Report 47 Downloads 328 Views
Elvacite® 2550 Acrylic Resin Elvacite® 2550 is a solid bead methacrylate copolymer resin. It is designed to provide excellent adhesion to metal surfaces and is a resin with good flexibility and medium molecular weight. As such, it has found use in staple cement formulations. Since Elvacite® 2550 is an all methacrylate resin, resistance to ultraviolet degradation with good exterior durability is expected.

Storage & Handling Elvacite® 2550 should be stored in a cool, dry place away from heat sources. If possible, do not store at or above the glass transition temperature as resin blocking can occur. If a resin block is formed, extra time and care must be taken to break up the mass for use. Please consult the Material Safety Data Sheet for additional safety information.

Preparing Solutions Elvacite® resins dissolve at room temperature but require constant agitation to prevent solvent-swollen granules of polymer from forming agglomerates and sticking to the walls of the vessel. Important: The polymer beads should be sifted directly into the vortex of the stirred solvent to speed wetting-out and dispersion. Continuous lowshear agitation for periods of 1-12 hours, depending on the grade and concentration of resin, is recommended. After the solution appears clear in the tank, a sample should be spread out on a Leneta card or glass. After the solvent evaporates and a film forms on the card or glass, there should not be any resin seeds. If there are any seeds, the tank should be agitated further to fully dissolve the resin. Tank agitation should not be stopped (except for sampling) until the film test indicates there are no resin seeds. Any cloudiness or residue may indicate that some polymer remains undissolved. The presence of water in the system can also cause cloudiness. Solution time can be reduced by heating; most common solvents can be heated to approximately 49°C (120°F) without the need for reflux equipment. High-shear agitation also cuts dissolving time, but requires care to avoid overheating and excessive solvent loss. Technical Data Sheet
