Rv Roof Sealant -Semi Self Leveling-White Sikaflex-715 is a camper roof sealant that has one-component silane terminated polymer (STP) sealant with
excellent adhesion and UV resistance. Apply on all seams and joints. Results in a long-lasting, durable, crack resistant seal. Very low shrinkage because it contains 98% less volatile organic compounds (VOCs) than other traditional RV roof sealants.Key Benefits of Sikaflex®-715Sikaflex®-715 = Cross-Linking DurabilityBorne in the Sikaflex® tradition, Sikaflex®-715 camper sealant is moisture cured, flexible, elastic, and durable. Traditional camper roof sealants are non-curing, drying, elastomer products. In essence these products never cure; rather they are more like putty. Sikaflex®-715 cures and this imparts a highly elastic internal strength to the product.Sikaflex®-715 Rv Roof Sealant provides a durable sealant!Sikaflex®-715 = Crack ResistantImagine a RV roof sealant that won€™t crack and the peace of mind that your RVs won€™t leak. Traditional roof sealants have large shrinkage characteristics, quickly dry and crack when exposed to the environment. Cracking RV roof sealant which causes leaks has been a persistent problem in the RV Industry. Sikaflex®-715 RV sealant is UV stable and stands up to the harshest environmental conditions. From extreme cold to hot and humid the product remains stable and the RV sealed. When a sealant cracks it creates a path for water to enter the RV. Left undetected it spells disaster for the owner and costly repairs for the manufacturer. In many cases mold has grown in the structure of RVs and caused extensive damage to the RV and personal property. *Traditional camper roof sealant has stringy, putty like substance and easilypulls apart and breaks.*Sikaflex®-715 is a €œcured€ RV sealant and demonstrates goodflexibility and retains its shape.Sikaflex®-715 = Semi Self-LevelingThe typical RV has a variety of roof penetrations around screws, skylights,vents and antennas. These items have a wide range of profiles that must besealed completely to prevent water intrusion. With Sikaflex®-715 the sealantis semi self-leveling which means the product stays where it has beendispensed. The product flows just enough to conform to the profile of theitems but will not flow away from the profile. The viscosity of the productcovers fasteners such as screws not allowing the fasteners head to beexposed. Sikaflex®-715 conforms to trim profiles, bridges gaps and fillslow spots. *Sikaflex®-715 exhibits excellent semi self-leveling & flow characteristics.Sikaflex-715 is a suitable RV roof sealant excellent for sealing a wide variety of RV roofing
components including, EPDM; metals such as anodized and bare aluminum;
phosphated, chromated and zinc plated steel; metal primers; 2-part coatings;
ceramics and plastics.
Characteristics and Advantages

Primerless adhesion to difficult substrates
Isocyanate free
Low VOC content
Excellent UV resistance Installation: Sikaflex® €“ 715 is a semi self-leveling RV sealant so the goal is to apply a large beadat the seam or profile to be sealed, and let the sealant flow uniformly in both directions. Begin by cutting about 1 inch off the end of the cartridge nozzle. Apply sealant slowly so that the finished bead width is about 1 inch wide over the seam or profile. Screws should be covered with a dollop of sealant. Clean uncured sealant with mineral spirits or other solvent-based cleaners.Post Sikaflex® €“ 715 Application InformationSikaflex® €“ 715 will skin over in about 45 minutes and the curing process beginsimmediately. Full curing requires 2 to 5 days depending on climate conditions andsealant thickness. The RV can be moved, transported, or driven outdoors, even inrainy conditions, after the skin forms on the sealant.Technical Product Data (typical values)
