GENERAL SPECIFICATIONS

• System with high mechanical properties covering the surfaces, easy to apply using our our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar.
• With its continuous application, joints and any type of union between applications are saved, providing a surface with optimal protection parameters.
• The blowing agent is water. The gas occluded in the internal cells of the product formed is CO2, coming from the reaction between the water contained in the polyol and the isocyanate.
• the properties of this polyurethane foam system allow it to adhere to any surface such as concrete, ceramic, metal, polyurethane foam, wood, acrylic paints (checking the situation of areas recommended)
• it is free from harmful to the ozone layer, so do not promote the greenhouse effect (NOT contain HFCs, HCFCs, VOCs, etc ...). The sytem is 100% recyclable by mechanical means friendly to the environment. No gas collection for recycling and/or destruction is required. it does not emit any substance to the environment once installed.
• Recommended thickness: 5 -10 mm
• Contractors and applicators must comply with all applicable and appropriate guidelines for processing, handling guidelines.

PACKAGING

Metal drums of 220 kg for the polyol, and 250 kg for the isocyanate.

SHELF LIFE

• POLYOL COMPOUND: 6 months
• ISOCYANATE COMPOUND: 6 months

Always store the drums before use at a temperature between 5 ºC and 35 ºC (41 ºF to 95 ºF),always in dry areas, without the possibility of moisture entering, and without direct contact with the sun or heat sources, otherwise they may be affected its reactivity and performance. Low ambiance temperature increase the viscosity of the polyol, which makes it difficult to mix and apply, and can generate crystallization in the isocyanate, which can cause its mixing ratio to vary and the consequent internal problems in the mixing and application equipment .

APPLICATION METHOD

In general, you should take the following factors:

• the application of this polyurethane foam system  should be performed under the non-presence of moisture or water from the support stand on which to apply either at the time of application as a posteriori.
• the substrate must be clean and free of dust, oils or greases. The polyurethane foam system adheres strongly to most common building materials such as wood, steel, OSB, plywood, fiber cement, interior masonry, itself and on lower density systems polyurethane.
• metal surfaces should be protected with an anti-rust primer before being covered with foam. On smooth surfaces without pores, galvanized sheet, polypropylene, etc..., a primer must be applied to ensure adhesion
• in case of existence of expandion joints, they must be covered with a non adhesive plastic tape to avoid breaks in the SPF due to the movement of the support.
• minimum recommended substrate temperature must be 5ºC to 40ºC (41-104ªF)
• in applications with high-temperature gradients, a vapor barrier is placed on the warm side of the insulation to prevent condensation
• the thickness that can be made per layer is approx. 10mm, until the desired total thickness is achieved as successive layers are applied. For the spraying of the next layer, the temperature of the first should be approximately 35-40ºC (95-104ºF)or wait 3-4 minutes for it to drop.
• the desired total thickness must be defined by the project according to its specifications.
• at all times the applicator must comply with local regulations depending on the use, taking into account the physicochemical characteristics of the polyurethane foam system to be used.

APPLICATION REQUIREMENTS (spray equipment)

For the formation, it is necessary to mix the two initial liquid components, isocyanates and polyols with our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar (proper maintenance and cleaning it is recommended).  The general parameters for this material will be the following:

• Isocyanate heater temperature:40-45 ºC (104 to 113ºF)
• Polyol heater temperature:45-55ºC 113 to 131ºF)
• Hose temperature:40-50ºC  (104 to 122ºF)
• Working pressure: 1.450-1.750 psi (100 - 120 bar)
• Mixing chamber (recommended): GU-07008-2

These temperature and pressure parameters must be valued, ratified or slightly varied by the applicator, depending on the conditions of each climatic zone, weather situation or according to the specifications of the projection equipment. It is the responsibility of the owner / applicator of the equipment to keep it in perfect condition in order to maintain the correct mixing ratio of the two components that Tecnopol delivers separately, by periodically updating its maintenance controls. During the execution of the application, it may be necessary to correct these parameters according to changing external conditions, as well as to verify the correct operation of the machine (pressure and temperature).

HEALTH AND SAFETY

These safety recommendations for handling, are necessary for the implementation process as well as in the pre and post, on exposure to the loading machinery.

• Respiratory Protection: When handling or spraying use an air-purifying respirator.
• Skin protection: Use rubber gloves, remove immediately after contamination. Wear clean body-covering. Wash thoroughly with soap and water after work and before eating, drinking, or smoking.
• Eye / Face: Wear safety goggles to prevent splashing and exposure to particles in the air.
• Waste: Waste generation should be avoided or minimized.
• Incinerate under controlled conditions in accordance with local laws and national regulations.
• Re-occupancy of the work site without respiratory equipment is minimum 24 hours providing the correct ventilation for the area sprayed.
• Contractors and applicators must comply with all applicable and appropriate guidelines for storage and safety guidelines.

Consult the material and safety data sheet of the products of the system.
