Sika Recalls Certain Cartridges of SikaTack® ASAP+ Due to Contamination, Curing Issue
July 28, 2011
Sika Corp. has issued a voluntary recall for 1,152 cartridges of its SikaTack ASAP+ adhesive. The recall includes cartridges that were packaged on February 28, 2011, between 7:30 and 8:05 a.m., with lot number 3000083574. Company officials say that a limited quantity of the product was contaminated during packaging, and that it may not cure or harden.
The company attributes the issue to “a production anomaly,” but says all of the cartridges were sold to one specific retail customer. Sika spokesperson Diana Pisciotta declined to identify the customer involved in an interview this morning with glassBYTEs.com™/AGRR™ magazine.
In Sika’s letter to the National Highway Traffic Safety Administration (NHTSA) notifying the government agency of the recall, Steve Rosenberg, senior vice president of research and development, says company officials believe only 720 cartridges were contaminated, but recalled the entire pallet of 1,152 cartridges made during this period “out of an abundance of caution.”
"We estimate 584 vehicles may have had material from the batch applied but that only a small percentage of those actually involved defective materials and needed to be replaced,” says Pisciotta.
The company initially received notification from the retailer that the adhesive had “delaminate[ed]” on a vehicle in California on May 25.
“Sika checked production retain sample product, but did not identify any problems with the material,” writes Rosenberg. “The failure therefore appeared to be attributable to an installation error.”
Around May 31, the same customer notified the company “of a similar failure involving a vehicle serviced by the same technician,” and the company found that both installations were from the same production batch of adhesive.
On June 8, the installation company notified Sika of a third “windshield adhesion concern,” related to a May 13 installation by the same technician involved in the same prior two instances.
“The vehicle owner reported that while driving at a low speed, the windshield came out and damaged the hood of the vehicle,” writes Rosenberg, who adds that no injuries occurred.
The company requested samples of the adhesive the technician was using and determined that it was contaminated and might not cure properly when applied during installation.
Company officials say they have “implemented new quality control procedures to prevent similar contamination from occurring in the future.”
"This was a very isolated incident and we are confident the product is very strong and very stable,” says Pisciotta. “Something like this is not going to happen again. We’ve taken every step to reach out to customers to make sure the installations are safe and appropriate."
The retailer that installed the glass using the recalled adhesive is contacting vehicle owners and inspecting vehicles for this condition.
"Anybody who was impacted by this would have heard from the
company that replaced the auto glass,” she says. “In
this case we reached out to most of our customers almost before
the recall notice was filed."
In addition, all affected retail locations have been advised to
search for and return any unsold inventory of the contaminated ASAP+
cartridges, according to Rosenberg.
