Common Concerns Answered
Why do I need to buy a separate hardener for Sika SikaBiresin AP112?
Sika SikaBiresin AP112 is a two-part system, and the BPO hardener is essential for initiating the chemical reaction that cures the resin, achieving its specified strength and rapid setting properties. Purchasing the hardener separately ensures optimal product freshness and allows for the correct ratio for critical repairs.
Is Sika SikaBiresin AP112 messy to work with?
Due to its thixotropic paste consistency, careful application is recommended to prevent excess material from being dispensed. Proper surface preparation and the use of appropriate tools will help manage the material effectively, ensuring a clean and precise repair.
How does the need for a separate hardener impact cost?
While the initial purchase price reflects the paste component, the performance benefits of Sika SikaBiresin AP112 for demanding composite repairs, including its strength and rapid curing, often justify the combined cost for professional and critical applications where reliability is paramount.
