Product Type
FIRECUT F-1 (Exterior) Spray-applied Fire Resistive Material is designed for steel construction so as to have excellent adhesion to steel substrates. FIRECUT F-1 is formulated with materials such as cement, vermiculite, fiber (asbestos-free) and some other inorganic materials, where it does not only show the characteristic of steel strength of concrete, but also the toughness and the flexibility of the cross-stitched network of fiber. The physical properties is significantly better than equivalent products in the Market. During its burning in the fire, no toxic smoke is produced. After the burning, the burned coating remains as strong and intact as that before the burning, and it will not be destroyed by the wind-storm occurred in fire accidents.
Characteristics
1.Excellent Physical Properties
After it is applied and cured on the steel substrates, FIRECUT F-1 is tough and light. The impact resistance, compressive strength and bending durability are significantly higher than equivalent products. Due to its inclusion of tough and strong anti-deflection fiber, no peeling occurs under heavy blows. The physical properties can still be maintained even after 3 hours of burning in the fire, no chalking or loosen occurs. It can resist the wind-storm in the scene of fire accident and thus ensure its fire protection capability.
2.No asbestos Content
The test done by Union Chemical Laboratory of Industrial Technology Research Institute shows that FIRECUT F-1 does not contain any asbestos at all. F-1 is also tested by Underwriters Laboratories Inc. according to ASTM E84 (UL 723), the smoke development is zero.
3.Prohibition of Oxidation
The components of FIRECUT F-1 can prohibit the oxidation of iron, no corrosion to the steel substrates will occur under direct contact.
4.Easy Application, Low Pollution
After being mixed with water and stirred well, FIRECUT F-1 can be sprayed immediately. It has good fluidity and optimum viscosity. On top of the finished surfaces, different types of protective and decorative topcoats can be applied (not compulsory). After the application of topcoat system, it does not only provide a pleasant and colorful appearance, but also protect the F-1 from the direct contact with atmospheric pollution, thus prolong the warranty period.
5.Best Quality, Stable Supply
F-1 cementitious mixture is certified and audited by Germany TUV CERT on Design/R&D, Production, Application, Sales/Service to comply with the DIN EN ISO 9001: 2000 Quality System. Together with 『Follow-up Service』by U.S. Underwriters Laboratories Inc. and the annual production of millions of bags by automated production facilities, the stability of quality and quantity supply of F-1 is definitely more superior than that of the domestic and overseas products.
6.Fire Testing Certification
(a)F-1 has passed the test of UL 263 (ASTM E119) Fire Test of Building Construction and Materials by Underwriters Laboratories Inc. It has the capability of protecting exterior and interior structural steel beams and columns and floor units up to 4 hours, and is registered as 『Design No. N 768, Y 701, Y 703, Y 706, Y 711 and D 778 』 and categorized as Fire Protection Coating for Interior Structural Steel in General Building Construction in the Fire Resistance Directory which is published annually.
(b)F-1 passed GB 14907-2002【All Performance Type Tests】on Fire Protection Coating for the Interior Thick Structural Steel by National Center for Quality Supervision and Testing of Fire Building Materials (NFTC) in Dujiangyan, Sichuan City of China. It is registered in the official website of National Center for Quality Supervision and Testing of Fire Building Materials, and is categorized as Fire Protection Coating for Thick-coat Interior H-type Structural Steel.
(c)F-1 was also tested by Warrington Fire Research Centre in U.K. according to BS 476 : Part 21 : 1987 Standard and certified to acquire the fire protection capability up to 4 hours. It can be used I (H)-type steel sections for beams and columns, tube steel beams and tube & circular steel columns.
Suitable Coating
Because the fire protection coating belongs to porous coating and is always exposed to exterior environment, the addition of the acidic & alkali- resistant, water-resistant and chemical resistant coating system with good adhesion will increase the durability and overall appearance of the fire protection coating.
Suggested System: Spray the clear or colored water-based Emulsion Paint.
(1) Type:Clear or various colored Water-based Acrylic Emulsion Paint.
(2) Product No.:FIRECUT FW-33 or various colored Acrylic Emulsion Paint.
(3) Total Dry Film Thickness:Suggest to apply at least 2 coats, min. D.F.T. > 40µm.
(4)Description of Application :
(i) Method of Application : Brush, roller or spray application.
(ii) It must be well-stirred before the application. If it is too concentrated, appropriate quantity of
water can be added for dilution.2
- Grease, dust and any other adhered sludge on the surface of substrates must be cleared before the application.
- The newly completed coating contains a vast amount of water and alkali materials which in turn reduce the coating performance and adhesion. It must be put aside and completely cured for 2 ~ 3 weeks until the water absorption rate is below 12% before the application.
