TALON liquid trap primer from J.C. Whitlam is a specialty liquid chemical that seals drain traps to eliminate and prevent potentially dangerous odors from entering the facility through the trap. Its high viscosity prevents it from being washed out and prevents sewer gases from escaping. It is ready to use from the container and has a fresh lavender scent. The primer can be used in many instances, including hospitals, schools, vacant apartments, stadiums, factories, boats and more. 800-321-8358; www.jcwhitlam.com.
