Acryloid cement often has excellent ageing properties.
The acrylic pressure-sensitive adhesive of thickening can also become cloudy, and show to be present in many acrylate pressure sensitive adhesives combinations
Transparency characteristic in thing suffers damage.This muddiness shows limited between tackifying resin and acrylate copolymer or incomplete
Compatibility.Compatibility reduces causing bonding force performance with aging and decline, and shows as viscosity and declines or peel adhesion
Reduce.In some cases, to gluing containing the mixture between acrylic monomers, polymer, oligomer and its any a few persons
Tackifying resin is added to be transparent and be compatible in mixture composite.But, remove after solvent, solidify adhesive or Jing
Cross aging, adhesive can become muddy, show that there are some incompatibilities between tackifier and acrylic acid base polymer.
