  • Health and Safety

    SV-313 is uninflammable.

    No contact with eye or skin. Please contact doctor or poisoning preventing center in case of poisoning. 

    If contacted with skin, take off the polluted clothes and clean thoroughly for 15 minutes or longer, then go to the doctors.

     

    Pretest Process

    Siway will sample all related materials and do testings to choose the best type of sealant and best performance to prevent any potential problems. Please ask technician of Siway for more specifics.

    Working Instruction

    Surface preparation

    Clean all dust, loose particles, greasy dirt and water with gauze or other cleaning tools. Corrosion sites should be removed by metal brush and then use acetone or alcohol to clean the surface. All former sealant should be cleaned by scraping, paring, friction, jet of strong air or suitable ways.  

     

    Primers & activators

    In general, no primers and/or activators are recommended when using JS-312. In order to obtain the best adhesive performance, corresponding primer and activator should be used. When applying, uniformly disperse primer and activator, avoid primer or activator clump and uncover of base materials.

     

    Mixing

    SV-313  doesn’t need mixing and can be used directly.

     

    Spreading 

    Spread SV-313 on base materials with glue gun, suggesting thickness of sealant is no less then 1 mm, best 3~5 mm.

    Application condition

    Recommended application conditions are under temperatures of 15-35 ℃ and relative humidity of 50%-75%. If the ambient temperature is low, and the glue speed does not meet the process requirements, sealants are recommended to be heated in 50-60 ℃ oven for 30-60 minutes.

     

    Note

    Full cure (dry 7 days under 20℃) for SV-313 should be finished before applied to water immersion places. 

    The sealant surface can be painted but solvent based paints such as colorful enamel may be incompatible. If used, in site testing should be done to ensure the compatibility.

    No permission for wet spreading technology. Solvent, water, activator and/or soap solution is not suggested. 

    No permission for using in high chloride content disinfected area like swimming pool before consulting technician of Siway.

     

    Painting Property

    SV-313  can be painted with traditional methods like epoxy or acrylic coatings when cured. If high solvent content coatings like luster enamel or high oily base coatings are used, reaction will take place at the surface of sealants, which will soften the sealant surface. 

    The tensile strength of coating should close to sealant in order to achieve the best appearance and property. Painting could be processed after 24 hours if thickness of sealant is less than 3 mm or after 48 hours if thickness of sealant is more than 3 mm.
