PPG Apcosil 605 About

PPG APCOSIL 605 Product Description

PPG APCOSIL 605 is a two-component, solvent-based, moisture-curing inorganic zinc silicate primer specially developed to provide exceptional long-term corrosion protection for steel structures exposed to highly aggressive industrial, marine, and offshore environments. The coating offers excellent cathodic protection through its high zinc content and is widely used as a heavy-duty primer in high-performance protective coating systems. (Imimg)

The primer exhibits outstanding resistance to saline conditions, moisture, solvents, and atmospheric corrosion. It is suitable for use on abrasive blast-cleaned steel and can withstand continuous service temperatures from -90C to +400C, with protection extending up to +600C when used with an appropriate topcoat system. APCOSIL 605 is typically applied by air spray or airless spray to achieve optimum performance. (Imimg)

Superior Water Repellency and Protection

Apcosil 605 penetrates deeply into masonry and concrete, creating a highly effective barrier against water intrusion. Its silicone base repels moisture while allowing the substrate to breathe, preventing damage like efflorescence and freeze-thaw spalling. Ideal for preserving structural integrity in challenging weather conditions.


Versatile Application Across Multiple Substrates

This product is compatible with a wide range of materials such as brick, stone, plaster, and concrete. Its smooth, low-viscosity formula can be applied using a brush, spray, or dip, covering 3-6 m2 per liter. The clear, semi-gloss finish ensures no change in appearance, making it perfect for both heritage and modern structures.


Safe, Sustainable, and Easy to Use

Apcosil 605 features a non-toxic, low-VOC composition, prioritizing safety for applicators and occupants alike. It boasts quick drying (1-2 hours), is stable from -10C to 70C, and presents no fire hazard with a flash point over 70C. Store in a cool, dry place using standard HDPE drum packaging.
