Pecora SilcoPrime: STPU-Based Primer for Exterior Grade Architectural Wall Coatings

Pecora’s SilcoPrime is an STPU (silyl-terminated polyurethane) based interlaminary primer that is specifically formulated to promote the adhesion of exterior-grade, non-silicone-based architectural wall coatings when applied over existing silicone-based wall coatings.

Silicone based architectural wall coatings may, over time, become unsightly due to atmospheric deposits of dust and dirt. Cleaning can be costly and only a temporary measure at remediation. Re-coating with high quality acrylic architectural coatings is not an option, and is typically limited to silicone-based materials as most organic coatings will not adhere to the existing silicone-based coating. The solution is the use of Pecora SilcoPrime as an interlaminary primer which will act as a permanent bridge between the existing silicone base coating and the new acrylic architectural coating.

Some advantages of the product include:

• Extensive laboratory and field testing for durability and performance
• Easy application via brush, roller, or sprayer at 3-5 wet mil thickness
• Low-temperature application down to 10° F
• Meets federal and local VOC regulations
