Thioxo Coating of Polyurethane
Scope of Application:
Mainly apply to food processing plant, chemical storage area, warehouse, toilet, laboratory, foodstuff factory, and chemical plant, etc. Excellent chemical resistance and wear resistance.
Substrate Preparation:
Concrete substrate must be prepared mechanically using abrasive blasting cleaning or grinding machine to remove cement laitance and achieve an open textured surface. All dusts, oil, grease, loose and friable material must be completely removed from all surfaces before application of the product, preferably brush and/or vacuum. Concrete substrates must be sound and of sufficient compressive strength (minimum 25N/mm2) with a minimum pull off strength of 1.5 N/mm2.Repair to the substrate, filling of blowholes/voids and repair to irregular surface with suitable Sika’s repair mortars.
Application: Material: Sikafloor 31N Purcem. The material must be placed under 18~25℃. Mixing: Prior to mixing, stir part A mechanically. When all of part B has been added to part A for about 30 seconds, then all of part D (pigment) is added. Mix continuously for about 2 minutes until a uniform mix has been achieved.Coating: Coating with middle/short wool roller. The consumption is approximately 0.28~0.35 Kg/m2, the thickness will be 0.2~0.25mm.Anti-slip texture: Before curing of 31N Purcem, broadcast special mineral aggregate in time, then seal with 31N Purcem. Hardening time: Potlife: 20-25min (20℃); Initial setting time: 25-30min(20℃); Foot traffic: 14-16 hours (20℃); Light traffic: 36-48 hours(20℃); Full cure: 5 days ( 20℃).
