2. Harwal Polyurethane Systems HP – SP - 3040 of the foam insulation. To obtain optimum results, system should be spray - applied to substrates when ambient air and surface temperatures are between 10ºC and 50°Cº. All substrates to be sprayed must be free of dirt, soil, grease, oil and moisture prior to the application of HP Spr ay. Moisture in any form: excessive humidity (>85%R.H.) rain, fog, or ice will react chemically will adversely affect system performance and corresponding physical properties. Application should not take place when the ambient temperature is within 3°C of the dew point. Wind velocities in excess of 20 km per hour may result in excessive loss of exotherm and interfere with the mixing efficiency of the spray gun affecting foam surface texture, cure, physical properties and will cause overspray. Precautions mu st be taken to prevent damage to adjacent areas from fugitive overspray. Applicators should ensure the safety of the jobsite and construction personnel by posting appropriate signs warning that all "hot work" such as welding, soldering, and cutting with to rches should take place no less than 35 feet from any exposed foam. If "hot work" must be performed all spray polyurethane foam should be covered with an appropriate fire or welder's blanket, and a fire watch should be provided. Processing Equipment: 2:1 transfer pumps are recommended for material transfer from container to the proportioner. The plural component proportioner must be capable of supplying each component within ± 2% of the desired 1:1 mixing ratio by volume. Hose heaters should be set to del iver 50°C to 55°C materials to the spray gun. These settings will ensure thorough mixing in the spray gun mix Chamber in typical applications. Optimum hose pressure and temperature will vary with equipment type and condition, ambient and substrate conditio ns, and the specific application. Some equipment may require you to heat drums to achieve optimum material temperature. It is the responsibility of the applicator to properly interpret equipment technical literature, particularly information that relates a cceptable combinations of gun chamber size, proportioner output, and material pressures. The relationship between proper chamber size and the capacity of the proportioner ’s pre - heater is critical. Contact your machine supplier representative for specifi c recommendations, pricing, and availability of spray and auxiliary equipment. Per Pass Application: Applicators should limit HP Spray thickness to 2,5 cm per pass for optimal processing and physical properties. Edition – 02, October 20 21 Page 2 of 3

7. Harwal Polyurethane Systems HP – SP - 3040 For disposal within the EC, the appropriate code according to the European Waste Catalogue (EWC) should be used. After containers have been emptied as thoroughly as possible (e.g. by pouring, scrapi ng or draining until "drip− dry"), they can be sent to an appropriate collection point set up within the framework of the existing take−back scheme of the chemical industry. Containers must be recycled in compliance with national legislation and environment al regulations. 14.

Safety precautions for handling freshly molded polyurethane parts: Depending on the production parameters, any uncovered surfaces of polyurethane moldings produced using this raw material may contain traces of substances (e. g. starting and reaction products, catalysts,) with hazardous characteristics. Skin contact with traces of these substances must be avoided. When demolding or otherwise handling freshly molded polyurethane pa rts, protective textile gloves must be worn as a minimum. Their palm and finger areas should preferably be coated on the outside with nitrile rubber, PVC or polyurethane. Protective gloves should be changed daily. The wearing of protective clothing suited to the conditions normally encountered when handling freshly molded polyurethane parts is recommended. The presented Safety Data Sheet has been altered. The reason for the alteration is as follows: revised text (see chapter 2, 4, 5, 6, 7, 8, 9, 11, 12, 15 and 16) This safety data sheet replaces all previous information.

Recommended storage temperature: 25°C Labeling and REACH applications This product data sheet is only valid in conjunction with the latest edition of the correspondin g Safety Data Sheet. Any updating of safety - relevant information in accordance with statutory requirements will only be reflected in the Safety Data Sheet, copies of which will be revised and distributed. Information relating to the current classif ication and labelling , applications and processing methods and further data relevant to safety can be found in the currently valid Safety Data Sheet. Directions for Processing HP – SP - 3040 system is designed for processing on high and low pressure mac hines that are able to work at mixing ratios of 1:1 by volume, the machine parameters have to be selected in such way to ensure proper mixing. Environmental Consideration and Substrate Temperatures: Applicators must recognize and anticipate climati c conditions prior to application to ensure highest quality foam and to maximize yield. Ambient air and substrate temperatures, moisture and wind velocity are all critical determinants of foam quality. Extreme ambient air and substrate temperature will influence the chemical reaction of the two components, directly affecting the yield, adhesion, and the resultant physical properties Edition – 02, October 20 21 Page 1 of 3
