Product Description

Product Overview
The component A (white adhesive) of DF-221 Two-component PU Adhesive for EPS Composite Panel is made of the self-made polyester, which overcomes many shortcomings of traditional formula: polyether's tenacity, its strength and adhesive strength, temperature resistance are not satisfied; pure polyester's resistance to heat, and hydrolysis. By this way, the adhesive is of better properties: of superstrong binding power; bonding layer is durable and of good tenacity; stable molecular structure; being not easy to get aging; better temperature tolerance than EPS material; of good resistance to low and high temperature; no adhesive failure at 120ºC.  The component B (black adhesive) is the original material of imported polymeric MDI.

Application
DF-221 is mainly applied in various vertical, horizontal steel sandwich panel laminating machine, for bonding color-steel board (or stainless steel board, pvc plastic board, GFRP plate, etc.) and central layer of EPS board (or rock wool, glass wool, PU panel, etc.).
Of better stability, higher safety factor.

Product Features
High solid content, less consumption;
Stronger initial adhesion, higher curing speed;
Bonding firmly; better quality of composite board products;
Better adaptability to material, speed, temperature, ratio of two components;
Highly cost effective, save cost for customers.
