Pvac (Polyvenyl-Cetate) Wall Coating Making Plant

  1. Product Description: This wall coating material consists of white pigment dispersed in water and of a binder based on PVAC with the addition of filters, flame retardants and preservatives and is used as a protective and decorative final coat for outdoor and indoor walls. The coating may be thinned by the addition of water and is applied to walls with as roller or a brush. This coating material may be used to paint and protect walls in homes, offices and industrial, commercial and other public buildings. It may be applied to concrete and to mortar. If necessary, the surfaces should be smoothed before applying the coating.

 

  1. Market Potential: PVAC wall coating is related with the building construction industry. If this industry expands, the demand for PVAC wall coating will grow. The last ten years have witnessed a large expansion in building construction in almost all parts of the country. Buildings for schools, universities, offices, factories, shops, stores, residence, finance and commerce. etc. have been built, and are being built. There are strong indications that this trend will continue in the foreseeable future. After all, if the country has to reach a certain level of development, its building infrastructures have to be transformed from the existing dilapidated situation to a much more improved situation. Similar to other regions, the Amhara region is also experiencing modest expansion in the construction of buildings. These buildings require coating material like PVAC wall coating. Currently, the region receives it wall coating products from Addis Ababa. Like many other building materials, wall coating is a bulky product which makes it expensive to transport long distances. For meeting the existing and future demand for wall coating material, there is a need to look into the viability of establishing a PVAC wall coating producing plant in the Amhara Region.

 

  1. Source of Raw material: The main inputs for making PVAC wall coating are PVAC binder, flame retardant, pigment, kaolin, calcite and preservative. Kaoline and calcite could be obtained from domestic sources. The others will be imported.

 

  1. Process and Technology:  Raw materials are weighed and put, in the proper order, into a vessel containing water in which they are mixed. The mixer is a combination of a planetary mixer (30-40 rotations per minute giving semi dispersion) and a dissolver (1400 rotations per minute). Mortars and other products of a greater viscosity may also be produced by changing the granulometric composition of the filler or the formulation. Composition of final coating mixture for interior and exterior walls is determined according to the requirements of a particular coating procedure (brush, roller and spray). Final coating mixture is diluted by addition of water depending upon the particular bed and desired type of coating. Materials such as quatz, natural and sedimented calcium carbonates, calcium/magnesium carbonates, magnesium silicates (chalk) magnesium/aluminum silicates, and aluminum silicates (kaolin). The range of the product can be inc increased by combining methods of mixing, changing the ingredients and adding pigments, Required machinery include planetary mixer, scales, fork-lift truck and tanks.

 

  1. Estimated Investment:- For a plant which can produce 2100 tons per year (working 8 hrs/day and 300 days/year), the estimated investment will be :-

 

§  Building/shade 300m2 at Birr 1500/m2         =Birr      450,000

§  Machinery …………………………….…. = Birr   1,500,000

§  Working capital……………………………  = Birr    500,000

Total        = Birr   2,450,000

 

  1. Benefits:  Similar to other projects.

 

  1. Location: Bahir Dar, Combolcha.
