		Important Two-Component Material Information
Polyester Resins and Gel-Coats	Spraying and Lamination Operations

Spraying materials containing polyester resin and gel-coats creates potentially harmful mist, vapors and atomized particulates. Prevent inhalation by providing sufficient ventilation and the use of respirators in the work area.

Read the material manufacturer’s warnings and mate- rial MSDSs to know specific hazards and precautions related to polyester resins and gel-coats.

To prevent contact with polyester resins and gel-coats, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons and goggles are required for everyone in the work area.

Remove all accumulations of overspray, FRP sand- ings, etc. from the building as they occur. If this waste is allowed to build up, spillage of catalyst is more likely to start a fire.

If cleaning solvents are required, read material manu- facture’s warnings and material MSDS to know spe- cific hazards and precautions. (Graco recommends that clean-up solvents be nonflammable.)

Graco recommends that you consult OSHA Sections 1910.94, 1910.106, 1910.107 and NFPA No. 33, and NFPA No. 91 for further guidance.

Important Two-Component Material Information

Material Self-ignition

Some materials may become self-igniting if applied too thickly. Read material manufacturer’s warnings and material MSDS.

Changing Materials

•When changing materials, flush the equipment mul- tiple times to ensure it is thoroughly clean.

•Always clean the fluid inlet strainers after flushing.

•Check with your material manufacturer for chemical compatibility.

Keep Resin and Catalyst Components Separate

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination of the equipment’s wetted parts, never interchange catalyst (usually MEKP) and resin (usually polyester resin or gel-coat) parts.
