Sikaflex®-510 AM50
Sikaflex®-510 AM50 is a 1-component, high movement Silane Terminated Polymer (STP) sealant that cures on exposure to atmospheric humidity. It is well suited for applications that require both paintability and adhesion to non-porous substrates.
- Good UV and weathering resistance
- Excellent adhesion to porous and non-porous substrates
- Isocyanate free
- ASTM C-920 for Type S, Grade NS, Class 50

Usage
Sikaflex®-510 AM50 can be used for joints or gaps connecting dissimilar substrates such as vinyl to concrete or aluminum to EIFS. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.Packaging

CURE MECHANISM
Sikaflex®-510 AM50 cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower (see Diagram 1).

Application
Surface Preparation
Surfaces must be clean, dry and free from grease, oil and dust.
Application
Sikaflex®-510 AM50 can be processed between 5 °C and 40 °C but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and sealant is between 15 °C and 25 °C. Sikaflex®-510 AM50 can be processed with hand, pneumatic or electric driven piston guns.
Tooling and finishing
Tooling and finishing must be carried out within the skin time of the product. Dry tooling is recommended. Do not use soapy water or other liquids when tooling.
Overpainting
Sikaflex®-510 AM50 can be painted after formation of a skin.
When overcoating with water, oil and rubber based paints, compatibility and adhesion testing is essential. Rigid paints and coatings may lose adhesion to elastomeric sealants due to their inability to accommodate joint movement.
Application Limits
Maximum depth of sealant must not exceed 13 mm (1/2 in.); minimum depth is 6 mm (1/4 in.).
Not intended for immersion, structural glazing applications, or horizontal vehicular traffic.
Do not apply to damp or wet substrates.
Allow treated wood to age six months before application.
