aluminum composite panel cladding Joining method
(7) Sealing material
In order to ensure waterproofing of joints between panels, normally a sealing material is used.
The sealing material shall meet the performance required for the atmospheric conditions.
Table3-6 below shows general performance of sealing materials, silicone, modified silicone and polysulfide sealant are often used for outdoor installation. The compatibility tests with these sealing of the sealing materials need primer for good adhesion. In addition, some are 2-component type that consists of a base component and a curing agent. Regarding the joint design such as proper joint width and thickness, please follow the sealant manufacturer's specifications.
Note: gloss increase due to plasticizer of modified silicone and polyurethane sealant
In tooling work of modified silicone and polyurethane sealant, do not smear the protection film of Aluloyal aluminium composite panel cladding with surplus sealant. The plasticizer, an additive in these sealing materials, permeates the protective film and causes a gloss increase on the Lumiflon-based fluorocarbon coating aluminium composite panel cladding.
