Tec7 SprayTec

Tec7 SprayTec (ST7-101) is the first sprayable MS hybrid polymer adhesive for bonding large surfaces. This innovative product offers a new way to bond large surfaces. This spray adhesive stands out for its distinctive properties.

Repositionable thanks to its long open time

SprayTec has a long working time of up to 60 minutes, allowing you to reposition the materials. This allows you to position the materials accurately before the adhesive cures.

Suitable for damp surfaces

One of the major advantages of this spray adhesive is its ability to bond effectively to damp surfaces. This distinguishes Tec7 SprayTec from traditional spray adhesives, which often require a dry substrate for good adhesion. This makes SprayTec particularly suitable for bonding roofing materials.

Single-sided application

Traditional contact adhesives often need to be applied to both surfaces being bonded. With SprayTec, the adhesive only needs to be applied to one surface, simplifying the bonding process and increasing efficiency. This allows you to bond a larger surface area with the same amount of product.

Environmentally friendly

SprayTec has been developed with health and environmental considerations in mind. The spray adhesive is solvent-free and contains no phthalates or isocyanates, helping to reduce volatile organic compound (VOC) emissions. This contributes to a healthier working environment and reduces exposure to certain potentially harmful substances.

Benefits of Tec7 SprayTec

• Suitable for a wide range of materials.
• Easy to use (no pressing or clamping required).
• Fast strength build-up.
• Bacteria- and mould-resistant.
• Solvent-free (100% solids).
• Long working time, allowing materials to be repositioned.
• Suitable for damp substrates.

Applications of Tec7 ST7-101 (SprayTec)

The versatility of Tec7 SprayTec makes this spray adhesive an ideal solution for a wide range of applications. SprayTec is suitable for the following applications.

Roofing

SprayTec simplifies bonding roofing materials, including insulation, EPDM and PVC roofing membranes, and roofing underlay. Thanks to its compatibility with different roofing layers, SprayTec is an ideal choice for a wide range of roofing applications.

Floor coverings

SprayTec is highly suitable for bonding various floor coverings, including laminate, vinyl, linoleum, luxury vinyl tiles (LVT), cork, parquet and carpet. Its moisture-curing properties and excellent adhesion ensure a durable bond.

General construction

You can use this spray adhesive for bonding insulation, waterproofing membranes (excluding PE), acrylic shower panels, acoustic wall panels and windproofing materials. Its high adhesion and durability make it a reliable solution in demanding construction environments.

Woodworking and laminating

Thanks to its solvent-free formulation, SprayTec is suitable for use in workshops and is ideal for bonding high-pressure laminate (HPL), veneer and sandwich panels.

Directions for use

Follow the instructions below to apply Tec7 SprayTec correctly:

Before use

• Apply the adhesive to a clean and stable substrate. The substrate may be slightly damp.
• Use Tec7 Prepare & Finish to clean and degrease the substrate and to remove uncured Tec7 polymers. For heavily soiled surfaces, use Tec7 Cleaner.      
• Always carry out a preliminary test due to the wide variety of plastics and material compositions, including materials susceptible to stress corrosion.
• Test adhesion to plastics, powder coatings, exotic woods and bituminous materials. 
• Protect adjacent materials. 

During use 

• Shake the can vigorously at least 20 times before use. Hold the can upside down while doing this. Shake regularly during use.
• Screw the can onto the Spray & PUR Gun and fully open the flow control knob. Attach the SprayTec nozzle for an even spray pattern.
• Carry out a spray test on a test surface.
• Spray from a distance of 30-50 cm.
• Apply several quick passes for an even layer thickness. Spray slowly to create a bubble effect with a thicker, less uniform layer.
• Allow the sprayed adhesive layer to flash off for a few seconds before bonding. For a thick layer with a bubble effect, allow at least one minute of flash-off time.
  Immediately after application, the materials can easily be repositioned. After 45 to 60 minutes, the initial bond strength increases significantly, making the adhesive ideal for vertical bonding. The maximum open time is approximately 75 minutes at 23 °C. Do not join the materials after skin formation has occurred.
• Join the materials to be bonded and avoid heavy loads or foot traffic during curing. After 12 to 24 hours, the adhesive is approximately 95% cured. The adhesive is fully cured after seven days.

After use 

• Remove uncured SprayTec with Prepare & Finish.
• Thin layers of cured adhesive can be removed with Tec7 Remove All. 
• Unscrew the empty SprayTec can from the gun and thoroughly clean the inside and outside of the gun with Tec7 Spray & PUR Cleaner.A partially used aerosol can can remain mounted on the gun for an extended period and reused later. Close the flow control screw and clean the outside of the gun with Tec7 Spray & PUR Cleaner.
• Due to the wide variety of paints and coatings available, preliminary testing is recommended. The use of alkyd resin-based products may interfere with the drying process of both the adhesive and the paint.
