Customer Questions & Answers
-
Question:
What is Sikaflex-291 LOT used for?
Answer: Sikaflex-291 LOT is a versatile marine adhesive and sealant designed for bonding and sealing applications. It is suitable for use on various substrates, including wood, metal, glass, and fiberglass, making it ideal for marine and automotive uses. Its exceptional adhesion properties help secure components like hulls and decks, while its long open time allows for adjustments during application. Whether you're constructing a boat, repairing a leak, or building a custom structure, Sikaflex-291 LOT ensures a strong, flexible bond that withstands harsh marine environments. -
Question:
What makes Sikaflex-291 LOT a marine-grade adhesive?
Answer: Sikaflex-291 LOT is classified as a marine-grade adhesive due to its excellent resistance to water, UV rays, and harsh weather conditions. Its special formulation allows it to expand and contract without losing adhesion when subjected to temperature variations and moisture. This makes it particularly useful for marine applications such as sealing joints on boats and yachts. For boat owners or marine professionals looking for a reliable bonding solution, Sikaflex-291 LOT is a superior choice that delivers durability and longevity in marine environments. -
Question:
Is Sikaflex-291 LOT paintable?
Answer: Yes, Sikaflex-291 LOT can be painted over once fully cured. It is recommended to allow the adhesive to cure completely before applying paint, as doing so ensures optimal adhesion of the paint to the sealant. Additionally, using compatible paints will help maintain the integrity and appearance of the cured sealant. This makes it an excellent option for those wishing to blend the adhesive with surrounding finishes in automotive or marine projects. -
Question:
How does the long open time of Sikaflex-291 LOT benefit users?
Answer: The long open time of Sikaflex-291 LOT, which allows for an extended working period before curing, is a significant advantage for users. This feature enables precise applications, adjustments, and alignment without the pressure of fast curing. It is particularly beneficial for detailed work or complex assemblies, where making adjustments is crucial for achieving the desired results. This flexibility helps ensure that every aspect of your project is executed perfectly. -
Question:
Can Sikaflex-291 LOT be used underwater?
Answer: Sikaflex-291 LOT is not designed for underwater applications, as it requires time to cure in atmospheric moisture. It performs optimally when applied to dry surfaces. For below-waterline applications, consider preparing the surface in a way that allows the adhesive to bond effectively before exposure to water. Its properties allow for excellent adhesion once cured, making it suitable for use in the vicinity of water but not for direct underwater bonding. -
Question:
What substrates can Sikaflex-291 LOT bond to?
Answer: Sikaflex-291 LOT can bond to a wide variety of substrates, including wood, metals, glass, fiberglass, and some plastics. This broad compatibility makes it an excellent choice for different applications, particularly in marine and automotive industries. Users can confidently rely on this adhesive for projects involving multiple materials, ensuring a strong and lasting bond that meets their specific needs. -
Question:
How should Sikaflex-291 LOT be stored?
Answer: To maintain the effectiveness of Sikaflex-291 LOT, it should be stored in a cool, dry place, ideally between 5°C and 25°C (41°F and 77°F). Keeping the adhesive in its original, sealed packaging will help prevent contamination and extend its shelf life. Users should avoid exposing the product to extreme temperatures or direct sunlight. Proper storage is essential for ensuring optimal performance when the adhesive is needed for bonding or sealing tasks. -
Question:
Can Sikaflex-291 LOT be used for automotive applications?
Answer: Absolutely! Sikaflex-291 LOT is suitable for various automotive applications, including bonding body panels, sealing windshields, and fixing other components exposed to moisture or vibration. Its robust adhesion and flexibility make it ideal for applications where movement may occur. Car restorers and enthusiasts often choose this adhesive for its performance and reliability in demanding automotive environments, providing peace of mind in their repairs and projects. -
Question:
What safety precautions should be taken when using Sikaflex-291 LOT?
Answer: When using Sikaflex-291 LOT, it's important to follow safety precautions such as wearing gloves and ensuring sufficient ventilation in the working area. The adhesive can emit fumes during application, which could irritate the respiratory system. Users should also avoid contact with skin and eyes to prevent irritation. Always refer to the product’s safety data sheet (SDS) for specific handling instructions and potential hazards to maintain a safe working environment. -
Question:
Where can I buy Sikaflex-291 LOT in India?
Answer: You can purchase Sikaflex-291 LOT at Ubuy in India.

SIKA Urethane Adhesives Editorial Review
**** The customer reception of Silkaflex sealant displays a dual perspective, characterized by both praise and frustration from various users. Many customers appreciate its sticking power and versatility, particularly for automotive and marine applications. Users reported successfully applying the sealant in challenging situations such as underbody car sealing and restorations of vintage vehicles — leading to initial positive impressions of its adhesion and finish. Several were satisfied with its durability, noting that it appears promising even after short-term application. However, mixed reviews emerge regarding the workability and cleanup of the product. While its ability to bond well is acknowledged, some users found the thick Consistency difficult to spread and manipulate, resulting in uneven surfaces. A notable concern was raised about the cleanup of tools and excess product, which was reported to stick tenaciously and resist all attempts at removal. Some experiences hinted at a prolonged drying time, contributing to a sense of dissatisfaction, especially in scenarios where a smooth and professional finish was paramount. Overall, while Silkaflex is esteemed for its strong adhesive properties and reliability in preventing leaks, it may not meet the expectations of users who seek a more manageable application process and easier cleanup. **
