Mastic and Intumescent Coatings, CDWZ


Guide Information for Fire-resistance Ratings

GENERAL

This category covers mastic and intumescent coatings investigated for use in fire-resistance designs as detailed in Fire-resistance Ratings - ANSI/UL 263 (BXUV). The coatings are mixed at the factory and applied directly to building structures by means of pumping equipment specifically designed for that purpose or by hand with a paint brush, roller or trowel. Extrapolation of member size and/or material thickness shown in the individual designs has not been investigated.

The influence of various environments on the fire-resistive properties of the coatings has been investigated. These tests were conducted to evaluate the influence of the environments on the intumescent properties of the coating. Coating materials covered under this category may also use a topcoat material covered under Topcoats for Use in Fire-resistive Applications (XKXC2) as shown in the individual designs.

To investigate the influences of environments, the coating material is applied to either steel plates or structural steel shapes and a selected number of samples are subjected to the environments. After the environmental exposures, samples are subjected to the fire exposure defined in ANSI/UL 263, "Fire Tests of Building Construction and Materials," and/or ANSI/UL 1709, "Rapid Rise Fire Tests of Protection Materials for Structural Steel," depending on the scope of the investigation being undertaken. The ability of the coating to retain its fire-resistive properties is determined on the basis of a comparative analysis of the fire test data obtained from fire tests on samples that were exposed and fire tests on samples that were not exposed to the simulated environments.

All coatings investigated to ANSI/UL 1709 are investigated for exposure to the following standardized environments: aging, high humidity, salt spray, carbon dioxide and sulfur dioxide air mixture, and wet-freeze-dry cycling. These coatings may be investigated to other environments and the individual certifications will include the additional environments.

The individual certifications for mastic and intumescent coatings investigated to ANSI/UL 1709 may include a list of optional environments for which the coatings have been investigated.

EXTERIOR

Coatings investigated to ANSI/UL 263 for exterior use are investigated to the following standardized environments: aging, high humidity, ultraviolet light, salt spray, carbon dioxide and sulfur dioxide air mixture, and wet-freeze-dry cycling.

INTERIOR

Coatings investigated to ANSI/UL 263 for interior use are investigated to the following standardized environments: aging, high humidity and ultraviolet light. These coatings may be investigated to other environments and the individual certifications will include the additional environments. Coating investigated to ANSI/UL 263 for interior use are certified as either Interior General Purpose or Conditioned Interior Space Purpose.

Interior General Purpose

Coatings certified for Interior General Purpose are subjected to a 180-day high-humidity exposure. For coatings certified as Interior General Purpose, protection of the coating during the application and curing, the construction and the occupancy of the building are as specified by the manufacturer but limited to interior service.

Conditioned Interior Space Purpose

Coatings certified for Conditioned Interior Space Purpose are subjected to a 250-hour (10-day) high-humidity exposure. Coatings certified for Conditioned Interior Space Purpose are limited to interior climate-controlled spaces having no exposure to condensation, and where the relative humidity and temperature are controlled according to the manufacturer's recommendations or to not more than 75%, whichever is less, during the application and curing of the coating, the construction and the occupancy of the building. Dehumidification or other environmental control equipment or protection may be required to satisfy this condition.
