow Corning's DOWSIL 795 Silicone Building Sealant.

Pecora 895NST has been specifically designed for:
• Structural glazing of glass, metal and plastic. It may also be used as a weatherseal in structural glazing applications
•Non-structural glazing applications including cap, toe and heel beads and as a weatherseal in glass to glass butt joint glazing
• Sealing expansion and control joints in precast concrete panels, metal curtain walls, and natural stone
•Perimeter sealing of doors, windows and other building components
•Adhering stiffeners to building panels
•Use in unitized curtain wall systems
•Security glazing and impact-resistant window systems
•Available in translucent, black, anodized aluminum, aluminum stone, classic bronze, tru-white and red

Features:
• Excellent unprimed adhesion to most surfaces including glass, reflective glass, anodized aluminum, plastics, wood, masonry, and fluoropolymer based paints
• Long open time for ease of application and tooling
• Extremely fast cure-through after initial set
• Compatible with most laminated glass units and acrylic and polycarbonate glazing sheets
• Easily applied (gunnable) at all working temperatures
• Will not corrode building components
• Mild odor
• Suitable for use on natural stones such as limestone, granite or marble

Limitations:
Pecora 895NST should not
be used in these applications or conditions:
• To seal exterior insulation finish systems (EIFS)
• To seal horizontal joints in decks, walks, driveways, etc. subject to abrasion
• To seal marine joints at or below the waterline
• In totally confined or air-free spaces
• In designs that require painting after application of sealant
• On surfaces with special protective coatings without prior consultation with Technical Services department
• In contact with building materials that bleed oils, plasticizers or solvents, i.e. impregnated wood, oil-based caulks, green or vulcanized rubber gaskets or tapes
• When surface temperatures during application exceed 140°F (60°C)
• To damp or frost covered surfaces.
• 895NST Translucent (Pecora color #610) is not intended for use in 4-sided structural glazing applications

Non-staining technology provides an advantage over 795.
