Soudaseal High Tack - Hybrid Polymer Sealant & Adhesive

Substrate Suitability:

Soudaseal High Tack is suitable for bonding and sealing on a wide range of building substrates, including treated wood, PVC, and various plastics.

The substrates should be rigid, clean, dry, and free from dust and grease to ensure optimal adhesion. 

For porous surfaces in water-loaded applications, priming with Soudal Primer 150 is recommended. Non-porous surfaces should be prepared using Soudal Surface Activator or Soudal Cleaner & Degreaser.

Soudaseal High Tack demonstrates excellent adhesion on most substrates. Preliminary adhesion testing on all surfaces is recommended to confirm compatibility.

Surface Preparation:

Proper surface preparation is crucial for achieving a strong and durable bond with Soudaseal High Tack. Ensure that all surfaces are clean, dry, and free from dust and grease.

For porous surfaces, apply Soudal Primer 150 to enhance adhesion. Non-porous surfaces should be cleaned using Soudal Surface Activator or Soudal Cleaner & Degreaser. 

Plastics often have releasing agents, processing aids, or protective agents that must be removed prior to bonding. For optimal adhesion, use Soudal Surface Activator.

Note that bonding plastics like PMMA (Plexi® glass) and polycarbonate (Makrolon® or Lexan®) in stress-loaded applications can cause stress cracking and crazing. Therefore, Soudaseal High Tack is not recommended for these applications.

Application Method as an Adhesive:

To apply Soudaseal High Tack as an adhesive:

1. Ensure the surfaces are properly prepared as described above.
   
   

2.  Cut the nozzle of the cartridge at a 45-degree angle to the desired bead size.
   
   

3. Insert the cartridge into an applicator gun.
   
   

4. Apply the adhesive evenly onto one of the surfaces in continuous beads or dabs, spaced approximately every 15 cm. Ensure adhesive is applied to the edges and corners of panels for a secure bond.
   
   

5. Press the surfaces together firmly and use a rubber hammer to ensure proper contact and adhesion.
   
   

6. If necessary, support the bonded materials until the adhesive cures. Allow the adhesive to cure according to the manufacturer’s instructions before subjecting it to any stress or moisture.

Application Method as a Sealant:

When using Soudaseal High Tack as a sealant:

1. Ensure the joint surfaces are clean, dry, and free from dust and grease.
   
   

2. Cut the nozzle of the cartridge at a 45-degree angle to match the width of the joint.
   
   

3. Insert the cartridge into a caulking gun.
   
   

4. Apply the sealant in a continuous, even motion, ensuring full coverage of the intended area.
   
   

5. Tool the sealant immediately after application using a suitable tool or a soapy solution to achieve a smooth finish. Perform this step before the sealant begins to skin over.
   
   

6. Minimum depth for joints is 5 mm. For optimal sealing, the joint width should be twice the joint depth.

Finishing:

After applying the sealant or adhesive, ensure the surface is smooth and any excess material is removed. Use a soapy solution before the sealant skins over to achieve a neat finish.

Soudaseal High Tack can be overpainted with water-based paints, but a compatibility test is recommended due to the variety of paints available.

Alkyd resin-based paints may have an increased drying time when applied over the sealant.

Cleaning:

For easy cleanup, use Soudal Swipex Cleaning Wipes to remove any uncured sealant residue immediately after use.

If the sealant has already cured, mechanical removal with the aid of Soudal Sealant Remover Spray is necessary. Follow the instructions provided with the cleaning products for effective removal.

Other Information:

Soudaseal High Tack is not suitable for use as a glazing sealant, for bonding aquariums, or in applications involving continuous water immersion. It may discolour under extreme conditions or prolonged UV exposure, but this does not affect its technical properties.

Avoid contact with bitumen, tar, or other plasticiser-releasing materials such as EPDM, neoprene, and butyl to prevent discolouration and loss of adhesion.

When using different reactive joint sealants, ensure the first sealant is completely cured before applying the next one.

Soudaseal High Tack conforms to LEED requirements for low-emitting materials and complies with SCAQMD rule 1168 and USGBC LEED 2009 Credit 4.1 regarding VOC content.
