RoadWeld® NOTE: RoadWeld® is currently not available for purchase. A very high solids, waterborne, pourable or extrudable, medium density, thermoset elastomer which possesses aggressive surface adhesion properties for bond resistant substrates. Available in black, and exhibiting, supple elasticity with a very low modulus at 100 percent elongation. RoadWeld is ideal for hard-to-seal joints and cracks in rigid, traffic heavy substrates such as roads and sidewalks. Available in a pourable pint container, or 5- and 54-gallon drum.
ADVANTAGES: • No-asphalt, elastomeric binder polymer, thoroughly time tested, worldwide, in harsh, weather-exposed environments for over thirty years without service interruptions. • High tack and wet out assures permanent bond to irregular, damp substrates. • Viscosity may be easily adjusted from a caulk or injection medium, to pourable quality by stirring small quantities of water into the RoadWeld. • Thermoset properties prevent hot weather creep. • Remains well bonded and supple at sub-freezing temperatures to assure year round sealing performance. • Sag resistant in larger than normal gaps. • Superior sealing with watertight bond to substrate by cured multi-polymer structure. • Persistent cure of thick cross sections improved by high solids SPICE chemistry. • Pourable but flow resistant texture provides joint depth control without using excess material. • Odorless and very low VOC minimizes user and applicator impact during installation. • Reduced product bulk density makes container shipping and handling less expensive and less labor intensive. USES: • As a waterproof caulk, sealant or filler for joints, gaps, cracks, or voids in metal, concrete, asphalt plastic or dry wood substrates. Not recommended for use as a contact adhesive. • Although the product is paintable, because of its soft, compressible properties, it is not recommended for use where traffic loadings such as hand, foot or tire contact may place a repetitive load directly against the cured cross section. TRANSPORTATION: APPLICATION: Caulk or Injection Pour Method For application in areas which require a minimum disruption of continuous traffic, a light sanding of the RoadWeld residue not scraped into the void will allow immediate tire or foot traffic. If; 1) good drying conditions exist and 2) a few minutes of traffic closure are allowed, the surface residue will dry quick enough to not cause tracking by tires, therefore the light sanding for rolling traffic should not be necessary. NOTE: RoadWeld, as a water based product, will shrink as it dries. Be prepared to place another layer on the crack as needed. DO NOT APPLY IF A THREAT OF SNOW, RAIN, HEAVY DEW OR FREEZING WOULD DISRUPT THE FULL CURE OF THIS PRODUCT. STORAGE AND HANDLING: • Keep out of reach of children. • Do not allow to freeze prior to application. • Do not thin or mix with any other products. • Avoid prolonged skin contact. • Keep containers tightly sealed when not in use. • Do not take internally. Do not induce vomiting if swallowed--call a physician immediately. • Store, handle and dispose per MSDS requirements.
