Description
SOLACRIL 755 is a self cross-linking acrylic pressure sensitive adhesive with a very high total solids value. The solvents contained in the products are ethyl acetate, heptane, acetone and methyl alcohol; the product does not contain aromatic solvents.
The product has medium-high peel adhesion and tack values, a very high cohesion, an excellent thermal resistance and a good resistance to plasticizers.
Application
SOLACRIL 755 is recommended for low temperature applications (Tg is about -51°C).

Handling
SOLACRIL 755 is supplied ready for coating by rotating blade or reverse roll. Diluted, it can be applied by rotogravure or Mayer bar. A perfect drying is necessary to fully complete the cross-linking process.
SOLACRIL 755 can be formulated with tackifiers to increase adhesion on low surface tension substrates.
Packaging
The product is supplied in iron drums (180 kg); ADR compliant IBC containers (850 kg).
Storing
Store in a cool place, protected from direct sunlight and heat sources, at temperatures between +5 and +40°C. Keep material in tightly closed containers to prevent loss of solvents.
Use within 6 months from production date (unopened and in the original packaging).
