The makers of Galaxy Hi-Tech Coatings proudly introduce   Gal-Tech POROSIL – NP which is characterized by; High bond strength, excellent penetration into the substrate and thus makes the surface waterproof and water repellent. POROSIL- NP is an anionic acrylic polymer with medium viscosity and it consists of small finely divided nano particles. Films formed by POROSIL – NP are clear, semi-glossy and exhibit superior water resistance.

BENEFITS:
Chemical barrier to salt Migration - Excellent substrate penetration - Outstanding water resistance - Excellent water repllent - Good alkali resistance

TECHNICAL DATA:

POROSIL – NP is a water based co-polymer compound containing inert monomers and special additives. It is a one component system with excellent adhesion, outstanding water resistance, good alkali resistance, chemical barrier to salt migration, excellent substrate penetration, resist algal and fungal formation.

PRE APPLICATION:

New concrete should be cured completely. All topping / finishing must be completed and allowed to be cured. In case of rains, allow the structure to dry for atleast 24-48hrs before POROSIL-NP application.

SURFACE PREPARATION:

Proper preparation of any surface is mandatory for chemical treatment. The concrete surfaces should be cleaned to remove laitance, dust, dirt, and other debris by sand-blasting. In case sand blasting is not possible, thorough abrading with a hard wire brush can be resorted to though it is not as efficient. If these methods are not feasible, chemical etching using 15% hydrochloric acid solution should be employed. The   solution is applied over the surface liberally and left in contact for 15   minutes. This is then washed off with plenty of water followed by thorough drying with hot air. Ensure a clean, rough and dry surface for a successful performance.

FEATURES:
Prevention of topcoat from defects - Excellent adhesion to all substrate - Suitable for exterior and interior application - Superior water whitening resistance - VOC and APEO free*

FORMULATION:

1.Base coat :
Mix ratio	  : POROSIL-NP - 100 parts by weight (pbw)
                    Water -   100 pbw
Coverage	  : 4-5 sq.m. area per kg of mix per coat
No. of coats      : 2
Pot Life	  : 12 hrs after mixing
Application       : For best results, the substrate should be  dried and proper surface preparation
                    must be done. It can be applied as a base coat. Suitable for both exterior and
                    interior application. This can be used at every stage of construction to prevent
                    water leakage or dampness.
2.Exposed Surface Coating (ESC) :
Mix ratio	  : POROSIL-NP - 200 parts by weight (pbw)
		    Water -   100 pbw
Coverage	  : 4-5 sq.m. area per kg of mix per coat
No. of coats      : 1 Base coat + 1 Finish coat (ESC)
Pot Life	  : 12 hrs after mixing
Application       : For best results, the substrate should be  dried and proper surface preparation
                    must be done. After application of base or primer coat this top coat formulation
                    can be applied to any exposed substrates like concrete, brick work, stone cladding,
                    wood, metal etc.. for waterproofing and excellent water repellency. It can also be
                    used as a bonding agent.

VARIOUS APPLICATIONS:

1. Basic waterproofing of new structures from foundation level to plaster level.

2. As a top coat for exposed surfaces to achieve excellent waterproofing and repellency without spoiling the aesthetic apperance

3. Protective coating for all kinds of outdoor tiles, paver blocks, claddings, pebbles, statue and metal rods.

4. Water repllent soil can be achived.

5. As a preventive coat from salt migration.
