PRODUCT DATA SHEET AMERCOAT® 238 DESCRIPTION Reinforced abrasion resistant epoxy PRINCIPAL CHARACTERISTICS • Outstanding impact and abrasion resistance • Qualified as a high durability deck coating • Suitable for hull exterior for ice-going ships • Low VOC, low HAPs • Good drying properties even at low temperatures COLOR AND GLOSS LEVEL • Dark Gray, Haze Gray, Oxide Red • Black • Semi-gloss Note: Epoxy coatings will chalk and fade upon exposure to sunlight, elevated temperatures, or chemical exposure. Discoloration and normal chalking does not impact performance. Light colors will darken over time. Some batch-to-batch variation in color is to be expected. Color matches are approximate. BASIC DATA AT 68°F (20°C) Data for mixed product Number of components Volume solids Recommended dry film thickness 8.0 - 12.0 mils (200 - 300 µm) depending on system Theoretical spreading rate Shelf life Base: at least 36 months when stored cool and dry Hardener: at least 36 months when stored cool and dry Notes: - See ADDITIONAL DATA – Overcoating intervals - See ADDITIONAL DATA – Curing time RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES • Coating performance is, in general, proportional to the degree of surface preparation

PRODUCT DATA SHEET AMERCOAT® 238 Steel • Remove weld spatter, protrusions, and laminations in steel. Grind welds smooth in accordance with NACE RP-0178 • Remove all surface contaminants, oil and grease in accordance with SSPC SP-1 • Abrasive blast cleaning to SSPC SP-6 standards will give optimum performance • Achieve a surface profile of 2.0 - 5.0 mils • For maintenance and repair in atmospheric service, the product can be applied over surfaces prepared in accordance with SSPC SP-11 • AMERCOAT 114 A may be used as a pit filler for severely pitted steel and surface discontinuities • Check with...

PRODUCT DATA SHEET AMERCOAT® 238 Substrate temperature and application conditions • Surface temperature during application should be between 32°F (0°C) and 140°F (60°C) • Surface temperature during application should be at least 5°F (3°C) above dew point • Ambient temperature during application and curing should be between 32°F (0°C) and 120°F (49°C) • Relative humidity during application should be between 0% and 85% SYSTEM SPECIFICATION • Primers: No primer required. Inorganic zinc primers or zinc rich epoxies may be used for severe atmospheric service. Optimum impact resistance is achieved...

PRODUCT DATA SHEET AMERCOAT® 238 Airless spray • 45:1 pump or larger • Hardened spray tips and pump internals are recommended as the reinforcement in the product is abrasive Recommended thinner THINNER 91-82 (AMERCOAT T-10) Nozzle orifice 0.025 – 0.031 in (approx. 0.64 – 0.78 mm) Nozzle pressure 17.2 - 27.6 MPa (approx. 173 - 276 bar; 2500 - 4000 p.s.i.) Brush/roller • Use a high quality natural bristle brush and/or solvent resistant, 3/8" nap roller. Ensure brush/roller is well loaded to avoid air entrainment. Multiple coats may be necessary to achieve adequate film-build • For small areas only...

PRODUCT DATA SHEET AMERCOAT® 238 ADDITIONAL DATA Overcoating interval for DFT up to 10.0 mils (250 µm) Overcoating with... epoxy coatings Notes: - Antifouling coatings should be applied when the previous coat of epoxy is tack free, but impressionable with moderate finger tip pressure - Alkyd coatings and waterborne acrylic coatings should be applied after the film is dry to handle and not greater than three times dry to handle time - Dry times are dependent on air and surface temperatures as well as film thickness, ventilation, and relative humidity. Maximum recoating time is highly dependent...

PRODUCT DATA SHEET AMERCOAT® 238 SAFETY PRECAUTIONS • For paint and recommended thinners see INFORMATION SHEETS 1430, 1431 and relevant Material Safety Data Sheets • This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapor, as well as contact between the wet paint and exposed skin or eyes WORLDWIDE AVAILABILITY It is always the aim of PPG Protective and Marine Coatings to supply the same product on a worldwide basis. However, slight modification of the product is sometimes necessary to comply with local or national rules/circumstances. Under these circumstances...
