Dow Corning 121 structural glazing sealant answers the challenges facade contractors and manufacturers face with the slow cure of one-part sealants, mixing of multipart sealants and limited movement capability of tapes. Dow Corning 121 is ideal for assembly, installation or repair of structurally glazed glass and other substrates.
Dow Corning 121 structural glazing sealant answers the challenges facade contractors and manufacturers face with the slow cure of one-part sealants, mixing of multipart sealants and limited movement capability of tapes. Dow Corning 121 is ideal for assembly, installation or repair of structurally glazed glass and other substrates. Featuring easy-to-use dispensing, 121 offers a unique 1-to-1 (“121”) mix ratio and is supplied in a two-part cartridge, complete with a static mixer. Suitable for either on-site or in-shop structural glazing, the sealant offers superior silicone performance that outperforms organic weatherseals and structural tapes. The sealant’s fast, 24-hour cure rate enhances productivity compared with the 14 to 21 days required for single-part sealants, and its 1:1 mix ratio eliminates the need for specialized pumps and mixing equipment. And, Dow Corning 121 structural glazing sealant is backed with an available 20-year structural adhesion limited warranty.
Weiss Chemie Plus Technik has introduced its new Big Six for sealing and assembly adhesives. This new MS-polymer product series consists of sealing and assembly adhesives that cover a wide range of applications. Designed to providing perfect adhesion to a variety of materials where reliable product performance is required, Big Six is suitable for high-performance needs. Products include multi-purpose; flexible and water resistant; slow curing (30 minutes); powerful and high tack; fast curing (five minutes) and transparent, multi-purpose options.
Quanex’s line of Q-Glaze sealants are high-performance sealants that protect the building envelope from water intrusion and moisture damage, to increase comfort, durability and longevity of the structure, matching any building professional’s needs. It features Q-Glaze Siliconized Acrylic Latex, a premium grade multipurpose siliconized acrylic latex sealant engineered to provide excellent adhesion to vinyl, aluminum, wood, sheet metal and most common building materials without the need of a primer. Also, Q-Glaze RTV Silicone, a one-component, permanently flexible, room temperature vulcanizing, mildew-resistant silicone sealant, providing excellent adhesion to cultured marble, tile, glass, vinyl, aluminum and sheet metal without the need for a primer. Next is Q-Glaze Neutral Cure Silicone, a one-component, non-sag, permanently flexible neutral cure silicone sealant, delivering excellent adhesion to vinyl, glass, aluminum, wood, sheet metal and most common building materials without the need of a primer. Q-Glaze Advanced Polymer is a multipurpose, one-component advanced polymer sealant, engineered to deliver aggressive adhesion with the most common construction substrates, while ensuring complete compatibility. Q-Glaze Advanced Polymer Plus is a high-performance, permanently flexible, easy-to-use advanced polymer sealant that allows for about 50 per cent joint movement and provides aggressive adhesion to common building substrates. Q-Glaze Advanced Polymer New Construction is a multipurpose, one-component advanced polymer sealant, engineered to deliver aggressive adhesion with the most common construction substrates, while ensuring complete compatibility. Finally, Q-Glaze Advanced Polymer Textured is a textured, high-performance, one-component, permanently flexible advanced polymer sealant that’s easy to install and ideal for a wide range of construction and industrial applications.
Safe for indoor use
Spectrem 3 is a single-component, neutral-cure, low-modulus, construction grade silicone sealant that is non-staining and has low polar attraction to dirt. Spectrem 3 has a patented chemistry that has been specifically formulated to seal porous stone, EIFS, metal panels, masonry and pre-cast concrete joints. It includes a 20-year non-stain warranty when pre-approved and tested by Tremco in accordance with ASTM C1248. Spectrem’s low polar attraction to dirt makes buildings easier to clean and maintain. The low-modulus and low Shore A hardness reduce the chances of EIFS substrate failures when compared to applications with medium-modulus sealants. The sealeant features primerless adhesion to most porous substrates with extended tooling time and workability in high temperatures. Spectrem 3’s ease of use reduces the risk of application failure. The matte finish affords an aesthetically pleasing appearance with EIFS and stone substrates. There is no cure inhibition with Spectrem 1, Spectrem 2, or Dymonic FC when applied “wet-to-wet,” minimizing the chance of leakage when sealants abut at glazing and other façade intersects. The low-VOC and zero-solvent content satisfies LEED Indoor Environmental criteria. Greenguard Gold certification ensures safety for use in the most sensitive indoor environments including hospitals and schools.
Apply below freezing
Sikasil WS-295 FPS is a neutral-cure, no-bleed, field-pigmentable silicone sealant for use in conventional glazing; perimeter sealing of windows, doors and skylights; unitized curtain wall assembly and field installation; precast expansion joints; and weather sealing of joints in most common building materials. It is a one-part sealant with a site-added colour pack. It may be applied in below-zero freezing temperatures if substrates are completely dry, frost-free and clean. WS-295 features excellent gunability in all temperatures and adhesion to porous and non-porous materials, including glass, aluminum, metal, tile, fibreglass, plastic, ceramic, masonry, concrete, brick, powder coated aluminum, fluoropolymer painted surfaces, vinyl, PVC, granite, limestone, marble and wood. It is capable of accommodating plus or minus 50 per cent joint movement. The product is non-staining, maintaining the appearance of architectural substrates and unaffected by most atmospheric conditions. It meets industry specifications ASTM C920 Type S, Grade NS, Class 50/50, NT, M, G, O; TT-S00230C, Type II, Class A; CAN/CGSB 19.13-M87; AAMA 802.3 and California Air Resources Board 2003 requirements for VOC content. Available colours are Aluminium, White, White Colonial, Bronze, Bronze Medium, Limestone and Black.
