DOWSIL™ 3-1965 Conformal Coating

Basic Product Attributes

Dowsil 3-1965 is a one-part, solventless, low viscosity conformal coating designed to provide reliable protection for electronic components. It cures at room temperature and offers a soft, low-stress elastomeric finish. This product is qualified to UL V-0, Mil-I-46058C Amendment 7, and IPC-CC-830 Amendment 1 standards, ensuring its suitability for a wide range of applications.

Product Introduction

• Dowsil 3-1965 Conformal Coating is a versatile solution for protecting sensitive electronic components from environmental stressors such as moisture, dust, and chemicals. Its low viscosity allows for excellent flow and fill in narrow gaps and spaces, making it ideal for complex circuit board designs. The coating cures at room temperature with optional heat acceleration, providing flexibility in processing. It is formulated to provide good adhesion to various substrates, including those used with low-solids (no clean) and no-lead solders.

Enhanced Attributes

One of the key features of Dowsil 3-1965 is its low viscosity, which enhances its ability to flow and fill in narrow gaps and spaces, ensuring comprehensive protection for intricate components. The coating cures to a soft, low-stress elastomer, which helps to relieve stress on sensitive components and interconnections. It has a UL Flammability Classification of 94 V-0, making it suitable for applications requiring high flame resistance. The product also includes a UV indicator for easy inspection under UV light, ensuring quality control during the coating process.

Application Scenarios

Dowsil 3-1965 is widely used in the electronics industry for coating rigid and flexible circuit boards, electronic printed wiring boards (PWB), and sensitive components. It is particularly suitable for applications involving fine pitch designs and low-solids (no clean) or no-lead solder processes. The product's ability to cure at room temperature with optional heat acceleration makes it an excellent choice for high-volume manufacturing environments where efficiency is crucial.
