PU to Metal Bonding Agent 840
1. Description
840 a single-coat adhesive used to bond various elastomer compounds to substrates during the vulcanization process. It is composed of a mixture of polymers and organic compounds dissolved or dispersed in an organic solvent system. This adhesive system will bond compounds based on Cast polyurethane (CPU) and Millable polyurethane (MPU) polymers to metal. 840 is a surface treatment agent for bonding of polyurethane elastomer-to-metal.
2. Applicable Range
Used as a single-coat adhesive and in combination with a primer adhesive. Suitable for the following types of elastomer:
Cast polyurethane (CPU), Millable polyurethane (MPU), etc. Suitable for the following substrates:
Metal: carbon steel, stainless steel, aluminum and various alloys, etc.
3. Features and Benefits
Single component, easy to operate.
Excellent construction performance.
Excellent high temperature resistance.
Excellent weathering resistance - heat, water, solvent, oil, salt spray and corrosion resistance.
4. Typical Properties
Appearance: Amber Liquid
Viscosity, cps @ 25°C (77°F) Brookfield LVT Spindle 2, 12 rpm: 700-1100
Solids Content by Weight, %: 18-22
Flash Point (Seta), °C: 2
Solvents: Toluene, Isopropanol, Ethyl alcohol
Components: Polymers, organic compounds, and organic solvents
5. Application
Stirring: 840 does not require stirring before or during use.
Diluting: According to the actual operation needs, this product can also add diluent (Toluene: isopropyl alcohol =1:1) for appropriate dilution. It is recommended to dilute the diluted product according to the amount used. The diluted product cannot be stored for a long time.
Brush coating method: no dilution is required.
Roller coating method: no dilution is required.
Dip: 100 parts of 840 plus about 50-100 parts of diluent.
Spray method: 100 parts 840 plus about 50-100 parts diluent.
Coating: This product can be applied by brush coating, dip coating, roll coating, spray coating and other methods. Coating should be uniform to avoid excessive spillover.
Single coating: Dry film thickness(DFT) 15-30 μm；
Drying: At 25°C, drying takes about 45-60 minutes and forced drying can shorten the drying time.
Pre drying: To ensure cohesion strength, the coated workpiece should be baked at 120°C for at least 2 hours. Large workpieces need to extend the baking time at 120°C to reduce the heat sink effect.
Product storage: This product should be stored in dry and normal temperature environments, avoid long-term exposure to high humidity and high temperature environment.
Vulcanization: Simultaneous vulcanization of polyurethane elastomer and treatment agent can achieve the best adhesive performance, and the actual vulcanization conditions are the same as those of polyurethane materials. The effect is better when the vulcanization temperature is above 75°C.
6. Shelf Life & Storage
Shelf life is 12 months from date of shipment when stored at 21-27°C (70-80°F) in original, unopened container. Do not store or use near heat, sparks or open flame.
7. Precautions
1. This product is volatile, please close the container after use.
2. Solvent steam is harmful, pay attention to fire prevention in the workplace, pay attention to low ventilation, prevent long-term inhalation or long-term skin contact.
3. Please refer to SDS for more safety information.
