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.

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.
