This is our most popular sealant! CRL 33S Silicone is a high quality sealant that delivers the performance you demand at a competitive price. It is a one component, room temperature curing, acetic cure, 100% silicone elastomer that does not require the addition of activators, stabilizers, or catalysts to achieve optimum performance.
Basic Uses - CRL 33S Silicone is especially designed for joining and sealing most non-porous building materials including a variety of structural materials: glass, aluminum, stainless steel, wood, and plastics. All surfaces must be properly cleaned and the sealant tooled for good adhesion. Cat. No. S1L2100 Primer may be required for these and other substrates as well.
It has a wide operating temperature range of -80 to 400 F (-62 to 204 C), and can be applied at outdoor temperatures as low as -35 to 140 F (-37 to 60 C). 33S exhibits strong physical properties: 350 psi Tensile Strength; 120 psi Lap Shear at 1/8" (3 mm) thickness and Tear Strength of 25 ppi. It will seal curtainwall joints, steel and aluminum windows, and skylights. Indoor uses include bathtubs, showers, and sanitary installations (mildew resistant clear, white, translucent white, and tan contain a fungicide for cured beads that are mildew resistant).
Available in Custom Colors. Minimum order quantity is 30 cartridges and for any quantity ordered there is a plus or minus of approximately 10-25% that will be produced and shipped since custom colors are made by the batch. Lead time is 3 to 5 weeks.
Limitations - It is not recommended for structural glazing or insulating glass glazing, concrete and stone expansion joints, horizontal decks, patios, driveway or terrace joints where abrasion is possible. Not recommended for use on concrete, marble, limestone, lead coated, copper & brass surfaces, submerged joints (swimming pools and aquariums), plazas, decks, pavements, etc. Not suitable for painting. Check cartridge label and Specification Data Sheet for additional limitations.

NOTE:This silicone is and will remain clear if properly stored in a cool dry place and away from direct sunlight. When uncured silicone is exposed to UV radiation (sunlight) it turns pinkish until it cures, it is the exposure to UV that causes the pink hue. Once cured, 24-48 hrs., the pink hue disappears completely
Product Warning:
Not recommended for structural glazing or insulating glass glazing, concrete and stone expansion joints, horizontal decks, patios, driveway or terrace joints where abrasion is possible. Not recommended for surfaces with special protective or cosmetic coatings such as mirrors, reflective glass, polyethylene or polypropylene surfaces. Not recommended for use on concrete, marble, limestone, lead coated, copper & brass surfaces, submerged joints (swimming pools), plazas, decks, pavements, etc. Remove all old sealant before applying new. Not suitable for painting. Check cartridge label and Specification Data Sheet for additional limitations.
