DOWSIL 1200 OS Primer is an ozone-safe, low VOC surface primer that improves adhesion of silicone adhesives and sealants on metals, glass, ceramics, plastics, and painted surfaces. Fast drying, easy to apply, and suitable for industrial, automotive, electronics, and construction use.
DOWSIL™ 1200 OS Primer is a special surface primer developed to improve the adhesion of silicone-based adhesives and sealants on metals, glass, ceramics, plastics, and painted surfaces. Classified as OS (Ozone Safe), it features low VOC content, providing a safer and environmentally friendly application.
Applied as a thin film, it significantly enhances silicone bonding performance and prevents long-term issues such as peeling, detachment, or reduced adhesion strength. It dries quickly and is effective even when used in very small amounts.
It is widely used across industrial manufacturing, automotive, glazing, electronic housings, white goods, and construction sectors.
