Syntech AS 21
Thanks to its soft and thixotropic consistency, Syntech AS 21 has excellent spreadability and is easily applicable even on materials with little or no porous, making it the optimal adhesive for bonding all the elastic bands of our Elastotex line, including the band high elasticity and resistance Elastotex 250 Combi, consisting of a special elastomeric layer in Hypalon. Excellent adhesion also on PVC and plastic materials.
Fields of application
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.
Allowed supports
Concrete
Prefabricated concrete
Wood
Floor screed
Rock walls
Steel
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".
Mode of use
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.
