Joint filler - TEC7

TEC7 is a universal super-strong and flexible MS Polymer that can be used as an assembly adhesive, sealing compound, or caulk on most materials such as wood, hard surfaces, metals, as well as synthetic materials, both indoors and outdoors. It can, in many cases, replace acrylic, silicone, and polyurethane sealants, butyl sealants, assembly adhesives, wood glue, bedding compounds, window putty, etc. TEC7 is ideal for sealing against radon gas and general sealing of holes, penetrations, and cracks in floors, walls, and ceilings, permanent bonding of building elements, insulation boards, moldings, ceiling panels, interiors, fittings, and equipment on cars, boats, and caravans, etc., and caulking of moldings, frames, bathroom panels, interiors, etc. It will not cause corrosion or damage to metal/aluminum, transfer color to porous surfaces (marble, slate, granite, etc.), damage the silver coating on the back of mirrors, or dissolve polystyrene. TEC7 is food-safe, meets the emission requirements of BREEAM-NOR, and contains no phthalates, isocyanates, or harmful solvents. It has a long shelf life (18 months) and can withstand freezing and thawing repeatedly in its packaging without losing its properties. TEC7 bonds strongly (26.5 kg/cm²), adheres well even on damp surfaces, cures quickly, does not shrink, and remains flexible (12.5%) throughout its lifetime. It is vibration- and sound-damping, has good resistance to chemicals, fungi, and bacteria, is highly weather- and aging-resistant, withstands UV rays, and can be painted over with most types of paint and varnish. Once cured, TEC7 can be sanded and spot-welded. TEC7 has limited adhesion to oily wood types, pressure-treated wood, PP and PE plastics, bitumen, and silicone, and for movement joints around doors and windows, a softer sealant such as XEALPRO is recommended.
