Description

RISUN ***0E 

Triethoxy silane capped resins for high tensile and tough adhesive formulations. 

Enables bubble free curing at normal temperature & humidity levels. 

Formulations have excellent adhesion to metals with fast cure. 

Excellent adhesion to aluminium with no primers and a wash with green dimethyl carbonate solvent. 

Adhesives cure with ethanol vapour which is safer for use in confined factory applications. 

Adhesive formulations can use the cheaper PPC fillers and carbon black for high tensile strength. 

Adhesives are solvent and isocyanate free and safer for tradesman and DIY consumers. 

Adhesives can be made in the factory with maximum mixer temperatures of *0 degree C and low energy use. 

The trifunctional polymer is catalysed with more environmentally friendly tin acetoacetate catalyst. 

No hazard warning labels on the sealant product when displayed in the factory. 

Formulations can be thickened with polyamide wax or cheaper urea thickeners. 

Risun polymers are based on the new generation polyether polyols, that are the same as used for PU adhesives and capped with reactive silanes that are the same as used by some silicone sealants, and this is where the hybrid name comes from. 

The polyether chain is about twice the strength of the polysiloxane chain used in silicone adhesives and lets the adhesive have better recovery from shear movement and is also more compatible when mixed with additives that do not come out of the sealant. 

The crosslinking of the sealant to form the one part curing sealant uses the same ethoxy silane chemistry as used by silicone sealants. The adhesion is excellent and in most cases with metals like aluminium there is no need for primers. 

The other big advantage over polyurethane adhesive is that there is no solvent, there are no bubbles formed when the adhesive cures and the vapour released is the less poisonous ethanol.
