SYNTECH AS 31

Thixotropic epoxy putty for structural fixes and repairs

Code: SYN.0185

Components: 2

Appearance: Liquid

The two-component structural epoxy adhesive putty is soft, thixotropic and spatulable (malleable paste), ideal for anchoring steel connectors, hermetically sealing through-holes in concrete, bonding steel plates on concrete surfaces, as an accessory product for laying road joints, for the reconstruction of wooden beam heads, repairing cracks and reconstructing missing geometries, fixing injectors, reconstructing joints in concrete flooring and fixing ELASTOTEX 250 COMBI elastic strips, including when in contact with water destined for human consumption.

Use fields

Structural reinforcements of structural elements (beams, pillars, etc.) by bonding steel sheets to the concrete. Reconstruction of joints in concrete floorings. Rigid structural bonding (beton plaque) of prefabricated elements and of articles in different building materials: concrete, steel, glass, wood, marble, tiles, stones etc. Anchoring, bonding and attachment of connectors, ties etc. Attachment of elastic straps for waterproofing joints, ELASTOTEX. Reconstruction of wooden heads, crack repair, reconstruction of missing geometries on various supports.

Preparation of supports

The application surfaces must be suitably prepared and adequately resistant: free from dust, grease, soiling, crumbling and non-adhering parts, devoid of wet surface areas. For floorings, moreover, a shot peening or preliminary milling of the surfaces of adhesion is recommended. The metal elements are to be blasted to "almost white metal".

Use method

Make sure that the environment is well ventilated and wear the personal protective equipment mentioned in the safety data sheet. Add component B to component A, taking care to remove all the material from the packaging and mixing thoroughly with a mixer at a low number of revolutions (or a suitable manual tool), until a homogeneous mixture is obtained, indicated by the uniform colour and the absence of lumps. Apply to the surfaces with the help of spatulas, trowels, etc. Complete the tasks during the useful life of the product.
Do not apply in rainy days; do not apply on moist or wet supports; do not apply on pulverised supports; use the product immediately after mixing.
