ADHESION

UNIWALL ACRYLIC SEALANT exhibits excellent primer less adhesion to most non-porous siliceous materials.
Users must carry out their own tests due to the great variety of substrates.

The adhesion can be improved in many cases by pretreatment of the substrate with a primer.

PROCESSING

The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material such as dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and clean, lint-free, cotton cloth. Remove residual solvent before it evaporates with a fresh clean, dry cloth. For application from cartridges cut thread open, fix nozzle on top and cut to required bead size. The sealant can be applied in beads or layers. It requires moisture in order to cure.

The curing time can take longer at lower temperatures, lower humidity or by low volume of air exchange.

RESTRICTION OF USE
  • UNIWALL ACRYLIC SEALANT is not recommended for sealing of aquarium or for long term use underwater.
  • UNIWALL ACRYLIC SEALANT is not suitable for food-grade applications where the joints are likely to come in contact with food.
  • UNIWALL ACRYLIC SEALANT is not suitable for the following plastic substrates such as Polyethylene, Polypropylene.

It is the responsibility of the user to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coatings or organic plasticizers can lead to discolouration of the sealant. Cleaning agents and gaseous emissions can damage the sealant in their function or change its appearance. UNIWALL cannot make a general statement to the compatibility of all these varying materials with the sealant. In case of doubt, the user shall conduct appropriate preliminary tests.

STORAGE
