Moisture pre-curable, heat curing body shop sealant SikaPower-415 P1 is a 1-component, cold-applied, pre-curable, heat-curing sealant based on flexibilised epoxy resin. By exposure to humidity, it forms a skin within 4 hours at ambient temperature. SikaPower-415 P1 is designed for sealing seams or joints in sheet metal assemblies. SikaPower-415 P1 has a good wash-out resistance, which can be improved by skin formation or pre-curing. - Heat-curing 1-component elastic product
- Suitable for sealing different metals (e.g., bare steel, aluminum, zinc-coated steel, etc.)
- Adheres well to oily substrates
- Skin formation by exposure to moisture at ambient temperature
- Good wash-out resistance
- Can be electro- or powder-coated after pre-curing or skin formation
- Does not contain solvents or PVC

PRODUCT BENEFITS - Heat-curing 1-component elastic product
- Suitable for sealing different metals (e.g., bare steel, aluminum, zinc-coated steel, etc.)
- Adheres well to oily substrates
- Skin formation by exposure to moisture at ambient temperature
- Good wash-out resistance

Usage SikaPower-415 P1 is suitable for sealing seams (e.g., laser step seams) and joints for sheet metal assembly works. Bonding of oily substrates (standard anti-corrosion treatments and deep drawing oils up to 3 g/m2) is possible due to oil uptake during the heat curing process. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

Technical Information CURE MECHANISM SikaPower-415 P1 is cured by heat. The cure-rate depends on temperature and time of exposure. The most common heat sources are convection ovens. To avoid blisters, the open time at 23 °C / 50 % r.h. must not exceed 5 days before curing. SikaPower-415 P1 forms a thin skin within approximately four hours (23 °C / 50 % r.h.) after application by the absorption of atmospheric moisture.

Application Information Application SikaPower-415 P1 is typically applied in beads with minimal thickness of 2 mm. After application, the bead is usually flattened or spread. The time between application and curing must not exceed 5 days. However, moisture uptake can be prevented by pre-curing the assembled parts for 5 minutes at 160 °C (substrate temperature). The minimum curing temperature is 160 °C for 15 minutes, whereas the standard curing conditions is 180 °C for 30 minutes, usually in electrocoat ovens. SikaPower-415 P1 can be exposed for a short time to 220 °C for max. 10 minutes. The follower plate and the hoses do not have to be heated. Typically, the application nozzle, last hose and the dosing unit are heated up to 40 °C to get constant application properties. During breaks longer than 4 hours (e.g. overnight or weekends) the heating must be switch-off and the pump system have to be depressurised. Store the product for 24 to 48 hours prior application at the assembly line, to get the product to room temperture, if stored cold (e.g. unheated storage in winter). SikaPower-415 P1 can be processed with hand-, pneumatic- or electric driven piston guns as well as dispensing equipment.
For advice on selecting and setting up a suitable pump system, contact the System Engineering Department of Sika Industry. Overpainting, tooling and finishing For tooling purposes, use small quantities of Sika Tooling Agent N. The joint must be dry prior to the curing or pre-curing process. If SikaPower-415 P1 need to be powder-coated, it must be pre-cured or a at least a thin skin must be present prior to coating. The powder-coating must be tested for compatibility by carrying out preliminary trials. The hardness and the film thickness of the powder-coating may impair the elasticity of the product and could lead to cracking of the coating. STORAGE CONDITIONS SikaPower-415 P1 has to be kept between 5 °C and 25 °C in a dry place. Do not expose it to direct sunlight or frost. After opening of the packaging, the content has to be protected against humidity. If SikaPower-415 P1 is stored at higher temperatures the shelf life will be reduced. Minimum temperature during transportation is -20 °C for max. 7 days. |
