[0155] The first part of the two-part adhesive composition samples was prepared according to Tables 1A and 1B. The components in the first part were mixed well at 50°C, then the first part was cooled to room temperature.
[0156] The second part of the two-part adhesive composition samples was prepared according to Tables 2A and 2B. MD 1652, Epoxy828 and DOA / DOTP were first mixed at 100°C for 5 hours, then the mixture was cooled to room temperature. BPO and Ultramarine blue colorant (available from Tianlan) were further added to the mixture with stirring to form the second part,

Abstract
Provided is a two-part adhesive composition, comprising a first part comprising at least one ethylenically unsaturated monomer, at least one non-polar styrenic block copolymer, and at least one curing promoter; and a second part comprising at least one initiator. The two-part adhesive composition exhibits excellent adhering strength to both metal substrate and plastic substrate.
Description
technical field [0001] The present invention relates to a two-part adhesive composition comprising a first part and a second part, the first part comprising at least one ethylenically unsaturated monomer, at least one non-polar styrenic (styrenic) block copolymer and at least one curing accelerator, the second part comprises at least one initiator. The two-part adhesive composition exhibits excellent bond strength to both metal and plastic substrates. [0002] Background of the invention [0003] In many cases, it may be necessary to bond substrates of the same material or different materials together. However, different materials have different surface energies, and it is difficult to have an adhesive that can be used to bond high surface energy substrates, such as copper, aluminum, and stainless steel, while being able to bond low Surface energy substrates such as polyvinyl chloride (PVC), polycarbonate (PC) and polyethylene (PE). [0004] The challenges of bonding high ...
