TP POLYMER RISUN 30000T
ADVANTAGES For Risun STP polymer Resins:
Softest long chain polyether for lower shore A sealants with high movement capacity to 20% ASTM standards.
Formulations have excellent adhesion to porous stone and concrete panels.
STP POLYMER Risun 30000T can be used to make a crystal water clear sealant where expensive stone is used.
Sealant has excellent UV and chemical resistance and can be painted to match decoration changes.
Sealant formulations can use the cheaper PPC fillers now available to make thick sealant.
Sealants are solvent and isocyanate free and safer for tradesman and DIY consumers.
Sealants can be made in the factory with maximum mixer temperatures of 60 degree C and low energy use.
The trifunctional polymer is catalysed with low levels of tin containing chemical like DOTL or DBTDL.
No hazard warning labels on the sealant product when displayed in retail stores.
Sealants can be thickened with polyamide wax or cheaper urea thickeners.
Environment friendly product, Non hazardous and Non DG classification of resin
Low viscosity. Easy handing and doing for the factory worker
Low cost at similar performance levels than PU prepolymer.
