Part A (base) of GUIBAO 886 is available in white, part B(curing agent) in black, black colour after mixing.
GUIBAO 886 Silicone Structural Insulating Glass Sealant is specially designed for use as secondary sealant for structural insulating glass units.
GUIBAO 886 is available in kit: part A base in 200L drums (net 190L), part B is available in 20L pails (net 19L).
GUIBAO 886 is designed to meet or even exceed the specification of Chinese national standard GB24266-2009.
STORAGE AND SHELF LIFE
GUIBAO 886 should be stored in original unopened containers. It has a shelf life of months from the date of manufacture.
GBUIBAO 886 should not be applied:
For structural glazing of glass units onto a metal frame. GUIBAO 992 two part structural silicone and GUIBAO 999 one part structural silicone are recommended for that application.
To the materials that bleed oils , plasticizers or solvents, such as impregnated wood, oil-based caulks.
To frost laden or damp surfaces.
For continuous water immersion.
When surface temperature below 4℃ or over 50℃.
HOW TO USE
Clean all joints removing all foreign matter and contaminants such as oil, grease, dust, water, frost, old sealants, surface dirt, or glazing compounds and protective coatings.
Mixing and Dispensing
To obtain the optimal performance of GUIBAO 886, it is recommended that base and curing agent thoroughly mixed using a two-part silicone dispensing machine.
GB 886 should be mixed at a ratio of 9:1～11:1 base to curing agent by volume, or 11:1～13:1 base to curing agent by weight.
Lot matching of GUIBAO 886 base to curing agent is not required. Before use, it is recommended that curing agent be stirred to ensure the homogeneity of all components.
GUIBAO 886 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged period of time.
Priming is not usually required when using GUIBAO 886.But it is essential that adhesion is tested prior to use to decide whether to use primer or not.
Masking and Tooling
Areas 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.
When not being used, it is recommended that the dispensing equipment be purged either with the base component or flush with suitable solvent.
GUIBAO 886 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 places.
