Dimethyl Silicone Oil

Construction Grade Dimethyl Silicone Oil is a linear siloxane polymer characterized by high hydrophobicity, excellent weather resistance, and thermal stability. In the construction industry, it serves as a core water repellent, concrete modifier, and high-performance release agent, significantly extending the waterproofing lifespan, freeze-thaw resistance, and surface aesthetics of building materials.

Key Applications

  1. Surface Waterproofing & Water Repellent Treatment

    Penetrates the pores of concrete, natural stone, and masonry walls to form a semi-permanent, breathable waterproof barrier. While blocking liquid water infiltration, it allows internal water vapor to escape, effectively preventing efflorescence, mold, and moss growth.

  2. Concrete & Mortar Modification Additive

    Used as an admixture in concrete mixes to lower the water-cement ratio and improve workability and fluidity. Once cured, it minimizes micro-cracks inside the structure, enhancing compressive strength and durability against freeze-thaw cycles.

  3. Mold Release Agent for Precast & Cast-in-place Concrete

    Its extremely low surface tension ensures non-stick properties with rubber, plastics, metals, and concrete. Applied as a release agent for construction molds (e.g., curbstones, precast wall panels, unfired bricks), it guarantees clean surfaces, sharp textures, and zero pinholes.

  4. Additives for Coatings & Sealants

    Added to exterior architectural coatings or silicone sealants to significantly improve UV aging resistance. It prevents coating cracking or chalking while imparting excellent scrub resistance and self-cleaning properties to the surface.

Product Advantages

  1. Outstanding Weather Resistance

    Maintains stable physical properties across a wide temperature range from -50°C to +200°C, remaining highly resilient against extreme freezing conditions and intense solar exposure.

  2. Low Surface Tension

    Features exceptional spreadability and high penetrative power, ensuring rapid wetting and deep substrate penetration into various porous construction materials.

  3. Safe & Eco-friendly

    Chemically inert, non-toxic, and odorless with low VOC emissions, fully complying with green building material standards.

Packaging, Transportation, and Storage

  1. Packaging specifications: 200 kg steel drums / 1,000 kg IBC containers.

  2. Storage conditions: Store in a sealed container in a cool, dry, well-ventilated area, away from sources of ignition and strong acids and alkalis. Transport as non-hazardous goods.
