4.03Gently continue pushing the fiber into the splice until resistance is felt. When fully inserted, the first fiber should be straight or have a slight bow – up to .1 inch (3 mm).

Note:

If properly inserted, bare glass should not be visible

 

outside of splice. If bare glass is visible, pull back slightly

 

on fiber and continue insertion until resistance is met.

 

Never fully remove fibers from splice after initial

 

insertion. Do not pull on fiber after it has been properly

 

inserted.

4.04Prepare second fiber (strip, clean and cleave) as described in Section 3.

4.05Lay fiber into foam retention pad and begin to insert the fiber end into the splice, as in 4.01 and 4.02.

4.06Gently push the second fiber in small increments straight through the alignment guide into the fiber entry port. As the coating of the second fiber enters the fiber entry port, watch for the bow in the first fiber to increase. This occurs when the end face of the second fiber contacts the first fiber and pushes the first fiber slightly back out of the splice. Continue gently pushing the second fiber until it meets resistance.

4.07Following proper insertion, the second fiber will be approximately straight, but may have up to a .1 inch (3 mm) maximum bow. At this point, the first fiber will have a larger bow than the second fiber and larger than it had initially.

4.08Push the first fiber back against the second fiber until there are equal bows in both fibers.

Note:

Do not pull on either of the fibers following

 

 

 

of the bows in the first and second fibers.

 

establishment

 

The fiber ends must be held together by the compressive

 

forces induced by the bows to produce a low loss splice.

 

If fiber bows are NOT observed to move as described,

 

repeat steps 4.02 – 4.07 of Splice Assembly but DO NOT

 

fully remove fibers from the splice. If bow movement is

 

still not observed, remove fibers, strip, clean and re-

 

cleave, checking for proper cleave length. Re-splice per

 

splicing procedure using a new splice.

 

Do not attempt to "tune" or optimize the splice as this

 

may result in higher splice loss. The Fibrlok™ II Splice is

 

not designed to be "tuned." Fiber alignment does not

 

occur until the splice is activated.

The tape is designed to easily adhere to irregular surfaces, making it ideal for applications that require precision and reliability. Whether it is used in automotive, aerospace, or manufacturing sectors, the tape ensures a strong bond that can withstand demanding environments. Its flexibility allows it to conform to curves, edges, and protruding surfaces without losing its adhesion strength.

The technology behind 3M II 2529 incorporates advanced acrylic adhesive, which enhances its overall performance. The adhesive provides superior bonding capabilities while maintaining high resistance to temperature fluctuations, UV light, and moisture. This makes the tape suitable for both indoor and outdoor applications, ensuring that it remains effective under various environmental conditions.

Another significant characteristic of the 3M II 2529 is its excellent shear strength. This feature is vital in applications where the tape is subjected to load and stress over time. The tape's ability to resist slippage or creep, even when exposed to high pressure, ensures long-lasting performance, reducing the need for frequent replacements. This durability translates into cost savings for businesses, allowing them to operate more efficiently.

The 3M II 2529 is also known for its clean removal properties. It can be removed without leaving a sticky residue, making it an ideal choice for temporary bonding or masking applications. This feature is particularly beneficial in industries where surface cleanliness is crucial, such as electronics manufacturing and automotive assembly.

In addition to its physical properties, the 3M II 2529 is available in various widths and lengths, allowing for customization based on specific project requirements. This adaptability makes it a go-to solution for professionals across multiple sectors, as they can easily find a version of the tape that aligns perfectly with their needs.

In conclusion, the 3M II 2529 adhesive tape is a multifunctional product that stands out for its conformability, advanced adhesive technology, shear strength, and clean removal features. Its versatility allows it to be used across numerous applications, providing an effective, reliable solution for professionals in various fields. Whether for structural bonding, mounting, or masking, 3M II 2529 is a trusted choice that consistently delivers outstanding performance.
