Material Notes:

PERMABOND TA435 is a structural acrylic adhesive designed primarily for bonding metals, ferrites, ceramics and some thermoplastics. This adhesive may be used in a variety of structural bonding applications, due to its versatile performance capabilities. TA435 provides high strength while maintaining excellent flexibility, resulting in tough, durable bonds with outstanding impact and peel resistance. Handling strength is achieved in a few minutes at room temperature by using Permabond Initiator 41. Mix ratio 10:1.5 (adhesive:initiator). Features & Benefits: Adhesion to a wide variety of substrates Fast cure at room temperature No mix application High shear and peel strength Good impact strength Good chemical resistance Information provided by Permabond.
