AMERCOAT 242

Product catalog summary
Description: AMERCOAT® 242 is a universal glass flake epoxy coating known for its high build, abrasion and impact resistance, and excellent corrosion protection. It dries well even at low temperatures.
Principal Characteristics: The coating is gray with a low sheen. It is important to note that epoxy coatings may chalk and fade when exposed to sunlight, with light colors prone to ambering.
Basic Data: The product consists of two components with a volume solids content of 88 ± 2%. It has a VOC content of max. 1.2 lb/US gal. Recommended dry film thickness ranges from 8.0 to 20.0 mils, with a theoretical spreading rate of 71 ft²/US gal for 20.0 mils. The shelf life is at least 24 months for the base and 36 months for the hardener when stored properly.
Substrate Conditions and Temperatures: Proper surface preparation is crucial for coating performance. For steel, various SSPC standards are recommended depending on the service type. Concrete should be prepared according to SSPC SP-13, and non-ferrous metals and stainless steel should follow SSPC SP-16 guidelines. The substrate temperature during application should be between 20°F and 120°F, with ambient temperatures between 20°F and 110°F.
System Specification: Primers include DIMETCOTE-Series Primers and AMERCOAT 68HS. Topcoats include PITTHANE and AMERCOAT polyurethanes.
Instructions for Use: The mixing ratio is 80:20 by volume. The product requires an induction time based on temperature, with a pot life of 1.5 hours at 70°F. Application should be done with good ventilation and shelter from particulates.
Additional Data: Overcoating intervals and curing times vary with temperature. Safety precautions and worldwide availability are noted, with modifications possible to comply with local regulations.
Warranty and Liability: PPG provides specific warranties and disclaims others. Limitations of liability are outlined, emphasizing the user's responsibility to determine product suitability.

Notes: - Dry times are dependent on air and surface temperatures as well as film thickness, ventilation, and relative humidity. Maximum recoating time is highly dependent upon actual surface temperatures – not simply air temperatures. Surface temperatures should be monitored, especially with sun-exposed or otherwise heated surfaces. Higher surface temperatures shorten the maximum recoat window - Surface must be clean and dry....
