Acetic silicone |
| |
Acid cure sealant product, i.e. acetic acid is given off while it is being cured. It may be transparent or coloured. It has a fast curing rate and is used for sealing glass and carpentry. It does not seal porous surfaces such as marble. |
| |
|
|
Acrylic sealant |
| |
Product manufactured with acrylic emulsions. It is not silicone. It may be painted after curing. It is non-toxic. |
| |
|
|
Aluminium cartridges |
| |
Cartridges used for packaging polyurethane filler. They ensure that moisture does not enter the pack and keep the product in perfect condition. |
| |
|
|
Application temperature |
| |
This is the temperature of the surfaces to be sealed at the time the sealant is applied. |
| |
|
|
Application tube |
| |
Short plastic tube used to apply polyurethane foam. |
| |
|
|
Bag |
| |
Long cylindrical-shaped recipient in which the silicone is packaged. It usually contains 600-800ml. |
| |
|
|
Blister
|
| |
Cardboard medium with a transparent plastic lamina and used as a pack for tubes containing small amounts of silicone. |
| |
|
|
Content |
| |
Quantity of product in ml. (generally cartridges). |
| |
|
|
Contraction |
| |
Phenomenon that occurs in the joint and involves a reduction in its width. |
| |
|
|
Curing |
| |
The silicone drying process. |
| |
|
|
Expansion |
| |
Phenomenon that occurs in the joint and involves an increase in its width. |
| |
|
|
Expansion joints |
| |
These are located between the glass and the frame and between a facade's aluminium supports. They are characterised by high deformation levels and ample movement. |
| |
|
|
Filler joints |
| |
These are generally between the frame and the wall, and between sections. They are characterised by low deformation levels and minimal movement. |
| |
|
|
Fungicide |
| |
Compounds used to destroy or prevent the development of moulds or bacteria. |
| |
|
|
Horizontal joints |
| |
These are generally used on floors and patios |
| |
|
|
Initial joint width |
| |
The distance measured between the two media at the time of applying the sealant. |
| |
|
|
Joint
|
| |
Continuity solution between two rigid materials that are subject to movement.
|
| |
|
|
Joint bottom |
| |
Material that limits sealant depth in the joint and has the three following functions:
|
It sizes the joint to give it a proper, constant depth. |
|
It increases sealant adhesion between media and enhances water- and air-tightness. |
|
It prevents the sealant from sticking to a third surface (as the sealant should not adhere to the bottom of the joint), which would lead to breakage inside the joint. |
|
| |
|
|
Joint depth |
| |
Distance between the free side or surface and the joint bottom. |
