  HOW TO USE GOLOHO-L213
  As it is sensitive to light, these kinds of light like sunlight, UV, artificial light must be controlled to decrease its exposure during storage and handing process.
  All surface in contact with the material should be clean and free from impurity, grease, or other contaminants prior to dispensing the material to acquire expectant results
  Application methods: artificial brush, mechanic spray, dip
  Cure: proper length wave UV light is needed to achieve constant depth of cure, and the cure time depend on the lamp intensity and distance from the source
  Some temperature sensitive substrate should be cooled before coating.
  
  SPECIAL VERSION OF GOLOHO-L213
  The product is nontoxic after curing, but avoid contact with skin. If contact the compound with eyes, rinse immediately with plenty of water
  Shelf life and storage conditions
  Shelf life: in sealed original containers 12 months at 5~25℃
  Storage: protect from UV light, protect against humidity

RTV-1 silicone rubber / RTV 1 silicone rubber are used in bonding, sealing, encapsulating photovoltaic module components including photovoltaic frame, junction box and micro-inverter, power industry including circuit boards, electronic components, light emitting diode industry including lamp beads, lamp cap and light bar, home appliance including air conditioner, fridge, washing machine, and microwave oven, induction cooker, new energy vehicle including electronic component. GOLOHO RTV-1 silicone rubbers are designed to provide long-term bonding, sealing, encapsulating and protection against moisture, environmental degradation, mechanical and thermal shock, heat dissipation and vibration where a room-temperature-curing product is preferred.
  
  When using RTV-1 silicone rubber, all surfaces must be clean and dry. Degrease and wash off any contaminants that could impair adhesion. Suitable solvents include isopropyl alcohol, acetone, or methyl ethyl ketone. Apply a bead of RTV-1 silicone rubber to one of the prepared surfaces, then quickly cover with the other substrate to be bonded. On exposure to moisture, the freshly applied material will “skin over” in about 10 to 15 minutes at room temperature and 50% relative humidity. Any tooling should be completed before this skin forms. The surface is easily tooled with spatula. GOLOHO chemical will be tack free in about 5 to 60 minutes. After skin formation, cure continues inward from the surface. In 24 hours (at room temperature and 50% relative humidity), GOLOHO RTV-1 silicone rubbers will cure to a depth of 2 to 3 mm. Very deep sections, especially when access to atmospheric moisture is restricted, will take longer to cure completely. Cure time is also extended at lower humidity levels. Before handing and packaging bonded components, users are advised to wait a sufficiently long time to ensure that the integrity of the adhesive seal is not affected. This will depend on many factors and should be determined by user for each specific application.
