DC360 Fire Retardant Coating.
DC360 is an intumescent water based latex coating intended for application on wood-based products used in interior conditioned spaces to provide increased resistance to flammability and smoke development.
Product is marked with labels or stamp supplied by IFTI to each container. The markings include:
• Manufacturer’s name, trademark, or other recognized symbol of identification
• Product model designation
• QAI File Number B1117
• Date of manufacture or date code on the label or stamp
• Flame Spread Index / Smoke Developed Index Rating
• QAI logo shown here:
The following outlines DC360 coating ratings determined in accordance with ASTM E84:
SUBSTRATE FLAME SPREAD INDEX (FSI) SMOKE DEVELOPED INDEX (SDI) APPLICATION (WET MILS) Oriented Strand Board (OSB) ≤25 ≤50 10 Pine Boards ≤25 ≤50 10
Note: UL 723 and NFPA No 255 are equivalent and have the same ratings.
The following outlines DC360 coating ratings determined in accordance with ASTM E84 extended 20 Minutes (ASTM E2768):
SUBSTRATE FLAME SPREAD INDEX (FSI) SMOKE DEVELOPED INDEX (SDI) FLAME FRONT* APPLICATION (WET MILS) OSB ≤ 25 ≤ 50 ≤ 5 ft 10 Pine ≤ 25 ≤450 ≤ 5.5 ft 14
The following outlines DC360 coating ratings determined in accordance with CAN/ULC S102:
SUBSTRATE FLAME SPREAD INDEX (FSI) SMOKE DEVELOPED INDEX (SDI) APPLICATION (WET MILS) Pine Boards ≤25 ≤100 6
The following outlines DC360 coating ratings determined in accordance with CAN/ULC S126
SUBSTRATE DC 360 APPLICATION (WET MILS) APPROVED BUILT UP ROOF ASSEMBLIES1 Oriented Strand Board (OSB) or Plywood.
Minimum 13 mm (1/2 inch) thickness.
Minimum 0.254 mm (10 mils) DC 360 is approved for use with any built-up roof system installed between structural member locations without limitation.
Note 1: Installation limitations for CAN/ULC S126 requires the substrates noted installed with parallel to truss joints along truss member locations for mechanical fastening. Perpendicular to truss joints do not require blocking. Substrate is to be inspected to ensure substrate is clean, dry and in good condition prior to DC 360 application. DC 360 to be applied at minimum 0.254 mm (10 mils) wet film thickness, at temperatures from 10C – 30C for substrate bond. Application is to cover wood sheathing joints with DC360 to create continuous coating surface.
In field application, to installed wood framing and sheathing materials to reduce the Flammability and Smoke Development of various substrates. DC360 is designed for interior condition spaces. All surface preparation should be carried out in accordance with good painting practices. To only be applied and used in weather protected locations where substrate moisture content is below 18%. DC360 comes as a ready to use coating and must be thoroughly mixed before use. It can be applied with brush, roller or airless Sprayer. The mil thickness should to be checked during installation to ensure the minimum noted thickness are maintained.
