| DOWSIL™ 1200 OS Primer Clear (5 L / 4.10 kg) – Clear Adhesion Promoter & Surface Primer |
| Product Description |
| DOWSIL™ 1200 OS Primer Clear is a solvent-based, transparent adhesion promoter formulated to enhance the bonding and adhesion strength of 1-part and 2-part silicone adhesives and sealants to a variety of metal, glass, ceramic, and plastic substrates. |
| Key Features |
| • Broad Substrate Compatibility: Promotes adhesion to metals, anodized aluminum, glass, ceramics, and engineering plastics • Clear Formulation: Leaves no noticeable discoloration or staining on applied surfaces • Fast Drying Time: Air-dries quickly at room temperature within 15 to 90 minutes depending on humidity • Weather & Moisture Resistance: Creates a durable bond resistant to moisture, weathering, and environmental aging • Environmentally Friendly Carrier: Formulated with an ozone-safe (OS) volatile silicone fluid carrier |
| Applications |
| • Surface pre-treatment prior to applying silicone adhesives, encapsulants, and sealants • Structural glazing, curtain wall assembly, and industrial aluminum bonding • Automotive, rail, and aerospace silicone sealing applications requiring maximum adhesion • Enhancing adhesion strength on difficult-to-bond or low surface energy materials |
| Key Advantages |
| • 5 Liter (4.10 kg) bulk container provides high-capacity efficiency for industrial assembly and site work • Prevents adhesive bond line degradation or peeling over extended service life • Simple application via wiping or brushing a thin, uniform coating • Significantly extends the durability of silicone bonds exposed to severe weather and humidity |
Application Note: Substrates must be thoroughly cleaned and dried before application. Apply a thin coat using a clean, lint-free cloth or brush and allow to dry for at least 15 to 30 minutes before applying silicone sealants or adhesives.
