Development Of New Hot-Melt Adhesive Products

Curing hot-melt adhesives and functional hot-melt adhesives represent two major categories of new products on the market. The former are characterized primarily by enhanced high-temperature resistance-raising the softening point to over 120°C-thereby expanding their application range. Functional hot-melt adhesives, on the other hand, are designed for specific scenarios to deliver specialized functions that meet diverse application needs; examples include water-soluble or water-dispersible hot-melt adhesives, hot-melt sealants, and hot-melt pressure-sensitive adhesives.

 

This product is a single-component, solvent-free, non-fogging, non-vulcanizing, and permanently plastic primary sealant for insulating glass, based on polyisobutylene rubber. Hot-melt butyl sealant maintains its plasticity and sealing performance across a wide temperature range without surface cracking or hardening. It exhibits excellent adhesion to materials such as glass, aluminum alloy, galvanized steel, and stainless steel.

 

Thanks to its extremely low water vapor transmission rate, it works in conjunction with elastic sealants to form a superior moisture-resistant system. Key features include: excellent sealing performance and consistent quality; no curing period required, saving floor space; eco-friendly nature with zero waste and a clean working environment; and savings in time, raw materials, and labor, resulting in reduced production costs.
