Compatible with the 306-23 Metering Pump (3:1 ratio for 207 or 209 Hardener) and the 306-25 Metering Pump (5:1 ratio for 205 or 206 Hardener). Our 306 Model A Dispensing Pumps consist of two separate, parallel systems, one for the resin and one for the hardener. Each has a spring-loaded poppet-type intake valve, a piston with an O-ring seal, and a spring-loaded ball check exhaust valve.

Pumps & Large Batch Mixing Methods

Thickening

Modifying with fillers and additives makes WEST SYSTEM epoxy extremely versatile for a wide variety of bonding and coating applications. Epoxy can be thickened to the ideal consistency needed for a particular job. Epoxy thickened with adhesive (high-density) fillers strengthens structural bonds, bridges gaps, and fills voids. Epoxy thickened with fairing (low-density) fillers is easily sanded and shaped after it cures.

Laminating

The term “laminating” refers to the process of bonding numbers of relatively thin layers, like plywood, veneers, fabrics or core material to create a composite. A composite may be any number of layers of the same material or combinations of different materials. Methods of epoxy application and clamping will differ depending on what you are laminating.
