CAFCO SprayFilm WB : CAFCO SprayFilm WB is an intumescent fireprotection coating that provides up to -hour fire-resistance ratings for interior structural steel members.. CAFCO SprayFilm WB : CAFCO SprayFilm WB is an intumescent fire protection coating that provides up to three-hour fire resistance ratings for interior structural steel members..0 DESCRIPTION CAFCO SprayFilm WB and CAFCO SprayFilm WB are spray-applied, water-based intumescent coatings that have a shelf life of 0 months when stored in unopened, sealed containers at temperatures between 0 F (0 C) and 00 F (8 C). This material has a Class A interior finish classification when tested in accordance with ASTM E 8..0 INSTALLATION. Structural Steel Surface Conditions: All structural steel to be coated with SprayFilm WB intumescent coating must be primed with a nominal -milthick (0.0 mm) layer of a phenolic modified alkyd resin primer that has been thinned with xylene at percent by weight prior to its application. All structural steel to be coated with SprayFilm WB intumescent coating must be primed with a nominally -mil-thick (0.0 mm) layer of a metal alkyd primer that has been thinned with xylene at percent by weight prior to its application. The primers must be recommended for use by Isolatek International in their published installation instructions. Primed surfaces must be free from any grease, oil, dirt, loose mill scale, rust or any other contaminant that would inhibit bonding of the SprayFilm coating to the primer.. Installation Site Conditions: SprayFilm coatings are applied when the ambient air temperature is between 0 F (0 C) and 00 F (8 C). A minimum substrate and ambient temperature of 0 F (0 C) must be maintained prior to, during and a minimum of 7 hours after application. The relative humidity of the air at the project site must not exceed 7 percent during application, and the steel surface temperature must be a minimum of F ( C) above the dew point.. Intumescent Material Application: CAFCO SprayFilm WB and CAFCO SprayFilm WB intumescent coatings must be spray-applied using a pneumatic, electric, or gas-powered airless spray pump operating with a minimum fluid pressure of,000 psi (kg/cm ). The SprayFilm coatings are permitted to be brush-applied... Thickness: Minimum average required dry-film thicknesses of the coating applied to structural steel members are listed in Tables,, and. Thicknesses must be verified using a calibrated dry film thickness gauge... Minus Thickness Tolerance: The thickness of the coating must be corrected by applying additional material at any location where the calculated average thickness of the material is less than that listed in this report, or where an individual measured thickness reading is less than 80 percent of the thickness specified in this report... Positive Thickness Tolerance: An individual measured thickness of the coating exceeding the thickness specified in this report by 0 percent or more must be recorded as the thickness specified in the design plus 0 percent. The average thickness must not exceed by more than 0 percent the maximum listed thickness in Table A for wide flange columns protected with SprayFilm WB or Tables B and C for tube and pipe columns protected with SprayFilm WB or Table for wide flange beams protected with SprayFilm WB or Table A for wide flange columns protected with SprayFilm WB or ICC-ES Evaluation Reports are not to be construed as representing aesthetics or any other attributes not specifically addressed, nor are they to be construed as an endorsement of the subject of the report or a recommendation for its use.
