Adhesive ApplicationPressure Sensitive Adhesives are great for use as an application aid in the assembly process. RubberMill maintains inventory on several popular PSA products and uses off wind laminators with heated platens to apply these to rubbers, foams sponges and other gasketing materials.

We also used other methods to apply adhesives including consolidating and belt laminating, hot melt permanent and pressure sensitive beads and sprays, and simple roll application of water-based adhesives.

 

Consolidation / Belt Laminating

Lamination & ConsolidationPressurized Flatbed Laminating technology uses zoned heating, cooling, and pressure to create unique constructions of nonwovens, films, foams and fabrics to customer requirements. High loft materials can be delicately laminated with a facing or reduced to a high density pre-preg composite. The use of adhesive webs and films offer multiple options:

  • Up to 72” wide
  • Integrated inspection system
  • Slitting and crosscutting capabilities.

 

Pressure Sensitive Adhesive Application

Pressure Sensitive Adhesive ApplicationRubberMill pressure sensitive adhesive systems are designed to meet most industrial requirements. Acrylic and rubber based Pressure Sensitive Adhesive (PSA) transfer systems can be applied to most rubber, sponge and fiber materials.

Roll goods up to 60″ wide can be laminated to one or two sides to create layered composites.

Rubber vs. Acrylic PSA

Rubber-base PSA Characteristics

  • Medium service temperature (up to 200°F)
  • Poor UV resistance
  • Good initial tack and adhesion
  • Adheres to wide variety of substrates
  • Poor resistance to plasticizers and solvents
  • Cost effective

Rubber Base Adhesive Spec Sheet

Acrylic-base PSA Characteristics

  • High service temperature (up to 300°F)
  • Excellent UV resistance
  • Poor to medium initial tack
  • Excellent resistance to plasticizers and solvents
  • Good aging performance
  • Medium cost

Important Tips for Use of Parts with PSA

Storage: Enclosed parts should be stored in a cool, dry area (64°F-76°F), and 50-70% humidity. The supplier is not responsible for the performance of parts that have been stored improperly or for parts that have been stored for longer than six (6) months.

Surface Preparation: Surface must be free from oil, grease, cutting fluids, dirt, dust and moisture. Cleaning agents should be used that do not leave a residue. Different surfaces will result in different bond strengths.

Application: Make sure that both parts are at room temperature (72°F) or above before application. Both parts should be at the same temperature. Part should be applied firmly and uniformly. Stretching the part during application will result in release from the surface.
