PERMABOND® TA4230 is a 2-part, 1:1 toughened acrylic adhesive. It can be used to bond a wide variety of materials including metals, plastics, composites, ceramics, and other substrates. The adhesive can provide excellent shear strength on many substrates with little surface preparation. The cured adhesive has been designed to meet the fire retardancy requirements of UL94 V-0.
FEATURES AND BENEFITS
- Adhesion to a wide variety of substrates
- Fast cure at room temperature
- High shear and peel strength
- Good impact strength
- Designed to meet the requirements of UL94 V-0
