IMPORTANT INFORMATION: READ BEFORE USING PRODUCT
Directions for use: Stir contents prior to use. Because of differences in density, pigments and fillers, when
present, may separate from the liquid components during storage. To insure product homogeneity and maximum
performance, check the containers for settling. If settling is evident, loosen any settled pigments from the bottom of the
container with a screwdriver or similar object. Hand-stir the contents with a metal mixing stick, or power mix at slow
speed with a drill press and dispersion blade. This product might crystallize in its shipping container during storage. If
it appears hard, or has a granular consistency, or if it is normally clear but appears cloudy, warm it thoroughly at 120oF
to reconstitute. Re-mix the product and allow it to cool back to room temperature before using.
Measuring: Carefully weigh Part A and Part B components with an accurate scale. If measuring volumetrically, use
precise metering pumps, graduated/pre-marked containers or pre-measured kits. Place the correct proportions of Part A
and Part B into a straight-sided container. Note: Altering the mix ratio from what is specified on the data sheet is not
recommended. Cured properties could be adversely affected.
Mixing: Mix thoroughly with a flat-ended stick or a slow speed drill press with a dispersion blade. Scrape the sides and
bottom occasionally to assure a thorough blend. Do not whip excessive air into the mixture. To guard against partially
cured sections, never apply material scraped from the sides of the original mixing container. For best results, transfer
the mixture into a second container and stir it again before application. This will help insure consistent properties and
maximum performance.
De-airing: Low viscosity resins will de-air naturally on their own. Some applications require a totally
air-free product. If a vacuum pump and chamber are used, evacuate the material for 5-15 minutes @ 28-29 inches of
mercury. Allow sufficient space above the liquid for expansion, about four times the liquid volume. Resins slightly
warmed are thinner and will de-air faster. Also, the use of an air-out additive will lower the surface tension and hasten
air release. Caution: Warming a catalyzed mixture will shorten the pot life and hasten gel time.
Storage: Store the product away from sunlight and open flames, at a stable temperature of less than 85oF. Cooler
temperatures will extend shelf life, but may contribute to crystallization or freezing of the resin. Keep containers tightly
closed when not in use. Air and moisture will decrease shelf life and will adversely affect properties.
Handling Cautions: Review the Material Safety Data Sheet before using this product.
Warning: For Industrial Use Only. All chemicals must be handled with care. Avoid breathing fumes, mists and dust,
they could cause respiratory discomfort or damage. Work in a well-ventilated area. Avoid all contact with the skin. If
contact occurs, wash affected area thoroughly with soap and water. Repeated skin contact may cause dermatitis in
susceptible individuals. Wear protective clothing and gloves. Severe irritation will result if this product is splashed into
the eyes. Always wear eye protection. If eye contact occurs, flood eyes with clear water for 15 minutes and immediately
seek medical attention. Always maintain good industrial hygiene when using this product.
