How to Use
Keep the surface of substrates dry and clean, without any rust, dust or greasy dirt.
Cleaning solvents include alcohol,acetone ,etc.
Excellent adhesion to most substrates except PTFE, PE,PMMA etc.
Extrude sealant with a sealant gun on cleaned surface appropriately and evenly.
If the temperature is low, curing time will be extended.
For low surface energy material(PP), plasma treatment is required.
When the surface temperature of substrates is below 4℃ or above 50℃, it is not suitable for sealant application .
Not suitable for confined spaces or on surfaces that are continuously immersed in water, should not be used as structural glazing sealant.
Not suitable for lamps sprayed with anti-fog coating.
Guibao recommends that adhesion test be carried out prior to sealant application.
