Environmental Consideration and Substrate Temperatures Applicators must recognize and anticipate environ- mental conditions prior to application to ensure the highest quality foam and to maximize yield. Ambient air and substrate temperature, moisture, and wind velocity are all critical determinants of foam quality and selection of the appropriate reactivity formula- tion. va^iations in ambient air and substrate tempera- ture will influence the chemical reaction of the two components, directly afccting the expansion rate, amount of rise, yield, adhesion and the resultant physical properties of the foam insulation. To obtain optimum results, the 13ayseal CC system should only be spray -applied to substrates when ambient air and surface temperatures fall within the range of 30°F and 120°F. All substrates to be sprayed must be free of dirt, soil, grease, oil .ind moisture prior to application. Moisture in any form: exces- sive humidity (>85%R.H.), rain, fog, or ice will react chemically and will adversely affect system performance and corresponding physical properties. Application should not take place when the ambient temperature is within 5°F of the dew point. Primers may be necessary dependent upon conditions; consult a Bayer MaterialScience LLC technical service rep- resentative. Wind velocities in excess of 12 miles per hour may result in excessive loss of exothenn and interfere with the mixing efficiency, affecting foam surface. cure, and physical properties and Will cause over - spray. Precautions must be taken to prevent damage to adjacent areas from overspray. Storage Conditions Store at 70°F to 80OF in a dry and well ventilated area, a minimum of48 hours prior to application of material. Materials in containers should be main- tained at 650E to 85OF while in use. Conditioned trailers or tanks may be necessary. Material tempera- ture should be confined with a thermometer or an infrared gun. Do not configure equipment to recircu- late 13ayseal CC components from proportioner back into drum. Do not recirculate or mix other suppliers' "A" or "D" component into Bayseal CC X system containers. CAUTION: If components are below suggested temperatures, the increased viscosity of the com- ponents may cause pump cavitation resulting in unacceptable SPF application. If components are above suggested temperatures, there may be loss of blowing agent resulting in diminshed yield. ?age 2 of 4 — Document contains important information and must be read in its entirety.
