The Main Agent

Dec 14, 2016

Main agent is the main component of adhesive, leading adhesive adhesive performance, but also an important indicator of the difference between adhesive type. The main agent generally consists of one or two, or even three high polymer composition, requires a good adhesion and wettability. Can be used as a sticky material are:

1. Natural macromolecules such as starch, cellulose, tannin, gum arabic and sodium alginate, as well as animal glue such as bone glue, fish glue, blood protein glue, casein and shellac.

2. Synthetic resin, thermosetting resin and thermoplastic resin into two categories. Thermosetting resins such as epoxy, phenolic, unsaturated polyesters, polyurethanes, silicones, polyimides, bismaleimides, allyl resins, furan resins, amino resins, alkyd resins, etc .; thermoplastic resins such as polyethylene , Polypropylene, polyvinyl chloride, polystyrene, acrylic resin, nylon, polycarbonate, polyoxymethylene, thermoplastic polyester, polyphenylene oxide, fluororesin, polyphenylene sulfide, polysulfone, polyketone, , Liquid crystal polymers and the like, and modified resins or polymer alloys thereof. Is the largest amount of a sticky material.

3. Rubber and Elastomers. Rubber mainly chloroprene rubber, butyl nitrile ethylene-propylene rubber, fluorine rubber, polyisobutylene, polysulfide rubber, natural rubber, chlorosulfonated polyethylene rubber; elastomer is mainly thermoplastic elastomer and polyurethane elastomer.

4. In addition, inorganic binders such as silicates, phosphates and phosphoric acid-copper oxides.
