This adhesive system a reactive type, with simple operation, strong stick, film water, solvent and weather resistance and good; can be used for wood puzzle and tenon (or assembly); especially for rosewood, mahogany bonding. Main component consists of a polyisocyanate and polyether polyols made of moisture-curing polyurethane reactive adhesive technical indicators Appearance: brown yellow transparent viscous liquid Solid content: 67 ± 2 Viscosity (25 ℃, mPa.s): 800 - 1500 Performance and Features 1, the product is exposed to moisture while curing one-component adhesives novel; 2, it has a high bonding strength (destructive testing: mahogany destruction), good weather resistance, easy to use, water-resistant film , solvent resistance and flexibility characteristics. Use 1, the surface to be bonded shall be dust, oil, remain to be sticky surface clean and dry; no adhesive grease or hazardous substances isolation agent; 2, glue evenly coated surface to be bonded; 3, glue to be placed after 1-8 minutes (but not more than 30 minutes) after pressure bonding, pressure bonding surface must ensure close fit, applied pressure is generally 0.6-0.8Mpa; timely pressure must remain tacky film; opening hours depending on the construction environment, high temperature and humidity will shorten the opening hours; 4, pressing time depends on the construction environment and sticks the temperature and humidity; 5, when using this adhesive puzzle (eg: Bonding mahogany), film post- Processing time (ie, after bonding over shaved Saw time) is 10-15 hours, may continue the next process, the film reaches the final bond strength time (can be destructive test) is 24-36 hours later.
