RESOURCES + FAQs

  • Technical Data
  • Why offer a sealant designed for windows, doors & trim?

    Windows, doors and trim are among the top applications for sealant for both Pros and DIYers. Many times consumers choose acetoxy silicone technology for exterior applications on these projects, however DYNAFLEX 230® meets performance standards of acetoxy silicone with the added benefits of being paintable, low odor, easy to tool and easy to clean up with soap and water. It is engineered with increased elongation by 33% to deliver increased toughness for outstanding performance against the elements.

    What does “Silicone Tough” mean?

    Based on laboratory testing, DYNAFLEX 230® delivers the performance characteristics of acetoxy silicone, but with all of the advantages of a latex sealant (paintable, low odor, easy to tool and easy to clean up with soap and water). Beyond meeting the ASTM C920 Class 25 test standard (demonstrating over 50% total joint movement in extreme temperatures), the DYNAFLEX 230® also meets the same stress/strain tests as acetoxy silicone.

    What is “Composite” molding and why is it important?

    The term “composite” is a term used to describe synthetic building materials (including polystyrene, MDF and others). The synthetic building materials market is a $3 billion industry and is growing quickly, especially with molding and trim. Usage of composite and PVC trimboard has become common, and few sealants are able to claim compatibility with this category of materials.

    What colors does DYNAFLEX 230® come in?

    DYNAFLEX 230® comes in a wide variety of colors to match the most popular colors of exterior siding and trim. Colors include: white, clear, almond, gray, clay, cedar tan, brown, bronze and black.

    How long is the shelf life on this product?

    A minimum of 12 months from the date of production in an unopened tube

    Can I use this in a shower?

    No. The product is not applicable for use in a bath or shower.
