Polyurethane Spray System, WANEFOAM®6012b

Product Introduction

The WANEFOAM®6012b series is a polyurethane rigid foam spraying combination material. Its foaming agent is an environmentally friendly foaming agent with an ultra – low thermal conductivity. When used in combination with WANNATE®2208, it can be applied to cement surfaces, brick surfaces, wood surfaces, and other substrates. It has strong adhesion, good product dimensional stability, and excellent flame – retardant performance. The combustion grade is B1 or B2 (GB 8624 – 2012).

Product Use

The product is applied to various spraying fields with a working temperature above – 25°C, such as cold storage and building interior insulation, and is mainly used for ground heat insulation. The WANEFOAM®6012b polyurethane spraying material is a fast – curing system, which meets the construction requirements of most spraying insulation fields. Before using the WANEFOAM®6012b series of spraying materials, tests must be carried out first to ensure the reliability of the combination material system for use in specific projects.

Physical Properties

Notes:

(1) WANEFOAM®6012b is foamed in combination with WANNATE®2208. The material temperature is 25°C, the volume ratio of materials is 1:1, and they are mixed manually using an electric stirrer (2500r/min).
(2) Operate in accordance with the precautions in this document. The overall density of the foam product obtained by the high – pressure spraying machine is greater than 40kg/m³.
(3) The values provided in this document are typical test values. Specific data may vary slightly due to environmental conditions. For our company’s products, the listed data has no legal binding force.

Precautions for Use

The construction equipment for WANEFOAM®6012b polyurethane rigid foam spraying material is a high – pressure spraying machine. Before construction, please check and calibrate the delivery ratio of black and white materials and the mixing pressure of the high – pressure spraying machine.
The ambient temperature for spraying operations should be 10 – 40°C, the wind speed should not be greater than 5m/s (grade 3 wind), the relative humidity should be less than 75%, and construction is not allowed in rainy days. When the ambient temperature during construction is lower than 10°C, reliable technical measures should be taken to ensure the spraying quality.
During spraying operations, control the temperature of black and white materials entering the spray gun to be greater than 30°C, and ensure that the substrate is dry and clean. Control the thickness of each spray of foam within the range of 1 – 2cm (excluding the primer layer). During construction, the next layer can only be sprayed after the surface of the previously sprayed polyurethane rigid foam is no longer sticky. Other relevant standards shall be implemented in accordance with national standards. If the above conditions are not met, all responsibilities shall be borne by the buyer.
Spraying operations shall be carried out in accordance with GB 50404 – 2017 “Technical Code for Rigid Foam Polyurethane Thermal Insulation and Waterproof Engineering”.
The construction site should be a fire – prohibited area with good ventilation, away from fire sources, and smoking is strictly prohibited. When there is hot work nearby, the hot work approval system must be strictly implemented, and corresponding safety measures and dedicated supervision should be taken.
Before formal construction of the project, the buyer must conduct tests in an environment consistent with the construction conditions to ensure the reliability of the combination material system for use in specific projects. During formal construction, it is considered that the buyer has recognized the qualified performance inspection of the product. If the above operations are not followed, all responsibilities shall be borne by the buyer.

Packaging Specifications

200L green iron drums.

Storage (Use) Precautions

The combination material should be stored in a closed container to avoid absorbing water vapor. Therefore, during storage and transportation, the dryness and sealing of the container must be ensured.
The WANEFOAM®6012b polyurethane rigid foam spraying material should be stored in a sealed manner at a room temperature of 5 – 35°C in a well – ventilated and cool place, avoiding direct sunlight or long – term storage above 40°C to prevent a large amount of foaming agent from volatilizing, which may affect storage and product performance.

Shelf Life

Under suitable storage conditions, the shelf life of the WANEFOAM®6012b polyurethane rigid foam spraying material is 3 months. After 3 months, it can be used continuously after passing the inspection.

Safety Precautions

Direct contact with WANEFOAM®6012b polyurethane rigid foam spraying material can cause moderate eye irritation and mild skin irritation, and may cause skin allergies. Repeated inhalation of high – concentration vapors can cause respiratory allergies. Seek medical attention immediately and take anti – inflammatory, anti – allergic and other symptomatic treatment measures.
Operate with caution to prevent direct contact with the skin and splashing into the eyes. Wear necessary protective equipment (gloves, safety glasses, work clothes, etc.).
Once splashed on the skin or in the eyes, rinse immediately with clean water for at least 15 minutes. Wash the skin with soapy water, and seek medical attention if necessary. In case of ingestion, seek medical attention immediately for symptomatic treatment.

Fire and Explosion Hazards

This product is not a flammable liquid, explosive, oxidizer, corrosive, toxic, or radioactive dangerous product during storage and transportation, and is not a dangerous product.
Fire – fighting Media: Carbon dioxide, foam, or chemical dry powder fire extinguishers can be used for fire – fighting. When there are no other fire – fighting agents, a large amount of water mist can be sprayed. Once the fire is extinguished, the spilled materials should be cleaned up (see Leak and Spill Handling).
Fire – fighting Procedures: Normal protection.

Leak and Spill Handling

Small amounts of leaked and spilled materials can be washed away with water. In case of a large leak, collect and recycle, and wash the contaminated ground with water or detergent. The disposal of waste combination materials must comply with local government environmental protection regulations.
