SHARPIE MSC1-14 Modified Silicone LM is a one-component, low modulus modified silicone sealant formulated with advanced non-bleed silicone technology. Designed to reduce dirt pickup, surface streaking, and substrate staining, it delivers premium weatherproofing performance with primerless adhesion to a wide range of substrates including aluminum, coated panels, stone, tiles, concrete, mortar, and prefabricated housing panels.

Key Features

• Low modulus & high flexibility: +100/ -50% joint movement capability with excellent elongation and recovery
• Durable weather resistance: Outstanding long-term performance against UV, rain, snow, and extreme temperatures
• Non-bleed & non-stain: Prevents substrate staining on porous surfaces like marble, limestone, granite, and concrete
• Primerless adhesion: Bonds to most common construction materials without primer
• Excellent paintability: Compatible with most paint systems for seamless finishing
• Neutral cure: Virtually odorless, non-corrosive to metals, and easy to apply over a wide temperature range
• Aesthetic finish: Matte, non-glossy cured surface minimizes dirt pickup and maintains clean façades

SHARPIE MSC1-14 is compliant with ASTM C920, JIS A 5758, and other international standards. It is recommended to conduct adhesion and stain tests on substrates prior to application for optimal performance.
