Two-component polyurethane adhesive for sandwich lightweight panels; reactive hot melt.
Krylon Sandwich Lightweight Panel Adhesive
A wide variety ranging from high heat-resistant reactive hot melts for instant bonding and cross-linking to two-component polyurethane adhesives that have a long usable time and cure in a few minutes!
In the manufacturing of sandwich lightweight panels, we are developing products based on various materials used and PUR (polyurethane) adhesives that can bond them. We offer a highly heat-resistant reactive PUR hot melt adhesive that undergoes a crosslinking reaction after instant bonding, as well as a two-component heat-accelerated polyurethane adhesive that has a long working time and cures in a few minutes at around 70°C in a hot press. Additionally, we provide high-transparency adhesives with minimal yellowing for bonding polycarbonate sheets and aluminum honeycomb cores, as well as adhesives that meet the European fire safety standard A2 grade and the IMO marine fire safety standard. 【Product Examples】 ■ Highly heat-resistant reactive PUR hot melt adhesive that undergoes a crosslinking reaction after instant bonding ■ Two-component heat-accelerated polyurethane adhesive with a long working time that cures in a few minutes at around 70°C in a hot press ■ High-transparency adhesive with minimal yellowing ■ Adhesives that meet the European fire safety standard A2 grade and the IMO marine fire safety standard *For more details, please request documentation or view the PDF data available for download.

basic information
Our reactive PUR hot melt series offers a wide range of product items, allowing for a selection of initial adhesion speed from a few seconds to a few minutes, as well as the choice of hardness after curing. We also provide two-component reactive polyurethane adhesives, not only in room temperature curing types but also in heat-accelerated types that cure in a few minutes using heating equipment such as hot presses. This enables product selection that aligns with your existing equipment and line speed, minimizing initial investment and maximizing production efficiency. Additionally, we offer a variety of certified products that meet building fire safety standards and marine fire safety standards, adhesives for difficult-to-bond materials, and adhesives with minimal yellowing.
