Soudal T Rex Flex Sealant Adhesive

Product Description

Soudal T Rex Flex Sealant Adhesive highly elastic sealant and adhesive for a wide range of bonding, sealing, and filling applications.
Due to its high flexibility of 750%, it will absorb the movement of the materials onto which it is applied and is suitable for sanitary areas. Once cured it forms a strong and elastic waterproof seal. It is based on the unique SMX® Hybrid Polymer technology developed by Soudal.

Nature: rigid, clean, free of dust and grease, dry or slightly moist.

Surface preparation:
Soudal T Rex Flex Sealant Adhesive has a good adhesion to most substrates. However, for optimal adhesion and in critical applications, such as joints exposed to extreme weather conditions, high- or water- loaded joints, we recommend to follow a pretreatment procedure. Prepare non-porous surfaces with a Soudal Surface Activator (see Technical Data Sheet). Porous surfaces should be primed with Soudal Primer 150.

Soudal T Rex Flex Sealant Adhesive has been tested on the following metal surfaces: steel, AlMgSi1, electrolytic galvanised steel, AlCuMg1, flame galvanised steel, AlMg3 and steel ST1403. T-Rex Flex has an excellent adhesion on most common substrates: all usual building substrates, natural stone, treated wood, PVC, plastics. T-Rex Flex also has a good adhesion on plastics: polystyrene, polycarbonate (Makrolon®), PVC, ABS, polyamide, PMMA, fiberglass reinforced epoxy, polyester.
While producing plastics very often releasing agents, processing aids and other protective agents (like
protection foil) are used. These should be removed prior to bonding or sealing.For optimum adhesion the use of Surface Activator is recommended.

NOTICE: bonding plastics like PMMA (e.g. Plexi® glass), polycarbonate (e.g. Makrolon® or Lexan®) in stress loaded applications can give rise to stress cracking and crazing in these substrates. The use of T-Rex Flex is not recommended in these applications. Not suitable for PE, PP, PTFE (eg Teflon®), bituminous substrates, copper or copper-containing materials such as bronze and brass.
We recommend a preliminary adhesion and compatibility test on every surface.

Application Method

Refer to the current Technical Data Sheet on our website prior to use.
Apply the product with high thrust-ratio caulking gun.
Smoothen the joint with a spatula with the help of finishing solution.
Avoid that soapy solution comes between the joint edges and sealant (to prevent adhesion loss).

Application method: With manual- or pneumatic caulking gun.

Cleaning: Clean with Soudal Surface Cleaner or with Soudal Swipex, immediately after use.
Cured Soudal T Rex Flex Sealant Adhesive can only be removed mechanically.

Finishing: With a soapy solution or Soudal Finishing Solution before skinning.

Repair: With the same material.

Health and Safety Recommendations

Take the usual labour hygiene into account.
Consult label and material safety data sheet for more information.
Use only in well-ventilated areas.

Remarks

• Soudal T Rex Flex Sealant Adhesive may be overpainted with water based paints, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application.
• The drying time of alkyd resin based paints may increase.
• Soudal T Rex Flex Sealant Adhesive can be applied to a wide variety of substrates. Due to the fact that specific substrates such as plastics, like polycarbonate, etc, may differ from manufacturer to manufacturer, we recommend preliminary compatibility test.
• Soudal T Rex Flex Sealant Adhesive cannot be used as a glazing sealant.
• Not suitable for bonding aquariums.
• Soudal T Rex Flex Sealant Adhesive can be used for bonding of and sealing on natural stone.
• The sanitary formula should not replace regular cleaning of the joint. Excessive contamination, deposits or soap remainings will stimulate the development of fungi.
• Do not use in applications where continuous water immersion is possible.
