Bonapur BA


BONAPUR® BA adhesive is based on special flexible polyurethanes and modifiers, which distinguish it from other adhesives, due to low speed of crystallization. Due to specific properties of starting raw materials, the adhesive can be used for bonding various types of materials without prior thermal activation of the joint (It should be noted, that thermal activation increases strength of the bond). BONAPUR BA can be applied as both one-component and two-component adhesive, eg. with the addition of 3-5% Quidur 246-06 hardener. The adhesive is also produced in a non-toluene form as BONAPUR® BA BT.


BONAPUR® BA is designed for footwear industry, as well as for repairing shoes, for bonding natural and synthetic leather, for bonding cloth with soles made of polyurethane, soft PVC and halogenated rubber. Can also be used in other industries for bonding aforementioned materials.
