They're sealants, <br />usually a latex paint that coats the <br />asbestos -containing surface. Any <br />break, puncture or crack in the sealant <br />may permit the release of hazardous <br />asbestos fibers. <br />The second type, "penetrating <br />encapsulants," are usually plastic- or <br />resin -based products. In the event of a <br />fire, they may produce toxic smoke. <br />These products cannot fully <br />encapsulate! The plastic or resin sets <br />an immediate bond upon contact with <br />the asbestos -containing material so <br />that the product cannot fully penetrate <br />to the substrate to encapsulate the <br />friable asbestos material. Moreover, <br />many plastic- or resin -based <br />encapsulants provide no lasting <br />adhesion. Because they do not achieve <br />full penetration, they cannot and will <br />not provide a lasting bond with the <br />substrate. In fact, the additional weight <br />of a plastic- or resin -based <br />encapsulant which cannot penetrate to <br />the substrate actually increases the <br />risk of delamination of the <br />asbestos -containing material. The U.S. <br />Environmental Protection Agency, after <br />field testing four paint encapsulants, <br />concluded that during the application <br />of these paint products, the asbestos <br />fiber counts exceeded the OSHA <br />Permissible Exposure Limit (PEL) <br />((12f /cc) by as much as 100 times. <br />ja.1.11 <br />,, , <br />WORKING ENVIRONMENTSI <br />technology has <br />been developed that fully encapsulates <br />asbestos fibers all the way to the <br />substrate, aids in the rebonding and <br />restructuring of the existing material, <br />and reduces the hazards of <br />encapsulation that are associated with <br />latex-, plastic-, or resin -based <br />sealants. <br />BWE 3000 (pratont pawing) <br />BWE 3000 Is the state-of-the-art In <br />asbestos encapsulation technology. <br />BWE 30.00 is a ready -to -use <br />encapsulant that penetrates <br />asbestos -containing materials up to <br />three inches. It coats the asbestos <br />fibers with a durable, non-combustible <br />adhesive coating. <br />While most penetrating encapsulants <br />require high-pressure spray equipment <br />for application, BWE 3000 doesn't. And <br />while most require sizable quantities to <br />cover square footage, SWE 3000 <br />doesn't. <br />AWS. 3000 can be sprayed on all <br />asbestos -containing materials using 35 <br />to 150 psi pressure, and it will cover at <br />a rate of 25 to 50 board feet per gallon. <br />5 <br />
