TH-V801 Two-Component Fire-Rated Door Assembly Adhesive (EN 204/D4) is an elite engineering bonding solution specifically developed for the manufacturing segment of fire-rated wooden doors, thermal insulation doors, and premium architectural woodwork components. Inheriting the ultra-strong physical and mechanical foundation of the renowned TH-V111 line, TH-V801 is enhanced with a proprietary system of heat-resistant additives combined with a specialized Isocyanate crosslinking hardener. The product generates ultimate cohesive strength and superior water resistance that meets the strict international EN 204/D4 standard, firmly anchoring timber layers and completely eliminating delamination, glue failure, or joint distortion when exposed to harsh environmental shifts in temperature and humidity.

The product is seamlessly optimized for the manufacturing of functional doors and load-bearing, heat-resistant architectural woodwork:

• Primarily used in the structural bonding of wooden stiles and rails, surface panel lamination, and multi-layer press assemblies for fire-rated wooden doors (meeting technical classification standards for joinery fire rating).
• Provides high tensile strength structural jointing for interior and exterior architectural doors, as well as finger-jointed lumber requiring a highly rigid and durable adhesive film.
• Delivers ultra-strong adhesion to most species of hardwood, plantation timber (acacia, rubberwood, oak, walnut), and specialized substrate materials used in door manufacturing.

TH-V801 has successfully passed rigorous evaluation processes at independent quality verification bodies, offering a comprehensive technical data portfolio to satisfy the demanding requirements of project contractors:

Certificate of Conformity with EN 204/D4 International Water Resistance Standard

International Safety Certification for Woodworking Industry Materials

Test Report on Bonding Strength & Consistent Thermal Cycle Resistance

Environmental Quality, Workplace Health & Safety Certification

Below are the empirical measurement data of the TH-V801 fire-rated two-component adhesive system when mixed with the AP hardener/catalyst:

* Usage Instructions and Precautions: To ensure the adhesive film achieves ideal high-temperature mechanical properties for door structures and complies with the EN 204/D4 water resistance standard, please precisely follow the uniform mixing process of TH-V801 base adhesive and AP CATALYST according to the specified ratio directed by the factory's technical manual.
