Before use, it is recommended that curing agent be stirred to ensure the homogeneity of all components.GUANHUI 805 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged periods of time.PrimingPriming is not usually required when using GUANHUI 805. But it is essential that adhesion is tested prior to use to decide whether to use primer or not.Masking and ToolingAreas adjacent to joints may be masked to ensure a neat sealant line Do not allow mask tape to touch clean surfaces to which the silicone sealant is to adhere. Tooling should be completed in one continuous stroke after sealant application. Masking tape should be removed immediately after tooling.Equipment CleaningWhen not being used, it is recommended that the dispensing equipment be purged either with the base component or flush with suitable solvent.LimitationsGUANHUI 805 should not be applied: For structural glazing To the materials that bleed oils, plasticizers orsolvents, such as impregnated wood, oil-based caulksTo frost laden or damp surfaces For continuous water immersion When surface temperature below 4oC or over 50oCSafety InformationGUANHUI 805 is a chemical product, not edible, no implantation into body and should be kept away from children.Cured silicone rubber can be handled without any risk to health.Should uncured silicone sealant contact with eyes, rinse thoroughly with water and seek medical treatment if irritation persists.Avoid prolonged exposure of skin to uncured silicone sealant. Good ventilation is necessary for work and cure placesDisclaimerThe information presented herein is offered in good faith and is believed to be accurate.
