Ukungalungi: Uneminyaka yobudala phantsi kokukhanya kwe-ultraviolet.
Uhlobo lweVinyl acetate-ethylene copolymer (VAE):
Iimpawu: I-copolymer ye-vinyl acetate kunye ne-ethylene, kunye nokuguquguquka okugqwesileyo kunye nokuchasana kwamanzi.
Isicelo: Ifanelekile i-adhesives ye-tile, iinkqubo zangaphandle ze-insulation wall, i-gypsum-based self-leveling, njl.
Izinto eziluncedo: Ibonelela ngokubambelela kakuhle kunye nokumelana namanzi, kwaye inokumelana okuthile kweekhemikhali.
Iingxaki: Iindleko ziphezulu ngokwentelekiso.
Uhlobo lwe-Acrylic copolymer (Acrylic):
Iimpawu: Inxalenye ephambili yi-acrylic ester, ene-adhesion egqwesileyo kunye nokuguquguquka.
Isicelo: Isetyenziswe ngokubanzi kwi-decorative mortar, i-adhesives tile, i-gypsum kunye nezinye izinto.
Izinto eziluncedo: Ukuncamathela okugqwesileyo kunye nokuguquguquka, kunye nokuxhathisa okugqwesileyo kwe-UV.
Ukungalungi: Ngenxa yexabiso eliphezulu lezinto ze-acrylic, iindleko zolu hlobo lwe-RDP nazo ziphezulu.
Imisebenzi kunye nokusetyenziswa kweRDP
Ukusebenza okuphuculweyo kokudibanisa:
I-RDP idlala indima yokudibanisa kwizinto eziphathekayo, iphakamisa ukunamathela kwe-adhesive, kwaye iphucula ukudibanisa phakathi kwezinto zokwakha kunye ne-substrate.
Iindawo zesicelo ziquka i-adhesives tile, i-bonding mortars, njl.
Ukuguquguquka okuphuculweyo kunye nokuchasana nokuqhekeka: Ngokongeza i-RDP, ukuguquguquka kwezinto eziphathekayo kuphuculwe kakhulu, okunceda ukukhusela ukwenzeka kweentanda.
Ngokuqhelekileyo isetyenziswa kwiinkqubo zokugquma, i-putty eguquguqukayo, izinto zokulungisa, njl.
Ukuphuculwa kokumelana namanzi kunye nokunganyangeki kwamanzi:
I-RDP iphucula ukuxhathisa kwamanzi kwizinto eziphathekayo, ukuvumela ukuba kugcinwe ukusebenza okuzinzileyo kwindawo enomswakama.
Ifakwe kwiingubo zokungangeni manzi, iingubo zangaphandle zodonga, njl.
