Read MoreSurface Preparation
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 1092, it is recommended that base and curing agent thoroughly mixed using an airless two-part silicone dispensing machine.
GUIBAO 1092 should be mixed at a ratio of 9:1～11:1 base to curing agent by volume or 13:1～15:1 base to curing agent by weight.
Lot matching of GB1092 base to curing agent is not required. Before use, it is recommended that curing agent be fully stirred to ensure the homogeneity of all components.
Priming
Priming is not usually required when using GUIBAO 1092.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.
Equipment Cleaning
When not being used, it is recommended that the dispensing equipment be purged either with the base component or flush with suitable solvent.
