STATIC METHOD FOR DETERMINATION OF VOLATILE EMISSIONS FROM

POLYESTER AND VINYL ESTER RESINS

1. PURPOSE

1.1 This test is designed for th e determination of volatile organic compound emissions of polyester and vinyl ester resins as received from the ma nufacturer, according to requirements of California's South Coast Air Quality Management District (SCAQMD) proposed Rule 1162 amendment published July 17, 1990Method 309-91, Determinat ion of Static Volatile Emissions, revised February 1993

.

1.2 This test allows fabricators us ing polyester and vinyl ester resi ns to monitor volatile organic compound emissions (principally styrene monomer) from resins used in the fabrication process. The results are to be reported as volatile organic compound losses in grams per square meter (gm/m 2 ).

2. METHOD

The weight of a one gallon can lid filled with 100 gm grams of resin is accurately measured over a period of time. The measurement is made on resin 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 C degrees Celsius and humidity of 50 % R.H percent relative humidity . If controlled environment is not available, report condition under which measurements

are made.

3.2 Balance with an accuracy of 0.01 gmgram

.

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 eigh t inches above the top of the balance.

3.4 Gallon can lid with deep form sufficient to contain 100 gm grams of resin, having a normal

diameter of 14.5 cmcentimeters

.

3.5 Certified or calibrated thermometer capable of measurements accurate to 1 degree CCelsius

.

3.6 Constant temperature bath controlled at 25 °C degrees Celsius to adjust resin temperature to

25 °C degrees Celsius

.

3.7 Timer - capable of recording time to 0.1 min ute

.

3.8 Paper clip - bent to approximately 90 ° degree angle.

3.9 Syringe or pipette accurate to 0.1 ml milliliter for peroxide catalyst addition.Santa Barbara County APCD Rule 349 Attachment A - 2 April 27, 1993[ date of amended rule adoption ] 4. PROCEDURE

4.1 Weigh out 200 gm 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 tempe rature bath and adjust resin temperature to 25 °C 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 0.1

cmcentimeter

.

4.5 Place gallon can lid on an in verted 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 0.01 gmgram

.

4.6 Take container with resin from water bath a nd add appropriate volumetric or weight measure of catalyst using syringe or pipette. Start timer. (continued)

4.7 Using stirring rod or thermomete r, mix in catalyst for one minute.

4.8 Pour 100.0 +/- plus or minus 0.5 gm gram of catalyzed resin into can lid and record weight to +/- plus or minus 0.01 gmgram . This is the INITIAL WEIGHT.

4.9 Using paper clip, determine when resin has hardened sufficiently to allow resin 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 unt il concurrent weighing agrees to

within 0 .05 gmgram

. Record this as FINAL WEIGHT to +/- plus or minus 0.01 gmgram

.

4.12 Procedure should be repeated until duplicate samples agree to the nearest 5 gm per m 2 grams per

meter 2

.

5. CALCULATION

5.1 Volatile Organic Compound Emissions per Square Meter

( d /2) 2 x 3.14 Area of Gallon Can Lid in m 2

= 10,000 cm 2 / m 2

Area of Sample in Square Meter = (d/2) 2 * 3.14

Where: d = diameter of the gallon can lid in centimeters (cm)

3.14 = value of Pi

cm 2 = square centimeters

m 2 = square meters

Volatile Organic Compound Losses , Grams per Square Meter = INITIAL WEIGHT - FINAL WEIGHT
