Dear Valued potential customer, My name is Jason from BestGuard. I would like to introduce to you some videos of demonstrations where wood, paper and hay is treated with chemical 119P to make them resistant to fire. As you'll notice from the videos, when the flammable objects were treated with chemical 119P, these materials became semi-fire retardant (Flame-retardant Level 2). I hope that chemical 119P can be beneficial to your business and our society. Thus, please visit our homepage: http://*****/fireproof.html . Thank you for your time. Best regards, Jason Lee Show More
