Gaoseil silicone sealant has good adaptability to different substrates, but different types of substrates have their own focuses. Below, Master Xiao Gao will use a table to quickly understand the adhesion of Gao Lide's main types of products (structural adhesive, weather resistant adhesive, MS adhesive, acid adhesive) to common substrates.

Building substrate type

Gaoseal

property description

Building substrate

metal material

These materials are usually dense and strong, but surface treatments such as oxide layers and coatings can affect the bonding effect

aluminum material

 

 

 

 

stainless steel

 

 

 

 

galvanized steel

 

 

 

 

Copper doors, copper pillars, copper ornaments

 

 

 

 

Other coated steel plates

 

 

 

 

porosity
non-metallic materials

These types of materials typically have characteristics such as porosity, strong water absorption, and varying surface strengths
Easy to be eroded by oil pollution precipitation

concrete

 

 

 

 

cement mortar

 

 

 

 

brick

 

 

 

 

Stone (granite, marble, quartz, artificial stone, etc.)

 

 

 

 

Gypsum products

 

 

 

 

inorganic
non-metallic materials

This type of material has a dense and smooth surface, strong chemical inertness, and sometimes difficult to bond, requiring targeted adhesives.

plate glass

 

 

 

 

laminated glass

 

 

 

 

Hollow glass structure

 

 

 

 

Ceramic/Tile

 

 

 

 

Enamel board

 

 

 

 

composite material

Composed of two or more materials, the characteristics of each layer of material need to be considered.

aluminum-plastic composite panel

 

 

 

 

aluminum panel

 

 

 

 

Stone aluminum honeycomb panel

 

 

 

 

fiberglass

 

 

 

 

calcium silicate board

 

 

 

 

Attention: Before carrying out large-scale construction, it is necessary to conduct "compatibility" and "adhesion" tests on the specific substrate and selected high-strength sealant. This can ensure long-term reliability and safety, and avoid problems such as delamination, cracking, and contamination.

√ "indicates applicable," blank "indicates not applicable.


among which
Acidic adhesives have poor adhesion to alkaline or calcium containing substrates such as ceramics and marble, and are prone to contaminating stone materials.
All adhesives may have poor adhesion to dense, smooth non-polar plastics such as PP and PE.
The white oil in ordinary silicone adhesive can seep into porous stone materials (such as marble and granite) and cause pollution. Therefore, it is recommended to choose the "stone specific" Gao Lide A360 stone specific adhesive.
Although MS adhesive is friendly to most substrates, it is generally not suitable for structural assembly of building glass curtain walls and is only suitable for joint filling and sealing.
