SB 2460 Silane IBTM 40% VOC OTC 400 is a 40% solids solution of isobutyltrimethoxy silane that gives deep penetration into the masonry surface for a long lasting hydrophobic effect. In most cases, there is little or no color change in the appearance of the treated masonry. Unlike the common solvent carriers such as ethanol and mineral spirits used in other brands of silanes, the special carrier in SB2460 has been shown to not cause production of ground level ozone and has been granted VOC exempt status by the US EPA. Successful applications have been made on brick and concrete. SB2460 has less than 400grams per liter VOC even when calculated by the more stringent method of VOC calculation adopted by the Ozone Transport Commission (OTC) member states which exclude the volume of exempt solvents from the formula. Do not thin or dilute as this will likely violate VOC requirements. Isobutyltrimethoxysilane and 40% solutions in several solvents have shown good results in NCHRP testing. The evaporation rate is slightly faster than that of common alcohol solutions

Preparation

All surfaces, subsurfaces, and equipment must be completely dry to allow the material to penetrate before reaction with the substrate. Protect all non masonry surfaces from dripping or over spray. Provide protection for windows, foliage, adjacent surfaces that are not to receive treatment, vehicle and pedestrian traffic. Take precautions to protect other surfaces from wind drift. Using the method to be used on the project, apply an area of 10 square feet to calculate the coverage rate per gallon and to determine if there will be any unacceptable color change. For most masonry, coverage rates should be between 70 to 200 square feet per gallon. All masonry surfaces should be clean, surface and subsurface dry prior to application. A spray application is preferred but roller and brush applications can be successful as long as there is complete surface saturation. Spray equipment must be clean and equipped with solvent resistant hoses and gaskets. Apply with a coarse low pressure spray creating a saturating 6 to 10 inch run down of the fluid. On extremely porous surfaces, use the pre wet and flood coat application method. Do not apply in conditions of condensing humidity (dew) or if rain is expected within 24 hours of application or before all of the solvent has completely evaporated.

Limitations

ShoreBest 2460 is to be applied by professional applicators that use this type of material in the regular course of their business. All masonry surfaces must be free of any agent or agents that will prevent penetration of the fluid. Application should not be undertaken when rain is eminent within 24 hours or if there is frost or ice in the surface. The best results are obtained when surface and ambient temperatures are at least 40 degrees and rising. SB 2460 Silane 40% IBTM VOC OTC 400 should not be appied if temperatures are expected to be below 50 for more than one hour during the first 4 hours after application. Do not alter the product with any other material. If the fluid comes in contact with window glass or other non masonry surfaces, remove immediately with a solvent soaked rag. Do not return unused product to the original container. Close the factory container after each withdrawal. Clean all equipment with solvent after application has been completed for the day.
