STATIC METHOD FOR DETERMINATION OF VOLATILE EMISSIONS FROM
POLYESTER AND VINYL ESTER RESINS

1. PURPOSE 1.1 This test is designed for the determination of volatile organic compound emissions of polyester and vinyl ester resins as received from the manufacturer, according to requirements of California's South Coast Air Quality Management District Method 309-91, Determination of Static Volatile Emissions, revised February 1993. 1.2 This test allows fabricators using polyester and vinyl ester resins to monitor volatile organic compound emissions (principally styrene monomer) fr om resins used in the fabrication process. The results are to be reported as volatile organi c compound losses in grams per square meter (gm/m 2 ). 2. METHOD The weight of a one gallon can lid filled with 100 grams of re sin is accurately measured over a period of time. The measurement is made on resi n catalyzed with peroxide initiators to determine weight losses attributed to monomer and other volatile organic compound emissions.

3. EQUIPMENT REQUIREMENTS 3.1 Controlled environment at 25.0 degrees Celsiu s and humidity of 50 percent relative humidity. If controlled environment is not available, report condition under which measurements are made.
3.2 Balancewith an accuracy of 0.01gram.
3.3 Draft free enclosure for balance. This can be achieved by placing the balance in a four sided enclosure that extends a minimum of eight inches above the top of the balance.
3.4 Gallon can lid with deep form sufficient to contain 100 grams of resin, having a normal diameter of 14.5 centimeters. 3.5 Certified or calibrated thermometercapable of measurements accurate to 1 degree Celsius.
3.6 Constant temperature bath controlled at 25 degrees Celsius to adjust resin temperature to 25 degrees Celsius.
3.7 Timer - capable of recording time to 0.1 minute.
3.8 Paper clip - bent to approximately 90 degree angle. 3.9 Syringe or pipetteaccurate to 0.1 milliliter for peroxide catalyst addition.Santa Barbara County APCD Rule 349 Attachment A - 2 June 21, 2012 4. PROCEDURE 4.1 Weigh out 200 grams of prepromoted resin into a suitable dry and clean container. Wax cups should not be used for this test. 4.2 Cover container and place in constant temperature bath and adjust resin temperature to 25 degrees Celsius. 4.3 Place balance in draft free enclosure. 4.4 Clean gallon lid with solvent, wipe dry and air dry and measure diameter to the nearest 0.1centimeter. 4.5 Place gallon can lid on an inverted paper or plastic cup mounted on the balance pan. Position bent paper clip in the center of the gallon can lid. Record TARE WEIGHT to 0.01gram. 4.6 Take container with resin from water bath an d add appropriate volumetric or weight measure of catalyst using syringe or pipette. Start timer. 4.7 Using stirring rod or thermo meter, mix in catalyst for one minute. 4.8 Pour 100.0 plus or minus 0.5 gram of catalyzed re sin into can lid and record weight to plus or minus 0.01 gram. This is the INITIAL WEIGHT. 4.9 Using paper clip, determine when resin has hard ened sufficiently to allow re sin or lid to be lifted or the gel to be torn. 4.10 Record this as gel time. 4.11 Allow resin to harden in can lid and reweigh every 15 minutes until concurrent weighing agrees to within 0.05gram. Record this as FINAL WEIGHTto plus or minus 0.01gram. 4.12 Procedure should be rep eated until duplicate samples agree to the nearest 5 grams per meter 2

5. CALCULATION 5.1 Volatile Organic Compound Emissions per Square Meter ( d /2) 2x 3.14 Area of Gallon Can Lid in m 2 = 10,000 cm2/ m2

Where: d = diameter of the gallon can lid in centimeters (cm) 3.14 = value of Pi cm2 = square centimeters m 2 = square meters Volatile Organic Compound Losses, Grams per Square Meter = INITIAL WEIGHT - FINAL WEIGHT Area of Gallon Can Lid in Square MetersSanta Barbara County APCD Rule 349 Attachment A - 3 June 21, 2012 5.2 Percent Volatile Organic Compound Emission = INITIAL WEIGHT - FINAL WEIGHT x 100 INITIAL WEIGHT - TARE WEIGHT

6. REPORTING REQUIREMENTS 6.1 Ambient temperature and humidity. 6.2 Resin identification and batch number. 6.3 Initiator system and amounts used. 6.4 Volatile organic compound losses as grams per square meter. 6.5 Percent volatile organic compound emission. 6.6 Gel time under conditions of test.
