DOWSIL™ Primer-C

Overview

DOWSIL™ Primer-C and DOWSIL™ Primer-C OS is an one-part chemical treatment primer designed for painted and plastic surfaces to promote sealant adhesion development. DOWSIL™ Primer C or DOWSIL™ Primer-C OS is not recommended for EIFS as the carrier solvent (ethyl acetate or methyl acetate) dissolves the EP board beneath the EIFS basecoat. It is also not suitable for the substrates without organic coated finish such as clear glass, tinted glass, natural anodized aluminium, stainless steel or galvanized mild steel.

Features

• Accelerates adhesion build of 2 part structural sealants
• Fluoresces under a 365 nm wavelength light so that a visual check can confirm presence of primer
• Conforms to South Coast and Bay Air Quality Management District Regulations for Architectural Sealant Primers
• Low VOC at 49 g/l as a low solids sealant primer
• User friendly with low VOC
• Improves quality control processes by offering a visual confirmation of primer presence
• Quick cure time
• Non staining

Application

• Improves adhesion of silicone sealants to many substrates
• Improves sealant adhesion to plastics
