Cold-Applied Joint Sealants – W. R. Meadows

Cold-applied SOF-SEAL low modulus horizontal joint sealant is a premium-grade, pourable, two-part sealant composed of a special mixture of polymeric compounds that gives outstanding efficiency in each Portland cement and asphalt concrete. As soon as correctly blended and utilized, it cures within two hours to a delicate, highly versatile, rubber-like materials that’s able to maintaining a sealed joint or crack over a large temperature range. SOF-SEAL doesn’t observe within the summer season and will not turn out to be brittle at temperatures as little as -20° F (-29° C). It remains mushy, flexible, and pliable within the joint, even after repeated freeze/thaw cycles. SOF-SEAL gives excellent elongation, excessive resiliency, tenacious bonding energy, and excellent longevity. This self-leveling sealant requires no particular utility equipment and can easily be poured into cracks and joints.

There’s an outdated saying that goes “If you don’t have the time to do it right, then when will you may have the time to do it over?” This actually applies to mass-marketed “1-day polyurea-polyaspartic” flooring methods. So many coating companies are telling their prospects that these 1-day polyurea-polyaspartic methods are a magic bullet.

4.Three It ought to be realized that a sealant and sealant joint are expected to have a design life throughout which they remain practical. However, a sealant and sealant joint will even have a service life. The intent is for service life to satisfy or exceed design life. There are numerous elements that may affect service life including sort of sealant polymer, sealant formulation, compatibility with adjoining supplies, installation methods or deficiencies, sealant joint design (or lack thereof), correct maintenance (or lack thereof), and environmental publicity, among others. The designer of a joint seal ought to take the above into consideration when designing and specifying sealants for certain purposes.

– Contact: The place meals or potable water may come into contact with the coating, usually ANSI customary 61 applies with testing carried out by NSF or UL. – Odor: Chemicals associated with some coating products may taint the taste of uncovered food and beverages; and appropriate precautions, including removing of such foods, are really useful during application. – Mechanical Loading: Abrasion, put on and influence are resisted by the toughness of the coating. Coating thickness tends to assist resistance to affect. – Chemical Publicity: The character and severity of chemical exposure depends upon the chemical compounds, their concentration, the duration of the publicity, the frequency of cleansing or flushing, the service temperature of the surroundings and the temperature of the solution.

Butyl-TiteTM Wrap is an extruded comfortable, tacky butyl sealant that is bonded to a polyethylene backing and wound on a release film. The wrap is designed to supply a excessive strength water tight seal on clean, dry concrete surfaces and joints. Butyl-TiteTM Wrap meets or exceeds the necessities of ASTM C877-01 Type III and C990-o1a.
