Esscoat PC

Pre-fabricated steel frame fire resistive prelite spraying

The Esscoat PC, manufactured by the PREFAB spraying method, is a fire resistive spraying material that is manufactured and commercialized in the factory, providing uniform quality and reducing the time for construction.

Esscoat PC

Features

What is the prefab spraying method?
(Prefab)

It is the off-site construction technology that not only reduces construction time by pre-construction at the factory and installation on the site, but also possible to provide the uniforrm product quality improves the shortcomings of conventional on-site spray method.

Product Features

01

Reduction of the period for construction

Rapid drying allows movement after 5 days of curing. The long curing period, which is a disadvantage of conventional fire resistive spray techniques, can be shortened, hence reducing the period of time for construction.

02

Plastering finish possible

After construction, it can be groomed with trowels or plastering tools.

03

Cost saving

Reduce the cost of quality control and safety management in the site. Reduced production costs without requiring for rust preventive painting.

04

Eco-friendly spraying method

Resolving the problems caused by dust and scattering in the field by off-site construction technology.

Reduce waste generation.

Esscoat PC Construction Method

Preparation for work
  • Operation timingIn principle, construction shall be carried out at the time of completion of basic construction for anchors, hangers, ceiling structures, etc. necessary for all DUCT works, piping works, etc.
  • Surface treatment In principle, dust, release agents, rust, oil, grease, paint, etc. that may impair adhesion to the surface to be constructed shall be removed. In addition, since adhesion is reduced when construction of the condensation generating area, construction is performed after removing the moisture.
Construction method
  • Measures shall be taken to ensure that the work period, surface treatment, and on-site occupational conditions do not interfere with construction.
  • During construction, the COMPRESSOR pressure shall be 5±1 kg/cm, and the air volume shall be 0.4 mM/MIN or more.
  • The distance between the tip of the nozzle and the construction surface shall be 30 to 60 cm, and the construction angle shall be maintained at 90°, but construction of not more than 70° shall be prohibited except in special case
  • The mixed material shall be constructed with reference to the nozzle tip 10 mm. However, when changing the nozzle diameter depending on the working conditions, the amount of construction work or the roughness of the construction surface may vary.
  • For mixing the product and water, Mix Esscoat PC and water in a weight ratio of 1:1.0 to 1.2 for 2 to 3 minutes.
  • The mixed product must be used within 30 minutes, and after 30 minutes, it can be reused when a small amount of water is added and mixed again to produce a viscosity similar to the initial one.
  • However, discard products that have passed 1 hour.
  • Esscoat PC can be constructed having certified thickness with one-time construction. (3 hour flange end construction caution)
  • Construction thickness shall be measured with a thickness measuring gauge and shall be constructed with a thickness greater than the approved thickness.
  • Over-construction during curing may cause discoloration, so it should be avoided, and the area where the falling or the crack occurs is, supplementary work is carried out in consideration of the degree of curing.
  • If necessary, it may be decorated with dirt hands or plastering tools immediately after construction.
Curing

Rapid drying should be avoided in places with adequate ventilation, and the curing period is as shown in the table below.

Temperature / Construction thickness Beam

Certified thickness (mm) 28(23)mm 29mm
Summer (40℃ or lower) 9~10 days 9~10 days
Spring, Fall (10~20℃) 10~11 days 10~11 days
Winter (4℃ or higher) 12~14 days 12~14 days
