Product Description of PERMABOND® TA4230
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 of PERMABOND® TA4230
- 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
Surface Preparation for PERMABOND® TA4230
Surfaces should be clean, dry and grease-free before applying the adhesive. Permabond Cleaner A is recommended for the degreasing of most surfaces. Some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.
