PRODUCT DATA SHEET September 18, 2015 (Revision of June 28, 2015) AMERCOAT® 242 ADDITIONAL DATA Overcoating interval for DFT up to 6.0 mils (150 µm) Overcoating with... 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...
