Application Advice/Typical Applications


Applications- Boilproof and dry-cleanable finishing, coating and lamination of textiles and non-wovens. - Bonding of webs, particularly for manufacturing interlinings- Non-slip paper coating.-Cohesive blend component Film properties Evaporation of the water above the minimum film-forming temperature leaves a clear, colourless film. In order to obtain complete crosslinkage, additional heat treatment is required. We recommend 5 min at 140 °C for a film on which physical or chemical tests are to be performed. The crosslinked film is very soft, extensible and slightly tacky at room temperature. It is insoluble in water and resistant to many acids and alkalis. It is virtually insoluble in organic solvents. Particularly noteworthy is its good lightfastness and resistance to weathering and ageing. Instruction for use - PLEXTOL DV 245 can be diluted with water to provide spraying and impregnating liquors of any desired concentration. - These liquors can be foamed by mixing in air. For impregnation by means of foam, we recommend the addition of Marlipal 013/109 (approx. 2 g/l) as a foaming agent and ROHAGIT SD 25 (approx. 10 g/l) as a foam stabiliser. For coatings on a foam base, we suggest ammonium stearate as a foaming agent. - PLEXTOL DV 245 can be thickened by means of thickener emulsions (e. g. ROHAGIT SD 15), thickener solutions (e. g. ROHAGIT SD 25) and cellulose or starch derivatives to provide printing, nip-padding and coating compounds. - The drying process must guarantee adequate crosslinkage of the polymer, i. e. after evaporation of the water, the material must reach a temperature between 130 and 160 °C for a short period. - The crosslinkage reaction is catalysed by acid and can be accelerated by adding phosphoric acid or p-toluene sulphonic acid (approx. 10 g/l of a 10 % solution on emulsion). - By mixing PLEXTOL DV 245 with other emulsions from the PLEXTOL range , the film properties of the foamer can be influenced within wide limits and thus adapted to the intended application.
