Product Description of PERMABOND® TA4631
PERMABOND® TA4631 is a 2-part, 1:1 no odour* acrylic adhesive. It has been developed to bond low surface energy plastics such as polypropylene and polyethylene (LDPE, HDPE và UHMW) – 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 micro beads making it suitable for joints with smaller gaps.
