MULTIBOND-23 - Water-based pressure-sensitive adhesive

MULTIBOND-23 is a solvent free and permanently tacky adhesive. It is an aqueous dispersion of acrylic copolymers, anionic. It is characterized by high internal strength (cohesion) and high adhesion to bonded surfaces. After water evaporation the adhesive film becomes transparent and is resistant to aging.

TYPICAL APLICATIONS:

MULTIBOND-23 is mainly used to cover paper, foil, textiles and plastics (such as soft and hard PVC, polyester, polyethylene) with pressure-sensitive, tacky surface. As there is plenty of different materials available on the market is it recommended to perform control tests before accepting this adhesive for production.

Popular applications of MULTIBOND-23 include (but are not limited to) bonding foil to chipboards or fibreglass enforced plastics to hard polyurethane foam. MULTIBOND-23 is also ideal for bonding of styrofoam boards.

APPLICATION GUIDELINES:

Initial information:

Prior to using the adhesive it is necessary to get acquainted with all the safety information and guidelines comprised in the material safety data sheet (MSDS). General safety precautions are also valid even for product which are not classified as hazardous according to current safety regulations.

Surface preparation:

Bonded surfaces must be dry, free from dust, grease and oil.

Bonding:

MULTIBOND-23 can be applied using spray guns, brushes or rollers – in some cases diluting is necessary. The product has a high solids content and dries very quickly - in automated application constant adhesive flow is needed to avoid clogging the nozzle. Typical usage is not less than 20g/m² but in case of rough or absorbing surfaces this value may increase drastically.

Cleaning:

Uncured product may be removed – also from the tools and other equipment – with the use of warm water. When cured remove the adhesive with ethyl acetate.
