Manufacturer: Siplast Accepted for RoofStar Guarantee Program Date TBA Product Summary A multi-component PMMA flashing resin for use in the Parapro 123 Flashing System. Parapro Flashing Resin is a high performance, multi-component, flexible PMMA resin for use in the Parapro 123 Flashing System. Uses Parapro Flashing Resin, when catalyzed, is combined with polyester fleece to form a monolithic, reinforced flashing membrane used with a variety of Siplast roofing and waterproofing systems for flashing and repairs. Colour Parapro Flashing Resin is supplied in a standard light gray colour #7035. Contact the Siplast Technical Department for information on other colour finishes. Packaging Parapro Flashing Resin is supplied in 5 kg (11 lb) re-sealable drums with locking ring. Coverage Rate Flashings - Minimum consumption 0.31 kg/sf (3.3 kg/m²) Base Coat - Minimum consumption 0.19 kg/sf (2.0 kg/m²) Top Coat - Minimum consumption 0.12 kg/sf (1.3 kg/m²) See recommendations for specific applications. Yields will vary depending upon the system selected and the smoothness and absorbency of the substrate. Application Conditions Parapro Flashing Resin is available in summer and winter grades. Care should be taken to ensure that the correct formulation is used for the application based upon the ambient temperature. Summer Grade: Summer Grade Parapro Flashing Resin can be applied when the ambient temperature is between 59°F (15°C) and 104°F (40°C) and the substrate temperature is between 50°F (10°C) and 122°F (50°C). Discontinue membrane application when the ambient temperature exceeds 104°F (40°C) and / or the substrate temperature exceeds the 122ºF (50ºC) maximum, or provide adequate shade to the substrate area for up to one hour prior to and during application as necessary to maintain surface temperatures below the maximum. Winter Grade: Winter Grade Parapro Flashing Resin can be applied when the ambient temperature is between 23°F (-5°C) and 68°F (20°C) and the substrate temperature is between 23°F (-5°C) and 77°F (25°C). Storage Store closed containers in a cool, dry area away from heat, direct sunlight, oxidizing agents, strong acids, and strong alkalis. Keep away from open fire, flame, or any ignition source. Store indoors in a well ventilated area. Do not store in temperatures below 32ºF (0ºC) or above 85ºF (29ºC). The resin may auto-polymerize at temperatures greater than 140ºF (60ºC). Shelf life may be reduced if product is stored above 85ºF (29ºC). Materials stored on the roof during application should be kept on a pallet in a shaded, well ventilated area. In un-shaded areas, materials should be covered with a white, reflective tarp in a manner that allows air circulation underneath the tarp. Mixing & Catalyzing Thoroughly mix the entire drum of resin for 2-3 minutes before each use and prior to pouring off resin into a second container if batch mixing. Catalyze only the amount of resin that can be used within the anticipated pot life of the material. Add pre-measured catalyst to the resin component, and stir for 2 minutes using a slow-speed mechanical agitator or stirring stick. The amount of catalyst added is based on the weight of the resin used, as shown in the chart. Pot Life Parapro Flashing Resin pot life is approximately 15 minutes at 68°F (20°C). Because pot life is in large part dependent on ambient temperature, which constantly changes, actual pot life must be determined in the field. Pot life will be reduced at high temperatures. Set Times Minimum set times noted below are approximate and may vary. The information provided is based on laboratory conditions, and is intended for use as a guideline only. Actual set times and cure times should be established in the field, based on actual field conditions. Rain Proof at 68°F (20°C): Approximately 30 minutes. Ready for Next Coat at 68°F (20°C): Approximately 45 minutes. Ready for Foot Traffic at 68°F (20°C): Approximately 2 hours. Tool Cleaning When work is interrupted or completed, reusable tools must be thoroughly cleaned with Pro Prep before any catalyzed resin on the tools hardens. Handling Do not smoke. Keep away from open fire, flame or any ignition source. Vapors may form explosive mixtures with air. Avoid skin and eye contact with this material. Avoid breathing fumes. Do not eat, drink, or smoke in the application area. Consult the Material Safety Data Sheet for additional information pertaining to this product. Personal Protection Equipment (PPE) Workers must wear a long sleeved shirt with long pants and work boots. Workers must use only butyl rubber or nitrile gloves when mixing or applying this product. Safety glasses with side shields are required for eye protection. Use local exhaust ventilation to maintain worker exposure below TLV. If the airborne concentration poses a health hazard, becomes irritating, or exceeds recommended limits, use a NIOSH approved respirator in accordance with OSHA Respirator Protection requirements under 29 CFR 1910.134. Specific type of respirator will depend on the airborne concentration. A filtering face piece or dust mask is not acceptable for use with this product if TLV filtering levels have been exceeded. Summer Grade Parapro Flashing Resin Catalyst Mixing Measurements The amount of Pro Catalyst used with Parapro Flashing Resin varies from a minimum of 2% to 4% maximum by weight, depending upon the ambient temperatures as indicated in the following table: Resin Quantity Summer Grade 2% Catalyst 68°F to 104°F (20°C to 40°C) Summer Grade 4% Catalyst 59°F to 68°F (15°C to 20°C) g kg Tblsp. g kg Tblsp. 1 kg (0.7 litre) 20 .02 2 40 .04 4 5 kg (3.5 litre) 100 0.1 10 200 0.2 20 Winter Grade Parapro Flashing Resin Catalyst Mixing Measurements The amount of Pro Catalyst used with Parapro Flashing Resin varies from a minimum of 2% to 4% maximum by weight, depending upon the ambient temperatures as indicated in the following table: Resin Quantity Winter Grade 2% Catalyst 59°F to 68°F (15°C to 20°C) Winter Grade 4% Catalyst 23°F to 59°F (-5°C to 15°C) g kg Tblsp. g kg Tblsp. 1 kg (0.7 litre) 20 .02 2 40 .04 4 5 kg (3.5 litre) 100 0.1 10 200 0.2 20
