PUR HOTMELTS.Franklin Adhesives Franklins's ReacTITE line of polyurethane polyurethane Any of a class of very versatile polymers that are made into flexible and rigid foams, fibres, elastomers (elastic polymers), surface coatings, and adhesives. reactive hotmelt adhesives bonds substrates such as vinyl, melamine melamine (mĕl`əmēn'), common name for 2,4,6-triamino-1,3,5-triazine. Melamine is a trimer (see polymer) of cyanamide, H2NC≡N, and is synthesized from calcium carbide. , polypropylene polypropylene (pŏl'ēprō`pəlēn), plastic noted for its light weight, being less dense than water; it is a polymer of propylene. It resists moisture, oils, and solvents. , polyethylene, ABS, metals, wood and foams. These adhesives are 100% solids, contain no VOCs and react with available moisture to form a tough thermosetting thermosetting, adj having the property of becoming irreversibly rigid or hardened with the application of heat. In dentistry the term is used in connection with resins. bond. The adhesives' high green strength characteristics allow immediate machining after bonding, and the cured adhesive provides resistance to heat and cold, solvents, water and creep, Franklin says. |
