S-40 PRIMER (ASPHALTUM)

PRODUCT DESCRIPTION:

S-40, when installed as a system with S-41, forms an acid-, alkali-and water-resistant barrier, as well as a flexible membrane, between Summitville floor brick and concrete substrates. S-40 is a penetrating, fast-drying liquid containing asphalt and a suitable solvent. No chemical action will take place when the dry film is immersed for five days at room temperature in each of the following solutions:

1% Sulfuric Acid

5% Sodium Hydroxide

5% Potassium Hydroxide

Water saturated with H2S

USES:

The S-40/41 system is recommended for use in corrosive environments, such as concrete tank and floor construction in steel, chemical, pulp and paper, and refining industry applications. It protects concrete against highly corrosive chemical attack and isolates brick from structural movement of the concrete.
