SOFTGLUE ATP is an anionic polyurethane in aqueous dispersion suitable to formulate thermally activatable adhesives to be used, for example, in the furniture, car, footwear and construction sectors.
La sua struttura polimerica lo rende particolarmente adatto ad applicazioni su substrati di PVC contenenti plastificanti.
SOFTGLUE ATP has exceptional adhesive properties on most synthetic and natural materials. Thermal stability and resistance to plasticizers, greases and oils can be increased by adding 2 – 5% by weight of a water emulsifiable polyisocyanate. The crosslinker must be added just before the application of the adhesive and mixed thoroughly; the formulation must be used quickly, before the crosslinking starts its action. For each formulation it is therefore advisable to carry out preliminary tests to evaluate the stability of the formulation over time (shelf-life).
È possibile modificare le proprietà e le caratteristiche specifiche del film adesivo aggiungendo al prodotto dispersioni di resine, emulsionanti e addensanti.
Prima dell'applicazione, soprattutto a spruzzo, il prodotto deve essere filtrato per eliminare le particelle di polimero che possono essersi formate a causa dell'essiccazione iniziale.
For bonding operations by thermal reactivation it is recommended to operate at temperatures of at least 60 – 70°C to allow the complete activation of the adhesive layer; the actual temperature for a specific application will depend on the contact time, the applied pressure and the substrates to be bonded. Preliminary tests are therefore necessary to set the processing parameters.
