2018/9/2The Toughener is a urethane group -containing elastomeric toughener containing bisphenol-blocked isocyanate groups. It is prepared using general methods as described, for example, in Example 19 of US 5,278,257, by reacting a 2000 molecular weight polytetrahydroiuran with isophorone diisocyanate to form a urethane group -containing, isocyanate-terminated prepolymer, and then

Fire Retardant Coatings

2016/10/13Fire retardant coatings are often required to protect a wide range of products of both flammable and nonflammable against fire. It is an oldest, most efficient, and easiest method to apply any surface without modifying the intrinsic properties of materials. Moreover, the initial phase of fire always occurs on the surface by ignition, and hence, it is important to concentrate on the surface

Intumescent Coatings Based on Tannins for Fire Protection

The intumescent coatings containing DOPO (TAN-10BM-P) produced a lower amount of residue (32.02%), approximately 4.35% lower than TAN10-BM. This behaviour was expected since DOPO mainly acts in the gaseous phase in providing flame retardant action.

Evaluation of compression strength of intumescent char

Intumescent coatings employ the heat barrier effect of an expanded char in the fire protection of the underlying substrates. The effectiveness of an intumescent system is dependent on the strength and ability of the char to remain intact upon exposure to fire. Many approaches have been employed to measure the strength of the intumescent char, but there still remains the need for an established

Polymers for Cardiovascular Stent Coatings

Polymers have found widespread applications in cardiology, in particular in coronary vascular intervention as stent platforms (scaffolds) and coating matrices for drug-eluting stents. Apart from permanent polymers, current research is focussing on biodegradable polymers. Since they degrade once their function is fulfilled, their use might contribute to the reduction of adverse events like in

The expandable graphite may be acid-treated graphite that can expand under heat to a volume up to 300 times its original volume. This cover layer better meets the conflicting requirements of melting to provide a liquid-liquid interface for removal of unwanted inclusions from the molten steel and maintaining a solid covering layer to provide effective thermal insulation.
