Primer application – Case #555

“A picture is worth a thousand words”. Practical solutions to problems encountered in the manufacturing process that demonstrate how we assist our customers’ factories to produce Right from the Start TM.

Problem: the factory was using a plain nylon brush to apply primer on outsoles. This brush cannot hold the primer due to its low viscosity, what poses a risk of not applying sufficient primer. This may affect the sole bonding.

Impactiva solution: we got the factory to cover the nylon brush with a piece of cotton cloth in order to increase the quantity of primer applied to the outsoles, what will enhance bonding strength.
