PRODUCT DESCRIPTION
PROFOAM'S RPF -1.8 is a low viscosity, two component, rigid polyurethane spray-foam system designed for insulating wall foam applications. It has a Class I ASTM E84 flame rating and is processed by most commercially available, air- less, two component, heat controlled, urethane spray equipment. This system yields excellent coverage with a very smooth surface.

| (a) There are no warranties, express or implied, including any war- ranties for merchantability or for any particular purpose.
(b) While all data presented in Sellers’ technical data sheet is based on the best information available to Seller and believed correct, such data is not to be construed as a warranty that the product will conform to such specifications. Such technical data sheets are subject to change without notice. (c) Reported laboratory test results of fire retardancy in no way relates to the actual performance under fire conditions. Since all urethane systems are organic, they will burn. |
(d) Reported laboratory test results of the color stability in no way relates to the actual performance upon exposure to light sources. Since all aromatic urethanes experience color degradation upon ultraviolet light exposure, Seller shall not be liable for any dam- ages resulting from ultraviolet light color degradation of any aromatic urethane systems manufactured or sold by Seller.
(e) The liability of the Seller shall not exceed the purchase price and the Buyer shall not be entitled to nor the Seller by liable for any consequential, incidental, indirect or special damages resulting in any manner from the furnishings of the product. |
