Applications & Uses

Applications

Typical applications include the following:

• A base polymer for chemical and moisture resistant tank linings and coatings.
• A base polymer for underwater marine coatings.
• A base polymer for water resistant roof coatings or other construction sealants.
• A non-fugitive reactive plasticizer and processing aid for high molecular weight butyl polymers.
• Polymer base for molding and tooling systems.
• Polymer base for electrical encapsulants.
• Production of pressure sensitive adhesives.

Features & Benefits

Features

DiTech Specialty Binder & Resin offers the performance benefits of butyl rubber and the processing convenience of a liquid. It makes convenient bases for sealants, coatings, and adhesives. These coatings have higher solids than those based on butyl rubber because the DiTech Specialty Binder & Resin® products are liquids. DiTech Specialty Binder & Resin® elastomer's butyl properties impart chemical resistance to a wide variety of sealants and adhesives. It is ideal for applications requiring chemical and moisture resistance. DiTech Specialty Binder & Resin® products also provide tack to pressure sensitive adhesives and improve the adhesion of butyl-based adhesives and sealants. Since they cure by the same mechanism as butyl rubber, they become part of the polymer matrix.

Storage & Handling

Storage and Handling

DiTech Specialty Binder & Resin products are high viscosity polymers. Heating the drum lowers the viscosity for easier handling. Vent the drums before heating to avoid pressure build up. DiTech Specialty Binder & Resin® liquid polymers can be compounded with virtually any type of rubber processing equipment. Processing requirements vary with the desired finished properties and with the other formulation ingredients. Store in a dry environment to prevent damage to the packaging. The liquid rubber products are stable over a wide temperature range. They are not damaged by freezing temperatures or occasional short-term exposure to temperatures of 66°C (150°F). The shelf life is a minimum of two years if stored properly in an unopened container.

Technical Details & Test Data

Viscosity

DiTech Specialty Binder & Resin is a low molecular weight grade of butyl rubber. It is a viscous liquid at typical processing temperatures. The table below indicates the viscosity (cP) when heated to typical processing temperatures.

Temperature	Viscosity (CP)
66°C/150°F	800,000
93°C/200°F	150,000
121°C/250°F	40,000
149°C/300°F	16,000

Many systems require both butyl rubber properties and much lower viscosity. The standard method is to dissolve butyl rubber in solvent. DiTech Specialty Binder & Resin® products are much more soluble than butyl rubber, so they produce adhesives, sealants, and coatings with a lower volatile content (VOC). The viscosity at 25°C of DiTech Specialty Binder & Resin in common solvents is shown below:

Solids Content	Visc in Toluene (CP)	Visc in Mineral Spirits
10%	15	25
50%	380	1,200
90%	900,000	1,500,000
