Type / Technology




           
   Your choices are...
 
      
 
   Cement / Binder
 
     Cement refers to a mixture of binder and aggregate to form concretes or mortars such as Portland cement (calcium silicate), potassium silicate or polymer cement. Sometimes the term "cement" is used to describe mortars and other cement products.
 
   Mortar
 
     Mortars consist of a mixture of a binder or clinker and a fine aggregate. They are used to bond together brick or other components in structural applications. 
 
   Concrete
 
     Concrete consists of specialty cement or Portland cement and water mixed with coarse aggregate (e.g., gravel or crushed stone), fine aggregate or sand.
 
   Caulk / Grout / Filler
 
     Grout and caulk are types of sealants used to fill in gaps between tiles, bricks or other components.
 
   Coating / Thinset
 
     Cement based coating products are thin set materials applied in thinner layers than liner products, mortar or concretes.  The terms thinset cement, thinset mortar, dryset mortar and drybond mortar are synonymous.
 
   Pre-cast Shape
 
     Concrete or cement product in the form of a block, sheet or pre-cast shape.

   Setting / Cure Technology:       
   Your choices are...
 
      
 
   Chemical Setting
 
     Binder or adhesive set through a chemical reaction process.  Silicates (sodium, potassium, ethyl, etc.) are commonly used as binders in foundry, refractory and grinding wheel applications. 
 
   Heat Setting / Thermoset
 
     Heat setting or thermoset bond use an elevated temperature and/or pressures to set the binder.  Thermoset resins binders are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins do not melt and flow when heated, but they may soften.  Phenolic, melamine and urea formaldehyde resins are thermosetting adhesives that offer strong bonds and good resistance to high temperatures. 
 
   Two / Multiple Component
 
     Two or multi-component bond or binder systems consist of two or more resins or a resin and a hardener or catalyst that when combined react and cure into a polyermized compound or bond.
 
   Other
 
     Other specialized, proprietary or unlisted technology type.

Chemical System Type




   Bond / Binder Type:       
   Your choices are...
 
      
 
   Acrylate
 
     Acrylic binders are known for excellent environmental resistance and fast-setting time compared to other resin systems.  Polymerizing acrylic or methylacrylic acids through a reaction with a suitable catalyst makes acrylic binders. They cure through a free radical mechanism. While they are usually supplied in two-component form, they do not typically require mixing. The catalyst, accelerator or hardener can be applied to one surface and the acrylic resin to the other surface.  These adhesives or sealants are called two-step systems. Sufficient diffusion will occur when the surface are adjoined to complete curing of the adhesive.  Acrylic binders are available in both of emulsion and solvent based versions.
 
   Epoxy
 
     Epoxy resins or binders exhibit high strength and low shrinkage during cure. Epoxies are known for their toughness and resistance to chemical and environmental damage. Most epoxies are two-part systems cured at room temperature. Some thermally cured or thermoset one-part epoxies are also available. Depending on the formulation, epoxy resins are used as potting agents, resin binders or laminating resins in fiberglass or composite construction, electrical conductors in microelectronic packaging and various structural bonding applications.
 
   Furan
 
     Thermosetting resins or binders in which the furan ring is an integral part of the polymer chain. Furan resins are made by the polymerization or poly condensation of furfural, furfural alcohol, or other compounds containing a furan ring, or by the reaction of these furan compounds with other compounds (not over 50%). Fire-retardant furans are used in hand lay-up, spray-up and filament winding operations. Furans are commonly used in foundry binders, polymer concrete or mortar binders, grinding wheels, refractories and other high temperature applications.  Furan resins and chemicals are also used in fiberglass composites, hybrid resins with epoxy or phenolic, and in corrosion resistant cements.
 
   Phenolic / Formaldehyde
 
     Thermosetting resin binders based on the phenol formaldehyde or other formaldehyde system.
 
   Polyester
 
     Thermosetting resin binders based on the polyester or alkyd system.
 
   Polyurea
 
     Polyurea resins or binders are formed through the reaction of an isocyanate component with amine compounds. Polyurea resins used as a replacement for phenolics or other formaldehyde resins in particle or fiberboard binder applications. Diisocyanates react with diamines to yield polyureas. The reaction is very fast and results in a strong polymer, popular for coatings applications.
 
   Polyurethane
 
     Polyurethane resins or binders provide excellent flexibility, impact resistance and durability. They are available in one or two-part adhesive systems. Polyurethanes are formed through the reaction of an isocyanate component with polyols or other active hydroxyl group compounds. Polyurethanes bond well to plastic surfaces and make an excellent flexible potting compound. Polyurethanes require a catalyst, heat or air evaporation to initiate and complete curing.  Some disadvantages of polyurethanes are their short shelf life due to hydroscopic (water absorption) tendencies and their generally slower cure combined with more complicated handling and curing procedures.
 
   Silicone
 
     Resin binder based on silicone bond system. Silicone a produced through the hydrolysis and polymerization of silanes and siloxanes.
 
   Vinyl Ester
 
     Resin binders based on the vinyl ester system.
 
   Other
 
     Other unlisted, specialty or proprietary polymer bond or modifier system.
