When we choose fireproof Paint, can discover fireproof paint has intumescent type and non-intumescent type two kinds.So what difference does this two fireproof paint have?
Intumescent and non-intumescent fireproof paints are made of different materials, fire protection principles and fire-resistant time.
1.In terms of raw materials, the intumescent fireproof paint is mainly made of the mixture of foaming agent and carbonizing agent, while The non-intumescent arson coating is made of insulating material, and the material itself is refractory or non-flammable material.
2.According to the principle of fire prevention, the intumescent fire-retardant coating will expand after meeting fire, and form a uniform heat-insulating layer, thus prolonging the fire-resistant time.Non-Intumescent Fireproof Paint not change after being exposed to fire, and fire retardant and heat conduction material are used to extend the fire resistance time.
3. In terms of fire-resistant time, the fire-resistant property of intumescent fireproof paint is one to two hours, while that of non-intumescent fireproof paint is two to three hours.
