RISUN ****0T
Chemical Composition, Low Monol silyl terminated Polyether with
trifunctional methoxy groups.
Physical form, Clear thick liquid, viscosity approx ****0 Mpa.
S.
CAS **********5.
This is a low monol STPP hybrid polymer based on polyether of
approx ****0 MW. The shore A hardness of the resin cured with DBTDL
is approx *0.
The resin is designed to be used with DIDP plasticizer and
precipitated calcium carbonate to formulate construction and other
joint sealants with shore A hardness in the range of *5 to
*5.
The trifunctional methoxy groups can be catalyzed to cross link
with various chemicals that are well known, however extra vinyl
silane needs to be added in compounding, and the use on methanol
can further retard the cross linking reaction when used in thick
walled HDPE cartridges.
The advantage of the STPP resin with very low monol polyether is
that a high level of DBTDL plasticizer can be added, and the
sealant cures with no residual surface tack.
Use epoxy silanes and secondary amino silanes for superior adhesion
as construction sealants.
Application:
The main requirements for exterior sealants are:
Low modulus even at low temperatures
Excellent UV resistance
High colour stability and no colour change
Good adhesion to porous and non-porous substrates
High tear resistance
Paint ability when needed
Resistance to cleaning procedures
Bubble free Curing
No surface tack that gathers dust and dirt
Hybrid sealants based on Risun ****0T meet the above
requirements.
Risun Polymer for Adhesive requirements
Adhesives for hard floors such as sports arenas require:
High mechanical strength and recovery
High vibration resistance
Good chemical resistance
Excellent adhesion properties
Moisture resistance
Hard sports surfaces such as these are placed on concrete slabs and
the products required are:
Moisture resistant membrane based on Risun ****0T
Adhesive layer based on Risun ****0T
Expansion joints in the wood floor based on above construction
sealant.
RISUN ****0T POLYMER ADVANTAGES:
Softest long chain polyether for lower shore A sealants with high
movement capacity to *0% ASTM standards.
Enables bubble free curing at normal temperature & humidity
levels.
Formulations have excellent adhesion to porous stone and concrete
panels.
Excellent adhesion to aluminium with no primers and a wash with
green dimethyl carbonate solvent is enough.
Risun ****0T can be used to make a crystal water clear sealant
where expensive stone is used.
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 *0 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.
