nt movement Bonds to most substrates without priming Compatible with IG sealants Enhanced adhesion to PVCvinyl glass aluminium metals powder-coated surfaces tiles fibreglass plastic ceramic and wood AAMA-Certified component for standard and impact glazing when used in designed systems. Sikasil SG-10 Areas of Application Window and door fabrication Back-bedding and cap toe and heel beads Perimeter sealing of windows doors and skylights Conventional- and impact-glazing Kitchen and bathroom counter-topssolid surfaces and sanitary seals Marine cabins Trucks trailers automobiles RVs Component assembly processes. Typical Substrates Vinyl glass aluminium powder-coated aluminium metals tile fibreglass plastic ceramic and wood. Cure Mechanism Sikasil SG-10 cures by reaction with atmospheric moisture. At low temperatures the water content of the air is lower and the curing reaction proceeds more slowly. Industry Sikasil SG-10 Curing Speed Chemical Resistance Sikasil SG-10 is resistant to UV radiation fresh-water sea-water and proprietary aqueous cleaning agents temporarily resistant to fuels mineral oils vegetable and animal fats and oils and not resistant to organic acids concentrated mineral acids caustic solutions and solvents. The above information is offered for general guidance only. Please consult Sika Canada Inc.s Technical Services for advice on specific applications. Application Limits Not intended for structural glazing Do not allow the uncured material to come in contact with solvents or curing polyurethanes during cure Lower temperature and humidity will extend Tack-Free and Cure Rates Do not apply to damp or wet surfaces Do not apply to surfaces that will be painted May be applied below freezing temperatures if substrates are completely dry frost free and clean. Contact Sika Canada Technical Services for more information Not recommended for absorptive surfaces such as natural stone particularly limestone or marble where staining may occur. Te

st before use Do not apply to substrates that bleed oil plasticizers or solvent This material is not intended for long-term immersion in water Test sensitive substrates such as mirror backings for compatibility before use Brass and copper may discolour test prior to application Allow treated wood to age for at least six months before application of the sealant. Surface Preparation All surfaces must be clean sound dry frost-free and free of any oils grease or incompatible sealers paints or coatings that may interfere with adhesion. Projectspecific substrates must be submitted for testing before being considered for use in high-demand applications. Porous substrates should be cleaned by mechanical methods to expose a sound surface free of contamination. Non-porous substrates should be cleaned using isopropyl alcohol xylene or approved clean pure undiluted industrial-grade solvent and the two-cloth cleaning method allow the solvent to evaporate before installing the sealant. Strictly follow the solvent manufacturers instructions on safe handling. Priming Sikasil SG-10 is designed to obtain adhesion without the use of a primer however certain substrates may require priming. Consequently prior testing of the sealant with and without priming is required to determine which method is appropriate. For assistance and advice regarding primer selection contact Sika Technical Services. Sikasil SG-10 Industry Application This product is suitable for bulk-dispensing straight from drums or pails by means of a pneumatic or hydraulic pump system. For recommendation on selecting and setting up a suitable pump system please contact our Technical Services. Make sure joint design is correct. Use masking tape if desired to protect adjacent areas from contamination. Do not break cartridge seal until just before use. Surfaces should be dried before the sealant is applied. Apply sealant to dry clean surfaces using an air-operated or hand-operated cartridge gun. Normally sealant skins i

n 8 minutes dries to the touch in 1 hour and bonds in 24 hours. Expansion Joints Apply the sealant using a professional caulking gun or dispensing equipment. Do not open product container until preparation work has been completed. Apply sealant using consistent positive pressure to force sealant into the joint. Adhesive Joints Apply using professional caulking gun dispensing equipment or trowel. Apply sufficient quantity of adhesive to one or both substrates to provide designed contact-area. Surfaces may be adjusted up to one hour after application without loss of adhesive strength. Tooling and Finishing In the case of expansion joints tool to a concave shape and ensure adequate pressure to achieve maximum adhesion to the joint walls. In all cases dry tooling is recommended. Tool joint if necessary in one continuous stroke immediately after sealant is applied within 5 minutes and before a skin begins to form. NOTE DO NOT use soap water oil or tooling agent Remove masking tape immediately after tooling is completed. Removal Clean all tools and equipment and remove excess sealant from substrates while the material is uncured using a commercial solvent such as isopropyl alcohol or xylene. Strictly follow the manufacturers instructions for use and warnings. Once hardened product can only be removed mechanically. Wash soiled hands and skin thoroughly in hot soapy water or use Sika Hand Cleaner towels. Do not use solvents on skin Over-Painting Sikasil SG-10 cannot be over-painted.
