Liquid Polysulfide Polymer Products
Thiokol® LP, Liquid Polysulfide Polymers
These polymers are used for the manufacture of high performance elastomeric sealants, adhesives, coatings and rubber articles which possess excellent chemical resistance and outdoor durability.
The chemical structures of LP polysulfide polymers provide specific property benefits which enhance the performance of sealants, coatings, adhesives and rubber articles. These benefits include:
LP Liquid Polysulfide Applications
Thiokol® WTS-100, Powder Supported Polysulfide
Thiokol® WTS-100 is a liquid polysulfide polymer supported on a silica powder, specifically developed for use in the rubber industry. The powder form gives an efficient and straightforward way of incorporating polysulfide with other elastomers such as nitrile and natural rubber where it can impart increased chemical and solvent resistance and reduced fluid permeability.
Thiokol® WTS-100 is widely used in the manufacture of printing blankets and sleeves where in addition to the above properties, it can enhance ink pick up and provide desired surface resilience, toughness and finish.
ZL-2502 is a polysulfide modified liquid epoxy resin. It is used in coating and adhesive formulations that require high degrees of chemical and corrosion resistance, flexibility and adhesion. ZL-2502 is self-priming and can be used on substrates that have not had the desired level of preparation.
ZL-2502 can be considered as a pre-flexibilised epoxy resin that can be cured using conventional epoxy hardeners such as liquid amines or solid amines such as dicyandiamide. Single component, heat curing adhesives can also be formulated using ZL-2502.
The adhesive properties of ZL-2502 permit its use as an adhesion promoter in polysulfide sealants and as a binder resin in primer coats for porous substrates.
