Description
Permabond TA4631 is a 2-part, 1:1 no odor acrylic adhesive. It has been developed to bond low-surface energy plastics such as polypropylene and polyethylene with no primer or expensive surface treatment required. It can also be used to bond a wide variety of other materials such as metals and composite materials and is ideal for bonding dissimilar surfaces. This product is similar to TA4630 but does not contain microbeads making it suitable for joints with smaller gaps.
