Cure Schedule 6 hours At 185°F, (85°C) 2 hours At 185 plus 3 hours At 300°F, (149°C) - Directions for use
Stir contents prior to use. Because °F 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 °F 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 120°F to reconstitute. Remix 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 °F Part A and Part B into a straight-sided container. Note: Altering the mix rati°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 °Ccasionally 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 °F 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 At 28-29 inches °F 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 °F an air-out additive will lower the surface tension and hasten air release.
Caution: Warming a catalyzed mixture will shorten the pot life and decrease gel time.

Safety & Health
- 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 °Ccurs, 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 °Ccurs, flood eyes with clear water for 15 minutes and immediately seek medical attention. Always maintain good industrial hygiene when using this product.
Storage & Handling
- Shelf Life
- 1 year
- Storage
Store the product away from sunlight and open flames, at a stable temperature °F less than 85°F. Cooler temperatures will extend shelf life, but may contribute to crystallization or freezing °F the resin. Keep containers tightly closed when not in use. Air and moisture will decrease shelf life and will adversely affect properties.
