Epoxidized PolysulfideAliphatic PolymerHMWSpecial for sealant
Special for sealant
Polysulfide-based materials are known for their special strength and relaxation properties. Cured polysulfide has low gas, vapor, di�usion rates, high chemical resistance (especially against fuel and solvents) and good weathering stability.
Thiopox S is an epoxidized polysulfide polymer combine the unique properties of polysulfide (softness) with those of epoxies (hardness), it uses in di�erent objects such as producing, gum and elastic sealant, flexible anti-corrosion coatings, relieving cracks of broken concretes in building, sewage pipes and surface of streets, producing marine color and two-walled glass.
Sealants based on epoxidized polysulfide Thiopox S originally found wide acceptance for applications requiring a flexible, adhering, chemically resistant composition of matter. Since they were the first liquid polymers available that could be cured at room temperature, they were soon specified for a number of military applications. Their use as a major outlet. Other military applications included a quick hose repair compound, a sealant for bolted steel tanks for quick assembly on the battle front, electrical potting compounds, caulks for wooden flight decks which were designed as a stop gap in the early days of aircraft carriers, sealing and adhering methacrylate bubbles on aircraft, sealing cocoons in the mothball fleets, adhering aluminum strips on wings for reducing air turbulence during flight and many others.
One continuing large application for epoxidized polysulfide sealants is as a glass adhesive for making insulating glass units.
Thiopox S resin provide both the strength and elasticity required.

Properties
Benefits
Highly resilient with excellent recovery characteristics
Provides permanent and uniform watertight seal
Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes
Stays flexible and won’t become brittle or crack due to ultraviolet exposure
Resists abrasion, weathering and moisture, elevated temperatures will not cause discoloration
Retains joint soundness in service once it’s cured andcan tolerate stretched or impact force
Resists mild acids, alkalis and petroleum products
Resists e�ects of sunlight, rain, snow, ozone, aging, shrinkage and cyclic temperature changes even after years of service
Contains no volatile solvents – VOC free
Self – leveling for ease of application
Excellent at maintaining gas integrity. In fact, it is three times better at retaining gas than silicone resins.

Thiopox S resin can be cured using aliphatic, cycloaliphatic and aromatic amines, phenalkamine adduct and mannich based type hardeners.
Also, accelerator curing agents can be used for speed curing time.
Curing systems for Thiopox S
Thiopox S is manufactured by reacting between two moles of an epoxy resin and with one mole of liquid polysulfide:
The reaction is catalyzed by an organic base that is usually with an amine

Application fields for Thiopox S
ECOFRIENDLY
Epobrid Thiopox S has been designed based on hybrid technology, that means this product combines advantages and abilities of epoxy and polysulfide together.
Polysulfide-based materials are known for their special elasticity, strength and relaxation properties.
Thiopox S is an epoxidized polysulfide-based resin to formulate high performance sealants that is curable amine curing agents. So, there is no any gas, vapor, di�usion rates, VOC, isocyanate and solvent.
Epobrid Thiopox S is totally non-toxic and can eliminate usage of isocyanates, silicon resins and other toxic polymeric materials from sealant industry which caused skin and breath problems and asthma for workers and users.
Beside of special abilities of epoxidized polysulfide-based sealants (excellent chemical and weathering resistance), Thiopox S attracted many industries to use from that to make safer world for humans and environment.
