Wakol Intercoll D 3437 2K Activator

No—D 3437 is an activator, not the adhesive itself. It’s used as part of certain spray-mix adhesive systems, so it supports the process rather than acting as the bonding adhesive on its own.

The activator is mixed with the adhesive in the spray jet, where it causes instant coagulation of the synthetic latex. This is designed to support fast handling in compatible synthetic latex dispersion systems.

No. It must be used in combination with compatible, approved adhesive systems as the activator component in a two-component spray-mix setup.

The typical ratio is 5–10 : 1 (Adhesive : Activator). The right setting depends on your adhesive system and conditions, so it’s worth doing a short test run before full production.

For spray-mix guns, the typical spraying pressure is around 1.5–2.5 bar. Keeping the spray system stable helps you get consistent mixing and results.

Cleaning is done with water. Avoid cleaning agents that contain silicones, oils, or similar substances that can interfere with adhesion performance.

Do not inhale the spray mist—use an exhaust system and suitable personal protective equipment (such as a breathing mask) if needed. Good ventilation is especially important in continuous spray processes.

Store between +5 °C and +30 °C and protect from frost. Shelf life is up to 12 months at +20 °C in an unopened original container.

“Spray glue” usually refers to an adhesive that does the bonding, while a spray-mix activator is a supporting component used with certain two-part systems to control how the adhesive reacts during spraying. If you’re using a two-component Intercoll setup, the activator is chosen to match the specific adhesive system.

This product isn’t an upholstery adhesive by itself—it’s an activator used with compatible spray-mix adhesive systems. If your upholstery process uses a two-component Intercoll system, the correct activator is selected based on the adhesive you’re running.

For spray-mix application, you typically need a compatible spray-mix gun that supports correct mixing in the spray jet. See the Wakol Intercoll E 5998 Clean Transfer Spray Gun as an example of the type of equipment used for controlled spray application.
